A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Review of the NIHR Specialist Biomedical Research Centre for Ophthalmology at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology, and UCL Partners Eyes and Vision Theme National Institute for Health Research The goal of the National Institute for Health Research is to create a health research system in which the NHS supports outstanding individuals, working in world-class facilities, conducting leading-edge research focussed on the needs of patients and the public. This is the declared goal of the National Institute for Health Research (NIHR), which was established by the Department of Health in 2006 to drive forward a five-year strategic plan entitled ‘Best Research for Best Health: a new national health research strategy’. To drive innovation in the prevention, diagnosis and treatment of ill health and to translate advances in biomedical research into NHS practice, the NIHR created 12 Biomedical Research Centres (BRCs) nationwide through partnerships between the NHS and universities. The NIHR Biomedical Research Centre (BRC) for Ophthalmology was founded in April 2007, and is jointly run by Moorfields Eye Hospital NHS Foundation Trust and the University College London (UCL) Institute of Ophthalmology. It is the only national BRC that is dedicated to vision and eye disease.

During this time our hospital has developed a unique reputation for high-quality and expert patient care, as well as outstanding and groundbreaking research into eye disease and therapeutic interventions. In 2009/10 we recorded more than 330,000 outpatient attendances in our clinics and almost 70,000 attendances at our specialist Accident & Emergency Department. Over 27,000 in-patient and day case procedures were performed, and around 8,500 laser treatments were carried out. We currently provide ophthalmic care at our hospital in City Road in central London, as well as at 12 other sites in and around the capital, which means we are able to provide care and expert treatment closer to patients’ homes. 2 The UCL Institute of Ophthalmology attracts researchers of the highest international calibre, exploring fundamental and applied questions in the science of vision. The mission of the UCL Institute of Ophthalmology is to develop new treatments for eye disease out of a large and varied foundation of basic research. The UCL Institute of Ophthalmology is also part of UCL Biomedicine, one of the largest aggregates of biomedical expertise in the world. Moorfields Eye Hospital, the world’s longest-established eye hospital A Vision for Vision Making tomorrow’s sight-saving treatments a reality today The range of diseases we study extends from inherited retinal degenerations affecting young children to age-related macular degeneration and glaucoma, the most common causes of blindness in the elderly. Currently we have groups investigating every stage of the visual process from the mechanics of rods and cones to the brain’s interpretation of complex visual scenes. Our researchers are making progress in understanding the basic mechanisms of blinding disease and investigating new methods of treatment by conventional pharmacology, gene therapy and cellular therapy, including stem cells. Strength in partnership Combined, our joint site has the highest measure of scientific productivity and impact in the world for ophthalmic research activity. We continue to build a strong team of academic, research and clinical colleagues, to explore different ways of finding better treatments, and to help our patients access new procedures and treatments as quickly and safely as possible. In whatever capacity you may be associated with our BRC, we hope you find the following description of some of our achievements as interesting and inspiring as we do. Together, we can really make a difference to people’s lives. UCL Institute of Ophthalmology, one of the largest eye and vision research institutions in the world Our strategy Our strategy is based around six themes defined by major common eye problems or disease processes. We target disease areas that are both clinically significant and identified as important to patients and their relatives. We continue to prioritise areas where there is an outstanding existing track record of translational achievement (turning laboratory discoveries into patient benefits) and expertise at an international level. We have built support and infrastructure around these themes, growing strategic partnerships and collaborations and building capacity to support and consolidate all the links of the translational bridge. As a result, new treatment techniques and practices that improve patient health are brought through as quickly as possible, which benefits patients, as well as the NHS, universities and the UK as a whole. Our aim is to be the development site of choice for rapid-track delivery of new diagnostic methods and therapies, developed both internally and in partnership with companies and charities entering at any stage of development. 