RVO is an obstruction of one of the veins
that drains blood away from the retina
• The type of RVO depends on the location of the occlusion1

RVO is a major cause of vision loss
• RVO is the second most common sight-threatening
retinal vascular disorder (after diabetic retinopathy)1
– RVO is unilateral in most patients2
– Can be severe2
 Possible loss of vision to below driving standards3
 As a result, most patients are willing to undergo
invasive treatments1
• Sign of possible underlying systemic pathology2
RVO = retinal vein occlusion.

Background and epidemiology: Summary
• BRVO is an occlusion of a branch retinal vein
• Main vision-threatening complications are macular oedema,
retinal ischaemia, and neovascularisation and its sequelae
• Impact on vision depends on the location of the occlusion
• BRVO can be classified as ischaemic or non-ischaemic
• Incidence of BRVO is 1.2–1.8%
– Patients are predominantly over the age of 55 years, but BRVO
also affects the working-age population
– There are no specific data for the UK

BRVO is considered to be the result of compression
of a vein at an arteriovenous crossing
• The following features of
arteriovenous crossings
contribute to the risk of
venous occlusion:
– Artery and vein share a
common adventitial sheath1
– The artery lies anterior to
the affected vein in 99%
of eyes with BRVO2
• More than half of BRVO cases
occur in the superotemporal
quadrant3

Pathophysiology: Summary
• BRVO is considered to be the result of mechanical narrowing of a
branch retinal vein lumen at an arteriovenous crossing
• Thrombus formation, as a result of Virchow’s triad, causes venous
occlusion
– Resulting occlusion leads to increased intraluminal pressure,
retinal ischaemia, upregulation of inflammatory cytokines
(including VEGF), vascular permeability and angiogenesis
• The resulting haemorrhage, neovascularisation, and macular
oedema may all lead to vision loss, the main symptom in BRVO

Collateral blood vessels form
in long-standing BRVO1
•
Compensatory blood vessels open up
in long-standing BRVO1
– Bypass the occlusion, diverting blood
to a non-occluded vessel
– Seen as a positive development
•
Differ from vessels formed as a result
of neovascularisation:1
– Originate from capillaries and join
obstructed and non-obstructed vessels
– Do not usually leak on FA
•
Development appears to be independent
of VEGF,2 hence anti-VEGF therapy is
unlikely to impede their development

GENEVA: Summary
• GENEVA compared DEX intravitreal implant 0.7 mg and
0.35 mg with sham for the treatment of macular oedema
secondary to BRVO and CRVO
• A significantly greater proportion of BRVO patients
gained ≥15 letters with DEX (0.35 mg and 0.7 mg)
versus sham at days 30, 60, and 90
– However, this difference was not maintained to day 180
• At day 180, incidence of ocular AEs was higher in BRVO
patients in the DEX groups (0.7 mg and 0.35 mg) versus
sham
• Repeat dosing with DEX increased cataract formation

Intravitreal anti-VEGF therapies block the actions
of VEGF to alleviate symptoms of BRVO
Side effects3,4
Mechanism
Anti-VEGF therapies when injected into
the eye block the actions of VEGF. This
reduces vascular leakage and macular
oedema and inhibits the growth of the
blood vessels located within the eye1,2

Systemic side effects:
• Nasopharyngitis, hypertension
Ocular side effects:

BRAVO-HORIZON-RETAIN: Summary
•
The BRAVO-HORIZON-RETAIN trials aimed to assess the efficacy of
ranibizumab for the treatment of macular oedema secondary to BRVO
•
Ranibizumab rapidly and significantly improved BCVA and CRT versus
sham at month 12
– These results were maintained to month 24
•
Only 9% of the BRAVO population entered RETAIN
– No firm conclusions can be made on the long-term efficacy of ranibizumab
•
For some patients, BRVO is a chronic condition requiring long-term
treatment
– 50% of patients still required treatment at mean follow-up 50.3 months
•
No new safety events occurred with the long-term use
of ranibizumab

