What is Convergence Insufficiency?
Under normal circumstances the eye muscles will pull both eyes inwards towards the nose
smoothly when looking at an object close up. Normally this occurs without effort and
allows comfortable use of binocular (both eyes) vision whilst reading or doing other close
work. Weakness of these eye muscles may cause problems in co-ordinating the eyes at
close range – this is called Convergence Insufficiency.
What Causes Convergence Insufficiency?
There are many different causes but the possibilities include a change of occupation
involving increased close work, an intensive period of close work (e.g. studying for exams),
over work, worry, recent illness or whiplash. Sometimes no reason is found.
What symptoms does Convergence Insufficiency cause?
Typical symptoms are headaches in the front of the head and around the eyes, eye strain
and sometimes difficulty in changing focus from distance to near. Blurred vision or double
vision may also be noticed
What treatment is available?
Normally eye exercises, which can be practiced at home, will be recommended. If
exercises are carried out regularly, improvement is usually quite rapid and within a few
weeks symptoms should improve. Some people do need longer to improve and may take
several months to get completely better. The eye exercises will be supervised by an
Orthoptist, who is a specialist in eye muscle balance and co-ordination. The Orthoptist will
explain which exercises are best for each individual patient and explain how to carry them
out. Advice will be given on the frequency and duration of the exercises and a follow-up
appointment will be arranged. It is important to attend the follow-up appointment to check
on progress and to change the exercises if necessary.
What will happen if the symptoms are not cured by exercises?
The Orthoptist will probably recommend further tests with an Ophthalmologist to determine
if there is any other cause of the symptoms.
Exercises explained
Convergence to a pen
It is probably best to get somebody to read these instructions to you as you do the
exercise.
These are basic instructions and variations on these, may be given by the Orthoptist,
tailored to your needs.
You may be advised to use a pen or sometimes a small picture or piece of reading print
attached to a small wooden stick. For the purposes of these instructions a pen is
described but the principles are the same whatever target is used.

•
With your head straight, start with the pen at arms length, straight ahead and at eyelevel or slightly below eye-level. Focus on the tip of the pen and make sure it is single
and clear. Move the pen slowly towards your nose making sure that the pen stays
single for as long as possible.
•
If the pen goes double (i.e. you see 2 pens) stop moving the pen immediately but
continue to look at it and use your eye muscles to “pull” the images together to make
one pen again. Do not do this by closing one eye, by blinking or by looking away from
the pen, as this will not exercise the muscles. The sensation you will feel is one of
going cross – eyed; do not worry, this is normal and is necessary to achieve results. If
you can make the stationery pen single again by pulling your eyes in then start to
slowly move the pen towards you until it doubles up again. Repeat the process of
stopping, trying to use your eyes to make the pen single again and then proceeding as
before.
•
If you can only move the pen in towards your nose so far before it goes double, and if
you are unable to make it single again despite trying hard to do so, try taking the pen
back a short distance (2 or 3 centimeters) away from the nose and try again. Do not go
right back to the beginning each time the pen doubles up. You need to work hard
around the area where the pen starts to go double – this will improve your convergence
insufficiency.
The aim of the exercises is to be able to watch the pen move slowly all the way to the end
of your nose and to keep it single all the way. The closer you get towards your nose the
harder the exercise will become.
If you are in any doubt about the pen convergence exercises, ask the Orthoptist to
demonstrate it to you at your next visit.
Incidentally, if whilst doing this exercise you happen to notice that you can see double of
other objects in front of or behind the pen, do not worry. This is a normal phenomenon
called physiological diplopia, just ignore it.
The Orthoptist will advise you how frequently and for how long to do this exercise.
The Dot Card
Home Exercises to improve Convergence Insufficiency
Page 3 of 8
•
These are double-sided dot/letter cards for measuring the near point of convergence
and of accommodation and for home exercises.
•
Dot cards treat convergence insufficiency more effectively than simple pen push-up
exercises by ensuring correct ocular alignment.
•
Dots are placed at 3cm intervals along the card, which is held lengthwise touching the
end of the nose so that the dots are 6cm to 24cm from the eye. Clear instructions are
included, but additional information for correct treatment of convergence insufficiency
should be given by a qualified practitioner.
•
Keep your head straight, hold one end of the dot card against the tip of your nose.
Hold the card straight or angled slightly downwards in a position where you can see all
the dots properly.
•
Look at the furthest dot and try to make your eyes see this as one (i.e. singly) by gently
using the eye muscles to pull the eyes inwards.
•
When you see this furthest dot singly, all the other dots should appear double and they
will fan outwards towards you. This is normal.
•
If you can make the furthest dot single, count up to 10 slowly whilst keeping the dot
single.
•
Once you are able to do this look at the next dot up the line closer to you and do the
same. Make it single by gently pulling inwards with the eye muscles.
•
When this dot appears single all the other dots should appear double – making an X
pattern crossing through the dot you are looking at. This is normal. Again hold this
position, keeping the dot single, for a short count of 10 (slowly).
•
Continue in the same way up the line of dots towards you making sure each one is
single and holding each one for a count of 10. If you cannot make a dot single go back
to the previous dot and try again. If you are unable to make even the furthest dot single
it may be that this exercise is too advanced for you at this stage in which case the
Orthoptist will advise you. However some people do find this exercise difficult at first
so do persevere.
Make sure you make a conscious effort to pull your eyes in to look at the dots – the
sensation is one of going “cross eyed”. Sometimes discomfort is felt during the exercises.
This is normal and it is necessary to keep exercising despite this discomfort but the
exercise should not cause actual pain or bring on a headache – consult the Orthoptist if
this happens.
If you can only get a short way down the dots but no further – keep practicing!