3 Overview of our research themes Our six core research areas are: age-related macular degeneration; diabetes; glaucoma; ocular repair, regeneration and pharmaceutics; ocular surface disease; and paediatrics and inherited eye disease. Visual impairment and blindness can have a substantial impact on a patient’s perception of their quality of life. Patients equate the impact of loss of vision with suffering a stroke or having an advanced form of cancer. Our aim is to improve the treatments and ultimately the quality of life of those who suffer from visual loss. We are making great advances but there is still a tremendous amount of work to be done. Below, we introduce our themes, and a summary of the objectives of each theme. Age-related macular degeneration Diseases of the retina are the commonest cause of blindness across all age groups. The greatest research challenges lie with the diseases that have limited options for treatment, affect many people and/or are increasing in prevalence. Age-related macular degeneration (AMD) qualifies on all three counts and is therefore at the forefront of our research strategy. AMD is responsible for over half of blindness registrations in the UK. For more information, see pages 6 and 7. Diabetes Diabetic retinopathy is the leading cause of blindness in people under the age of 60 in the UK. Visual loss has a devastating impact on individuals’ quality of life and the socio-economic cost is huge, estimated to be around £2 billion 4 per year. At Moorfields and the UCL Institute of Ophthalmology we are committed to addressing visual loss in diabetes in accordance with the St Vincent Declaration (a set of goals for the medical care of people with diabetes published following an international conference in 1989) to enable people with the condition to lead independent lives of high quality. For more information, see pages 8 and 9. A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Glaucoma Glaucoma is the most common neurodegenerative disease in the world and the most common cause of irreversible blindness. It affects more than 70 million people, of whom more than 7 million are blind. If detected early, through regular monitoring of pressure in the eye (intraocular pressure), visual loss can usually be stemmed. Ocular repair, regeneration and pharmaceutics In our work to prevent scarring as a result of surgery, we have been at the forefront of translating several new treatments from basic laboratory discovery through to large-scale The ultimate goal is to reduce the burden on the individual and on society of visual impairment and blindness from glaucoma, and to lessen the impact of the diagnosis of glaucoma and subsequent treatments on the patient’s quality of life. Worldwide, there is only a handful of centres with a comparable expertise in the study of this group of complex diseases and the molecular analysis of ophthalmic genetics. For more information, see pages 10 and 11. international trials and improved clinical treatments for patients in the UK and around the world. We are focussing on developing final dosage forms of medicines used to control post-operative scarring in the eye, and are moving towards clinical trials for our tissue tablet. For more information, see pages 12 and 13. Ocular surface disease Ocular surface disease covers diseases of the conjunctiva and cornea. These range from minor to sight-threatening and are the commonest reason for patients seeking eye examination in primary and secondary care settings in the UK. Moorfields Eye Hospital and the UCL Institute of Ophthalmology have a long track record in the investigation of ocular surface disorders. We have focussed on diseases that result in the dysfunction and death of limbal epithelial cells that can lead to chronic corneal ulceration. Current research is directed at improving the results of corneal transplant therapy. For more information, see pages 14 and 15. Paediatrics and inherited eye disease The major causes of treatable childhood blindness are inherited eye disease and developmental abnormalities of the eye. Our main priorities for research are to identify the genetic basis of these disorders and, through basic and translational research, develop new and improved treatments for patients. We are at the beginning of an exciting new era where untreatable blinding genetic eye disease will be amenable to treatment. For more information, see pages 16 and 17. 5 Age-related macular degeneration Work within this theme includes new improved treatments for ‘wet’ AMD and, based on basic laboratory understanding and epidemiology studies, the development of novel interventions and preventative strategies for the currently untreatable forms of ‘dry’ AMD. Age-related macular degeneration (AMD) is the leading cause of severe visual loss in Europe and North America and, with an ageing population, the burden of this disease is projected to increase dramatically. As its name suggests, AMD predominantly affects the macula, the centre of vision that is important for reading and detailed vision. It can be classified into early and late stages based on specific clinical features. Early AMD is characterised by the presence of drusen (tiny yellowish deposits under the retina) and is compatible with reasonable vision. However, many patients with early AMD progress to the vision-threatening late forms of AMD. The late wet or neovascular form is characterised by the growth and leak of abnormal blood vessels beneath the macula, causing severe loss of vision. 6 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today MR Adnan Tufail Theme leader – Age-related macular degeneration Consultant ophthalmic surgeon at Moorfields Eye Hospital and senior lecturer at UCL Institute of Ophthalmology Currently, we have treatments for late neovascular AMD but these involve an intensive intervention with frequent injections into the eye and long-term monthly follow-up of the patient, which is problematic to deliver, and only a third of patients recover some of their lost vision. We have no effective treatments for the late dry atrophic form of AMD, or effective interventions for early AMD. “The challenge to develop effective treatments for patients with AMD is having the right spectrum of expertise to turn a novel idea into The atrophic form of AMD for which no treatment exists. A trial of a novel intervention for this condition will commence next year Above left: Optical coherence tomography (OCT) features of drusen. Drusen are tiny yellow or white deposits that are seen in the retina, and are a characterisation of macular