VIBRANT: Summary
•
The first Phase III trial to compare an anti-VEGF agent with the prior
standard of care (macular grid laser photocoagulation therapy) in BRVO
•
Patients were randomised to aflibercept 2q4 or laser
– At week 24, patients in the aflibercept group were switched to 2q8 regimen
•
A significantly higher proportion of patients taking aflibercept gained ≥15
ETDRS letters from baseline at week 24 (primary outcome) and at week 52,
when compared with patients receiving laser therapy
•
Mean CRT reductions from baseline to week 24 and week 52 were
significantly greater in the aflibercept arm vs laser arm
•
Aflibercept is well tolerated in the treatment of visual impairment due to
macular oedema secondary to BRVO
August 2016
UKEYL08160072
118
Posology of aflibercept for RVO (BRVO or CRVO)1
•
After the initial injection, treatment is given monthly. The interval between two doses should not be shorter than
one month.
•
If visual and anatomic outcomes indicate that the patient is not benefiting from continued treatment, Eylea should
be discontinued.
•
Monthly treatment continues until maximum visual acuity is achieved and/or there are no signs of disease activity.
Three or more consecutive, monthly injections may be needed.
•
Treatment may then be continued with a treat-and-extend regimen with gradually increased treatment intervals to
maintain stable visual and/or anatomic outcomes, however there are insufficient data to conclude on the length of
these intervals. If visual and/or anatomic outcomes deteriorate, the treatment interval should be shortened
accordingly.
•
The monitoring and treatment schedule should be determined by the treating physician based on the individual
patient’s response.
•
Monitoring for disease activity may include clinical examination, functional testing or imaging techniques (e.g.
optical coherence tomography or fluorescein angiography).
Consecutive monthly dosing until
disease stability (≥3 injections)

Management of macular oedema: Summary
•
The efficacy of macular grid laser photocoagulation for the treatment of
macular oedema secondary to BRVO was demonstrated in BVOS
– Mechanism is not fully understood
•
Intravitreal corticosteroids downregulate cytokine expression to inhibit
vascular permeability
– Triamcinolone demonstrated similar benefits to grid laser, but was
associated with higher rates of adverse events
– DEX demonstrated short-term improvements in BCVA, but repeat
dosing increased cataract formation
•
Intravitreal anti-VEGF therapies block the actions of VEGF to alleviate
symptoms of BRVO
– Both ranibizumab and aflibercept are effective for the treatment of visual
impairment caused by macular oedema secondary to BRVO

Mechanism
• Neovascularisation secondary to BRVO
• Reduces risk of vitreous haemorrhage
• Standard of care for peripheral retinal
ischaemia based on Branch Vein Occlusion
Study1,2
• Reduces oxygen demand by destroying
photoreceptors within the retina3
• Hypoxia is corrected and production of
cytokines is normalised3