Take each dot in turn slowly and do not proceed to the next dot until you are able to hold
the previous one single for a count of 10. The aim of the exercise is to be able to see the
dot closest to your nose singly and hold it for a count of 10.
The Orthoptist will advise you how often to do this exercise and will tell you about
relaxing your eyes after exercising.
Relaxation
It is extremely important to relax the eye muscles properly following exercising. This will
avoid problems such as convergence spasm which can occur in very rare cases if some of
the eye muscles do not relax sufficiently.
The eyes may feel uncomfortable following exercising and this is to be expected but too
much exercising and/or not enough relaxation may make the eyes feel more
uncomfortable than is necessary.
Do not practice for longer periods than advised by the Orthoptist and try to avoid
exercising when your eyes are particularly tired or you are unwell.
After the exercises make sure you either close your eyes for one minute or look far into the
distance (e.g. out of the window) for a minute before undertaking any other activity. This is
as important as doing the exercises themselves.
Always follow the instructions carefully and ask if you are unsure about anything.

Research
Research is undertaken to add to the existing scientific knowledge on a particular subject.
There are a number of staff within the Trust who conduct Research studies. It is possible that
during the course of your treatment you may be asked to take part in a research study,
however, you do have the right to refuse, and this will not affect the care that you receive.
Your NHS Number, Keep it Safe
Every person registered with the NHS in England and Wales has their own
unique NHS Number. It is made up of 10 digits for example 123 456 7890.
Everyone needs to use the NHS Number to identify you correctly. It is an important step
towards improving the safety of your healthcare.
Always bring your NHS number with you to all hospital appointments or quote it if you need to
telephone the hospital for any enquires. This will allow staff to check that they have the right
patient details by checking this against your NHS number.
To improve safety always check your NHS Number on correspondence the NHS sends to you.
Ways of finding out your NHS Number
If you do not know your NHS number you can contact your GP Practice. You may be asked
for proof of your identity, for example a passport or other form of identity, this is to protect your
privacy. Once you have obtained your NHS Number write it down and Keep it Safe.

Stop Smoking Support
A visit to hospital is very often the trigger for many people to quit smoking, and we know that
70% of people that smoke would like to quit. The Trust is a smoke free area and smoking is
prohibited in all buildings, grounds and car parks.
For patients wishing to quit smoking following their admission to hospital, or if patients simply
require support during their hospital stay, there is a designated specialist Stop Smoking Team
available.
Patients that aren’t staying in hospital or are planning to quit ahead of their hospital stay can
also access specialist support. The Wigan Stop Smoking Service community team provides
support across the borough. You can call us on 01942 482539 or free on 0500 7867 669 to
speak to a member of the team or visit www.alwch.nhs.uk/stopsmoking for further information.