degeneration at an early age a practical intervention. The team we have includes experts in genetics, vascular and stem cell biology and gene therapy as well as in clinical trials and visual function measurement. This cross-cutting approach is delivering clinical trials of new treatments in the next two years.” Adnan Tufail Examples of our research projects: The London Project to Cure Blindness (AMD) One of our approaches to treating AMD is through the ground-breaking research of the London Project to Cure Blindness, which is led by Professor Pete Coffey at the UCL Institute of Ophthalmology. Pete and his team aim to replace the retinal pigment epithelium cells (RPE) at the back of the eye that are affected in AMD, using human embryonic stem cells (HES) that have been transformed into RPE cells. They seek to transplant these RPE cells into the patient on a specially engineered patch that will be inserted behind the retina. Another important arm of the project is to develop the technology by which HES cells can be transformed into photoreceptors (lightdetecting cells) and transplanted into patients. It is believed that the photoreceptors are lost after the RPE have degenerated. We are now ready to initiate the safety studies that we need to do prior to clinical trials, and are on track to begin human clinical trials during 2011. Considering that these will be the first human embryonic stem cell trials in the UK, the project really will be breaking new ground. A novel intervention to treat geographic atrophy (late dry AMD) There is currently no effective therapy to prevent progressive vision loss in patients with atrophic AMD. In 2011 we will commence a pioneering clinical trial of a novel intervention that prevents the build-up of a key waste product that damages the cells under the retina. As a precursor to this trial, the study team at Moorfields and the UCL Institute of Ophthalmology are developing new ways of assessing atrophy disease progression, and functional changes in patients with this disorder to allow for more effective clinical trial design. The ABC trial for wet AMD Current strategies for the use of drugs to treat neovascular AMD lead to gradual drop-off in vision, which means that the benefits of these intensive treatments are being lost with time. Moorfields was the lead and coordinating centre of an important randomised multi-centre trial. Using an anti-VEGF drug (a substance that prevents the formation or growth of new blood vessels) resulted in not only the recovery of lost vision on average, but also the development of an individualised retreatment algorithm. This maintained benefit over time, with a reduced treatment burden relative to current interventions. 7 Diabetes The programme of translational research for this theme extends from the laboratory investigation of the mechanisms of retinal disease to clinical trials of new medical and surgical interventions. Diabetes is the commonest cause of blindness in young adults. The aim of the diabetes research theme is to protect people from loss of vision by improving the diagnosis and treatment of diabetic retinal disease. We have a broad strategy that integrates distinct but complementary programmes of research to translate progress in scientific research into effective new interventions. These research programmes include the development of highly sensitive diagnostic imaging techniques and powerful new therapies. “It is hugely rewarding to see how progress in basic science can be translated into new interventions that have a real impact on people’s lives. The ability to observe individual cells and molecules in the retina non-invasively is tremendously exciting. This offers a unique insight into the effects of diabetes on the retina that is certain to lead to improved outcomes.” James Bainbridge 8 MR James Bainbridge Theme leader – Diabetes Consultant ophthalmic surgeon at Moorfields Eye Hospital and Wellcome Advanced Fellow at UCL Institute of Ophthalmology Diagnostic imaging techniques The retina can be studied in unique detail because it is accessible to optical imaging. We are using high-resolution cellular and molecular imaging techniques to study the effect of diabetes on the retina and the impact of therapeutic interventions. We are working to develop imaging and psychophysical techniques to help us to understand the relationship between changes in retinal structure and function. As a ‘window’ to the brain, imaging of the retina enables us to study mechanisms of disease relevant to the central nervous system. Consequently, we are collaborating with neurologists to identify biomarkers of vascular disease in the retina that can be used as tools for the prevention of stroke. A Vision for Vision Making tomorrow’s sight-saving treatments a reality today “The work includes local, national and international collaboration and this is what makes the Reading Centre an exciting place in which to work.” Dr Tunde Peto (right) Head of Reading Centre Above left: Maintaining healthy circulation in the retina is critical for sight Powerful new therapies Recent scientific advances in our understanding of the mechanisms involved in diabetic retinal disease have led to the identification of new targets for treatment. The first results of an ongoing clinical trial demonstrate that intraocular delivery of a VEGF inhibitor (a substance that prevents the formation or growth of new blood vessels) can improve visual outcome in people with diabetes, benefiting five times more people than conventional laser treatment. We are also working to understand the impact of diabetic retinal disease on people’s abilities to perform the essential activities of daily life. By offering hospital-based vision rehabilitation services to people with diabetes, we will investigate in detail the effect of