Prescribing information (1)
Eylea® 40 mg/ml solution for injection in a vial (aflibercept)
Prescribing Information
(Refer to full Summary of Product Characteristics (SmPC) before prescribing)
Presentation: 1 ml solution for injection contains 40 mg aflibercept. Each vial contains
100 microlitres, equivalent to 4 mg aflibercept. Indication(s): Treatment of neovascular
(wet) age-related macular degeneration (AMD), macular oedema secondary to retinal
vein occlusion (branch RVO or central RVO), visual impairment due to diabetic macular
oedema (DMO) in adults and visual impairment due to myopic choroidal
neovascularisation (myopic CNV). Posology & method of administration: For
intravitreal injection only. Must be administered according to medical standards and
applicable guidelines by a qualified physician experienced in administering intravitreal
injections. Each vial should only be used for the treatment of a single eye. The vial
contains more than the recommended dose of 2 mg. The extractable volume of the vial
(100 microlitres) is not to be used in total. The excess volume should be expelled
before injecting. Refer to SmPC for full details. Adults: The recommended dose is 2
mg aflibercept, equivalent to 50 microlitres. For wAMD treatment is initiated with one
injection per month for three consecutive doses, followed by one injection every two
months. No requirement for monitoring between injections. After the first 12 months of
treatment, and based on visual and/or anatomic outcomes, the treatment interval may
be extended such as with a treat-and-extend dosing regimen, where the treatment
intervals are gradually increased to maintain stable visual and/or anatomic outcomes;
however there are insufficient data to conclude on the length of these intervals. If visual
and/or anatomic outcomes deteriorate, the treatment interval should be shortened
accordingly. The schedule for monitoring should therefore be determined by treating
physician and may be more frequent than the schedule of injections. For RVO (branch
RVO or central RVO), after the initial injection, treatment is given monthly at intervals
not shorter than one month. Discontinue if visual and anatomic outcomes indicate that
the patient is not benefiting from continued treatment. Treat monthly until maximum
visual acuity and/or no signs of disease activity. Three or more consecutive, monthly
injections may be needed. Treatment may then be continued with a treat and extend
regimen with gradually increased treatment intervals to maintain stable visual and/or
anatomic outcomes, however there are insufficient data to conclude on the length of
these intervals. Shorten treatment intervals if visual and/or anatomic outcomes
deteriorate. The monitoring and treatment schedule should be determined by the
treating physician based on the individual patient’s response. For DMO, initiate
treatment with one injection/month for 5 consecutive doses, followed by one injection
every two months. No requirement for monitoring between injections. After the first 12
months of treatment, and based on visual and/or anatomic outcomes, the treatment
interval may be extended such as with a treat-and-extend dosing regimen, where the
treatment intervals are gradually increased to maintain stable visual and/or anatomic
outcomes; however there are insufficient data to conclude on the length of these
intervals. If visual and/or anatomic outcomes deteriorate, the treatment interval should
be shortened accordingly. The schedule for monitoring should therefore be determined
by the treating physician and may be more frequent than the schedule of injections. If
visual and anatomic outcomes indicate that the patient is not benefiting from continued
treatment, treatment should be discontinued. For myopic CNV, a single injection is to
be administered. Additional doses may be administered if visual and/or anatomic
outcomes indicate that the disease persists. Recurrences should be treated as a new
manifestation of the disease. The schedule for monitoring should be determined by the
treating physician. The interval between two doses should not be shorter than one
month. Hepatic and/or renal impairment: No specific studies have been conducted.
Available data do not suggest a need for a dose adjustment. Elderly population: No
special considerations are needed. Limited experience in those with DMO over 75
years old. Paediatric population: No data available. Contraindications:
Hypersensitivity to active substance or any excipient; active or suspected ocular or
periocular infection; active severe intraocular inflammation. Warnings & precautions:
As with other intravitreal therapies endophthalmitis has been reported. Aseptic injection
technique essential. Patients should be monitored during the week following the
injection to permit early treatment if an infection occurs. Patients must report any
symptoms of endophthalmitis without delay. Increases in intraocular pressure have
been seen within 60 minutes of intravitreal injection; special precaution is needed in
patients with poorly controlled glaucoma (do not inject while the intraocular pressure is
≥ 30 mmHg). Immediately after injection, monitor intraocular pressure and perfusion of
optic nerve head and manage appropriately. There is a potential for immunogenicity as
with other therapeutic proteins; patients should report any signs or symptoms of
intraocular inflammation e.g pain, photophobia or redness, which may be a clinical sign
of hypersensitivity. Systemic adverse events including non-ocular haemorrhages and
arterial thromboembolic events have been reported following intravitreal injection of
VEGF inhibitors. Safety and efficacy of concurrent use in both eyes have not been
systemically studied. No data is available on concomitant use of Eylea with other antiVEGF medicinal products (systemic or ocular). Caution in patients with risk factors for
development of retinal pigment epithelial tears including large and/or high pigment
epithelial retinal detachment. Withhold treatment in patients with: rhegmatogenous
retinal detachment or stage 3 or 4 macular holes; with retinal break and do not resume
treatment until the break is adequately repaired.