diabetes on people’s sight. The results of this work will inform the future development of services to enable people with diabetes to make the most of their visual ability. The Reading Centre The Reading Centre provides vital objective evaluation of images for clinical epidemiological studies and clinical trials. It has a broad role within the BRC that includes teaching and training, research into the best methods of image analysis, and validation of new imaging techniques. Dr Jacob is a busy inner-city GP whose life has changed as a result of recent translational research. His story is typical of many for whom diabetes has a devastating effect: despite conventional laser treatment, his failing sight began to affect his ability to work. Recent research led by Mr Phil Hykin at Moorfields has helped to demonstrate that a new injectable treatment targeting the VEGF molecule can dramatically improve the outlook for people with diabetic eye disease. Following a course of injections, Dr Jacob was enormously relieved to experience a substantial improvement in vision and has been able to continue his work with renewed confidence. “This has made a significant difference,” he says. “I was struggling to read but now my sight is back to normal.” “Anti-VEGF injections significantly improved the outcome compared to conventional laser treatment. We expect that anti-VEGF injections will supersede laser as the optimal therapy for certain kinds of diabetic eye disease in the next few years.” Phil Hykin 9 Glaucoma Glaucoma affects 2% of those over 50 years old, but 5% of those over 80 years. Therefore, with an increasingly ageing population, glaucoma is becoming a much more common condition, with half of glaucoma cases being undetected until the disease has caused some loss of vision. Early detection is thus essential to prevent blindness, and appropriate strategies should be adopted to manage glaucoma once a diagnosis has been confirmed. The key areas of research are: diagnosis; monitoring and measuring disease progression; establishing risk factors for glaucoma; and evaluating the impact of disease on the individual. “Our research strategy is focussed on patients’ needs. My research team has expertise across many fields, from diagnostic tests to measuring the impact of vision loss on everyday activities. Much of my research programme is translational, turning laboratory discoveries to patient benefit.” David Garway-Heath Professor David Garway-Heath Theme leader – Glaucoma Consultant ophthalmic surgeon at Moorfields Eye Hospital and International Glaucoma Association Professor of Ophthalmology and Allied Studies at UCL Institute of Ophthalmology affected by the presence of cataract and refractive error. Moorfields patient Carol Bronze describes her impressions of the Moorfields MDT: “I have been involved with the MDT testing at Moorfields Eye Hospital, where I am a patient, for several years now. I assisted as one of the trial patients when the testing was being pioneered and I Our key areas of study include: found the equipment and procedure incredibly easy to use. Both the explanation of how to use the The Moorfields Motion Displacement Test programme and the functionality made the whole (MMDT) testing experience easy and quick. Testing of the This is a new test for glaucoma diagnosis that has arisen as a result of 20 years’ work. It is affordable, eyes can be distressing, tiring and lengthy. I found the MDT test so easy to use, I was happy to return to portable, easily understood by patients and is not 10 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today “Since I was diagnosed with glaucoma six years ago, Moorfields has played a huge part in my life – from regular appointments every week to numerous different operations. At some points, it seemed as if I would never return to school full time, or lead a ‘normal’ life, but thanks to Moorfields and their research I have been able to do so. Without their treatment, help and support, my life would have been very different, and I cannot thank them enough for what they have done for me and my family.” Julia Margetts, Moorfields patient Above left: A glaucomatous optic disc help refine it whenever I was needed. Indeed, I would be happy to take part in further testing as all patients should have an opportunity to use a procedure that makes life easier for them.” Combining visual fields and imaging for glaucoma diagnosis Imaging is used to monitor the structure of the optic nerve while a visual field test measures its function. Recently, we have investigated the use of information obtained through imaging to supplement that obtained through visual field testing, with the aim of diagnosing glaucoma earlier and reducing the variability of current tests. Monitoring intraocular pressure Intraocular pressure (IOP) is the major risk factor for glaucoma development. We are constantly evaluating new devices to measure IOP and are also developing better-performing devices. he UK Glaucoma Treatment Study and T the UK Glaucoma Risk Factor Study Our main clinical trial is the UK Glaucoma Treatment Study (UKGTS), which is the first and only randomised placebo-controlled trial in the medical treatment of glaucoma. We are now extending the trial to the UK Glaucoma Risk Factor Study (UKGRIFS). The EPIC Norfolk Study – eye and vision module The European Prospective Investigation of Cancer (EPIC) investigates the effect of diet on long-term health and over 6,000 participants have been examined to date. The eye module is a key component of this study. UK Biobank Eye Study We are responsible for the eye component of the nationwide UK Biobank project, which aims to shed light on many of the most common debilitating diseases by studying genetic and molecular information from samples obtained from over 100,000 people around the UK. Impact of glaucoma on the individual This important field of research provides insight into how vision impairment caused by glaucoma impacts on the patient’s daily activities. We aim to determine the effect of binocular visual field damage (taken from both eyes) on daily activities (driving, mobility, reading, everyday tasks, face recognition). We have already shown how everyday tasks like reaching and grasping are affected by glaucoma. Future work will look at balance; we know that glaucoma is related to an increased risk of falling over, which can lead to fractures – a major health problem. 11 Ocular repair, regeneration and pharmaceutics Work within this theme includes new surgical techniques to improve surgery based on basic laboratory understanding of biological responses; the role of growth factors and their effect on ocular scarring; the cellular and molecular basis of cell motility (spontaneous movement) and scarring; and ocular stem cells – basic biology and therapeutic use including prevention of scarring, tissue reconstruction and regeneration. Why scarring is important Our focus is the efficient development of new clinical treatments to control scarring (fibrosis) after surgery and disease. The causes of fibrosis are complex and contribute to many human diseases, including every major blinding disease. There is a large unmet need for anti-scarring therapies that can be used for disease treatment and to manage healing after surgery. Preventing scarring also helps the body to regenerate, and encourages stem cells to restore the eye. Improving anti-scarring treatments Administration of anti-cancer agents directly into the eye after glaucoma filtration surgery to control fibrosis, and therefore manage healing, is currently the best clinical treatment available. There are many side effects because repeat injections of high doses that are naturally and 12 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Professor Peng Tee Khaw Theme leader – Ocular repair, regeneration and pharmaceutics Professor of Glaucoma and Ocular Healing at UCL Institute of Ophthalmology and consultant ophthalmic surgeon at Moorfields Eye Hospital rapidly cleared in some regions of the eye (eg the conjunctiva) are nevertheless toxic locally and systemically. To address toxicity, we have discovered that repeat injections of a drug called metalloprotease inhibitor (MMPI) have a markedly beneficial effect on scarring reduction without the toxicity of anti-cancer agents. “Research has, so far, saved my sight. It could help me and many other children in the future.” Rhiannon Willis, Moorfields patient “Rhiannon’s story shows how research really changes lives. She lost her sight from inflammation and scarring but we managed to restore her sight using new techniques and treatments developed through research. Her story inspired most of the donations for the new children’s hospital, and she fittingly laid the foundation stone.” Peng Khaw Above left: The size of the tissue tablet relative to a pound coin You can see Rhiannon’s story at http://www.nihr.ac.uk/ about/Pages/about_ transforming_health_ research_video.aspx New methods of drug delivery “The NIHR has helped to bring scientists like To address tissue-specific pharmacokinetics me together with clinicians to help change lives.

Our results support a clear pathway to develop Professor Steve Brocchini, Professor of Chemical the MMPI tablet to treat post-surgical fibrosis that Pharmaceutics at the School of Pharmacy in has a very good chance of success. If post-surgical London, and a major researcher in the ocular scarring can be controlled and the surgery is repair, regeneration and pharmaceutics theme successful long term, we have shown in large trials that it is possible to halt the progression of glaucoma. We have also developed a prolonged dosage form of an antibody, a protein-based medicine. Antibodies are usually administered as injections, but we have developed a tablet form, whereby a single tablet can be placed at the site of surgery, and remain biologically active over an extended period of time. A recent study has shown this new antibody tissue tablet to be more efficacious than any treatment now used clinically. Since glaucoma is the second leading cause of blindness worldwide, the development of these new medicines will allow simplification during surgery and in post-surgical procedures. This will potentially allow glaucoma filtration surgery to be conducted more widely to halt progression of glaucoma in a greater number of patients. Peng Khaw examining a young patient’s eye prior to surgery 13 Ocular surface disease Ocular surface diseases include several blinding disorders that affect the cornea and conjunctiva at the front surface of the eye. As a national referral centre, Moorfields has relatively large numbers of patients whose ocular surface disease is so severe that they have lost their sight. Much of our time in clinics and operating theatres is spent treating these patients with immunosuppressive drug treatment, or corneal or stem cell transplantation. We are focussing on three areas of translational research that will lead to new treatments for patients with ocular surface diseases. Direct molecular quality enhancement of donor corneas We aim to prolong the lifespan of donor cornea cells following transplantation in patients with blinding corneal disease (about 500 corneal transplants are undertaken in Moorfields each year). We are developing a method to do this by modifying donor cornea cells in the laboratory before transplanting them into patients’ eyes. This should reduce – and possibly remove – the need to replace transplants and, in the future, the need for a transplant may be eliminated altogether by treating the patient’s own cornea with this type of technique. 