Prescribing information (2)
Withhold treatment and do not resume before next scheduled treatment if there is:
decrease in best-corrected visual acuity of ≥30 letters compared with the last
assessment; central foveal subretinal haemorrhage, or haemorrhage ≥50%, of total
lesion area. Do not treat in the 28 days prior to or following performed or planned
intraocular surgery. Eylea should not be used in pregnancy unless the potential benefit
outweighs the potential risk to the foetus. Women of childbearing potential have to use
effective contraception during treatment and for at least 3 months after the last
intravitreal injection. Populations with limited data: There is limited experience of
treatment with Eylea in patients with ischaemic, chronic RVO. In patients presenting
with clinical signs of irreversible ischaemic visual function loss, aflibercept treatment is
not recommended. There is limited experience in DMO due to type I diabetes or in
diabetic patients with an HbA1c over 12% or with proliferative diabetic retinopathy.
Eylea has not been studied in patients with active systemic infections, concurrent eye
conditions such as retinal detachment or macular hole, or in diabetic patients with
uncontrolled hypertension. This lack of information should be considered when treating
such patients. In myopic CNV there is no experience with Eylea in the treatment of
non-Asian patients, patients who have previously undergone treatment for myopic
CNV, and patients with extrafoveal lesions. Interactions: No available data. Fertility,
pregnancy & lactation: Not recommended during pregnancy unless potential benefit
outweighs potential risk to the foetus. No data available in pregnant women. Studies in
animals have shown embryo-foetal toxicity. Women of childbearing potential have to
use effective contraception during treatment and for at least 3 months after the last
injection. Not recommended during breastfeeding. Excretion in human milk: unknown.
Male and female fertility impairment seen in animal studies with high systemic
exposure not expected after ocular administration with very low systemic exposure.
Effects on ability to drive and use machines: Possible temporary visual
disturbances. Patients should not drive or use machines if vision inadequate.
Undesirable effects: Very common: Visual acuity reduced, conjunctival haemorrhage
(phase III studies: increased incidence in patients receiving anti-thrombotic agents),
eye pain. Common: retinal pigment epithelial tear, detachment of the retinal pigment
epithelium, retinal degeneration, vitreous haemorrhage, cataract (nuclear or
subcapsular), corneal abrasion or erosion, increased intraocular pressure, blurred
vision, vitreous floaters, vitreous detachment, injection site pain, foreign body sensation
in eyes, increased lacrimation, eyelid oedema, injection site haemorrhage, punctate
keratitis, conjunctival or ocular hyperaemia. Serious: cf. CI/W&P - in addition:
blindness, endophthalmitis, cataract traumatic, transient increased intraocular
pressure, vitreous detachment, retinal detachment or tear, hypersensitivity (during the
post-marketing period, reports of hypersensitivity included rash, pruritus, urticaria, and
isolated cases of severe anaphylactic/anaphylactoid reactions), vitreous haemorrhage,
cortical cataract, lenticular opacities, corneal epithelium defect/erosion, vitritis, uveitis,
iritis, iridocyclitis, anterior chamber flare, arterial thromboembolic events (ATEs) are
adverse events potentially related to systemic VEGF inhibition. There is a theoretical
risk of arterial thromboembolic events, including stroke and myocardial infarction,
following intravitreal use of VEGF inhibitors. Consult the SmPC in relation to other side
effects. Overdose: Monitor intraocular pressure and treat if required.
Incompatibilities: Do not mix with other medicinal products. Special Precautions for
Storage: Store in a refrigerator (2°C to 8°C). Do not freeze. Unopened vials may be