14 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today MR Frank Larkin Theme leader – Ocular surface disease Consultant ophthalmic surgeon at Moorfields Eye Hospital and senior lecturer at both UCL Institute of Ophthalmology and at Imperial College School of Medicine at Hammersmith Hospital Stem cell transplantation for limbal failure The Cells for Sight Transplantation and Research Programme is at the forefront of using stem cells to tackle eye diseases that were previously untreatable. Where previously permanent blindness occurred, we can now help some patients with genetic disorders, eye inflammation or chemical burns who have scarring and opacity of the cornea. We are developing the optimum process to provide a graft with the highest possible stem cell content. Successfully transferring such The Cells for Sight Transplantation and Research Programme Dr Julie Daniels directs the Cells for Sight Transplantation and Research Programme and is the scientific lead for ocular surface stem cell therapy at the NIHR BRC for Ophthalmology. In 2004, the Cells for Sight Tissue Bank was the first stem cell bank in the UK to obtain approval from the MHRA to treat patients with cultured stem cells (stem cells grown in the laboratory). Around 60% of the patients treated have experienced improved vision and reduced pain. This year, a new, expanded state-ofthe-art stem cell therapy research unit will be opened. This unit will not only continue to provide therapy for ocular surface disease but will also support clinical trials of stem cell-based therapies for other blinding eye diseases, including macular degeneration and possibly optic nerve repair. a graft from the laboratory to the surface of a means that if we have innovative treatments to patient’s eye in the operating theatre has been an translate from the laboratory to patient care, we obstacle that we are overcoming by developing a can research their effectiveness fairly quickly.

Thus we have quite large numbers of such patients: this Christina, Moorfields patient 15 Paediatrics and inherited eye disease Inherited disorders of the retina are one of the leading causes of childhood blindness and for the most part there are no effective treatments. Loss of vision is caused by the gradual death of the light-sensitive cells in the retina. We are investigating several different approaches to developing effective treatments. Gene therapy for childhood blindness professor Anthony Moore First, a group led by Professor Robin Ali are trying Theme leader – Paediatrics and to improve the function of the light-sensitive cells and inherited eye disease prevent their death using gene therapy – the introduction of a normal copy of the gene into the Duke Elder Professor of Ophthalmology at UCL retina to replace the faulty gene. This new human Institute of Ophthalmology and consultant gene is inserted into a harmless virus which then ophthalmologist at Moorfields Eye Hospital and transports the gene into the retinal cells, where the Great Ormond Street Hospital for Sick Children gene is able to function normally. In 2008 we performed the first gene therapy clinical trial for noticed a significant improvement in his night-time retinal disease in man, treating a rare form of vision.

Whether I’ll be able to do it or not, I don’t know, but I’m relying on these scientists.” Moorfields patient involved in the retinal implant trial Above left: The Argus II retinal implant in situ Artificial retina A second approach is to replace the retinal cells that have died. This requires a source of healthy retinal cells but this is currently not available. We have a team of scientists working towards developing retinal cells from human stem cells. This is a complex process, but we have made major advances over the last few years and this form of treatment is a realistic possibility within the next five years. When the light-sensitive cells in the retina have died completely, the retina fails to function and the patient is blind, even though the nerves that transmit information from the eye to the visual part of the brain still work. This has led to the idea of developing an artificial retina that will stimulate the nerves within the eye directly and convey visual information to the brain. Moorfields is one of a few centres internationally involved in a multicentre clinical trial of one form of retinal implant, the Argus II retinal implant. Since 2008 our surgeons, led by Mr Lyndon da Cruz, have carried out seven successful operations to insert the Argus II retinal implant into the eyes of seven blind patients suffering from severe retinitis pigmentosa. The Argus II system uses a spectacle-mounted camera to feed visual information to electrodes in the eye. The electrical pulses emitted induce responses in the retina that travel to the brain via the optic nerve. The brain is then able to perceive patterns of light and dark spots corresponding to the electrodes stimulated, and the implants generate consistent visual perceptions for the patients. The early results of the trial are very promising. As the technology improves, the next generation of these retinal implants will revolutionise the treatment of patients who are blind due to retinal disease. Genetics of human retinal disease Another aspect of research within the theme is to identify the specific genetic changes causing retinal disease within families, and then to carry out detailed investigation of retinal function using electrophysiology and psychophysics and correlate this with the structure of the retina. We have access to state-of-the-art imaging, so it is now possible to image the different layers of the retina and even the light-sensitive cells themselves. We use the same approach to study the effects of novel therapies such as gene therapy. The testing and imaging of young children is especially challenging. Young patients cannot follow instructions or sit patiently through long testing sessions, so we need to use specially developed child-friendly methods to measure their vision accurately. We have recently recruited a new research group, led by Dr Marko Nardini, who have expertise in measuring vision in infants and young children. They are developing novel methods of testing using state-of-the-art ‘eye tracking’ equipment that records where on a screen the child is looking. By displaying specially designed patterns and measuring the child’s eye movements towards them, we can test how well children can see. These methods work even with very young infants. 17 Infrastructure support The presence of an integrated, comprehensive set of support facilities is critical to our success. The following facilities enable all our discoveries, progress and achievements. Gene therapeutics Eye bank The BRC programme of research has provided infrastructure support, such as a Vector Core Facility, and focus groups for researchers investigating the genetic causes of blinding eye diseases. Donations by members of the public of human tissue to researchers to facilitate the development of new approaches in the treatment of blinding eye diseases. Genotyping and phenotyping facility Technical and senior research support in genotyping and phenotyping to underpin the research conducted by all research themes. Imaging and psychophysics Combining the expertise of optometrists, senior academic psychophysics researchers and senior NHS clinicians. Imaging takes a number of forms, of which microperimetry is just one. Cells for Sight Tissue Bank A facility for the development of limbal epithelial stem cell transplantation in patients with blinding ocular surface failure. 18 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Microperimetry allows us to map visual sensitivity by displaying small spots of light at precise locations on the retina. This allows us to track the progression of the patient’s vision loss, and to map any improvements in visual sensitivity following new treatments. Ocular electrophysiology Expertise underpinning the assessment of patients who have been treated with novel therapies. NIHR Research and Treatment Centre for Eyes and Vision This centre is being developed as part of the BRC to include expanded phenotyping facilities, advanced imaging, a novel treatments unit, and functional vision assessment before and after administration of novel therapies. This new centre has quadrupled our existing clinical research area. Joint strategic infrastructure and management Reading Centre Image grading to identify eye disease pathology and progression and development of novel research methods. The BRC supports the continued integration and development of strategic and research support systems across the whole site to facilitate the development of better patient management. The Richard Desmond Children’s Eye Centre at Moorfields The Richard Desmond Children’s Eye Centre at Moorfields houses the Fight For Sight paediatric research floor. Moorfields Pharmaceuticals Development of new pharmaceutical approaches to the treatment of disease including delivery of new medicines to patients. 19 Education and training Training future leaders in academic medicine. We fully support the tenets established by the NIHR Trainees Coordinating Centre (TCC), which means that we seek ways of developing research careers and research leaders whose work focusses on people and patient-based applied health research. Clinical lecturers We have six NIHR Integrated Academic Training (IAT) clinical lecturers on our joint site. These new posts, introduced through the NIHR TCC, represent a significant investment by the NIHR and the London Deanery in securing our future leaders in clinical academic ophthalmology. Clinical lectureships are specialty training posts that incorporate research with clinical specialty training. These posts are aimed at doctors who have completed a research doctorate or equivalent and show outstanding potential for continuing a career in academic medicine or dentistry. Mr Rizwan Malik, clinical lecturer in Ophthalmic Translational Research “I am immensely fortunate to have the opportunity to pursue an academic career in ophthalmology as an NIHR clinical lecturer; such opportunities were not available to my predecessors just a few years ago. The joint set-up of a premier research institution and world-class clinical establishment makes the BRC an unrivalled place to undertake translational research. The foundation of this research is underpinned by a patient-centred approach: the research needs are identified by potential areas of improved clinical care whilst the outcomes are designed to have a measurable impact on the lives of the patients we treat.” Rizwan Malik Alongside our clinical lecturers we are very fortunate to have a strong base of clinical research fellows and associates, post-doctoral research associates, research fellows, clinical research optometrists, PhD and MD students, research orthoptists, technicians, and genetic nurses and counsellors. 20 Director of Education, UCL Partners Eyes and Vision Theme Professor Peter Shah has taken up the role of Director of Education, UCL Partners (UCLP) Eyes and Vision Theme, for which he is based part-time at the NIHR BRC for Ophthalmology. Peter is a consultant ophthalmic surgeon and the Supra-regional Glaucoma Specialist at University Hospital Birmingham NHS Trust, where he continues his clinical work. “I passionately believe that education is one of the key drivers for clinical excellence, and is the gear which allows us to translate research and innovation into improved care for the diverse communities we serve.” Peter Shah Peter and his team will be working hard to make UCLP Eyes and Vision the recognised world leader for ophthalmic education, focussing on clinical excellence and patient safety, and strengthening the learning culture throughout the organisation. Integration of the NIHR BRC with UCL Partners academic health science centre strategy Using the impetus provided by the tenets of the academic health science centre, Peter will be responsible for delivering a new MSc programme at the heart of the community for health science professionals, such as optometrists and community nurses, including communicating research developments, trials information and new technologies, with a particular interest in deprived communities. He will also be looking into ways of developing new courses for clinical ophthalmologists, incorporating clinical practice and research development. A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Our successes at the 2010 NIHR Experimental Medicine Summer School Miss Megan James, PhD student, is pictured here with Professor Dame Sally Davies, Director General for Research and Development at the Department of Health, receiving an award for best poster presentation for her work on ‘Optimisation of Cellular Scaffolds for Neural Retinal Cell Replacement using Human Muller Stem Cells’. The summer school was open only to doctoral students nominated by all 12 national Biomedical Research Centres. Seventy delegates attended the event and all submitted an abstract for oral or poster presentations. Of those only three were selected to present orally and 25 by poster. Dr Clemens Lange, one of our clinical research associates, and a PhD student, is seen here presenting his work on ‘Intraocular Oxygen Distribution in Advanced Proliferative Diabetic Retinopathy’, for which he received a ‘highly commended’ award for his oral presentation. “As a graduate student involved in translational research at the NIHR BRC for Ophthalmology, I am grateful for the support I receive from the NIHR, without which I would not be able to carry out research towards my PhD. To work in an environment where science and clinical practice are so intertwined is truly inspirational, and this has led me to consider applying for a medical school place in the future.” Megan James “The NIHR supports me to work with outstanding scientists and clinicians, in world-class facilities, to conduct leading-edge research focussed on the needs of patients. Working within the NIHR BRC for Ophthalmology provides an ideal opportunity for people with an interest in translational research and has reinforced my goal to pursue a career as a clinician scientist.” Clemens Lange 21 Patient and public involvement Our patients help us to determine the important questions that need to be answered through research, and increasing numbers of patients are becoming involved in the design of research trials. We are also organising more combined patient/researcher days, which we have found to be remarkably mutually beneficial. Recent examples include ‘Glaucoma, Genes and Me’, and the ‘Birdshot Patient Day’. Events Glaucoma, Genes and Me Since 2006, Mr Paul Foster and Dr Sancy Low have been involved in a research project looking at the genes involved in or responsible for primary angle-closure glaucoma (PACG). Over 80 families from the UK were involved in their project. In September 2009, we held an event in central London to bring together the research participants, genealogy volunteers, charitable sponsors and experts in the field of PACG. We were supported by UCL under the Beacons for Public Engagement programme - funded by the UK Higher Education Funding Councils, Research Councils UK and the Wellcome Trust. This event was a superb opportunity to discuss topics related to angle-closure glaucoma, and the PACG patients and their families were able to gain information on the aspects of PACG that were most important to them. As researchers, we benefited from gaining insights from patients about how best to communicate with the public about disease and research. “The feedback we received was exceptionally positive and participants indicated great enthusiasm for more events of this nature.” Dr Sancy Low 22 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today Participants in our ‘Glaucoma, Genes and Me’ event Birdshot Patient Day In September 2010, after months of careful planning, we held a patient day for sufferers of Birdshot Chorioretinopathy. Birdshot is an autoimmune disease, a rare and chronic form of posterior uveitis that is potentially blinding, particularly if left untreated. We worked with the Birdshot Uveitis Society to make this event possible and were again supported by UCL under the Beacons for Public Engagement programme. The Birdshot Patient Day provided an opportunity for people to meet fellow sufferers who understand the difficulties of living with this disease, talk to the experts, hear about innovations in treatment, and to know that there is a strong support network available to them. Clinical researchers were able to discuss treatment regimens with patients, and current research into the disease. Through these discussions, patients identified issues that are of key importance to them, which will inform the development of research proposals in the future. “ I am no longer scared of my future and I feel less isolated and powerless.” Patients and staff at our Birdshot Patient Day – an opportunity for all to learn more Rea Mattocks, Birdshot patient, co-founder of Birdshot Uveitis Society and co-organiser of the Birdshot Day 23 24 A Vision for Vision Making tomorrow’s sight-saving treatments a reality today New tests are being developed to measure vision in infants and children using specially designed displays and an ‘eye-tracker’ device that measures where on the display the child is looking.
