You must practice easy exercises for your eyecare. To remove convergence insufficiency there are many easy exercises available, explained in the article.
What is Convergence Insufficiency?
Convergence Insufficiency (CI) is characterized by a decreased ability to converge the eyes and maintain binocular fusion while focusing on a near target. CI is usually accompanied by a reduced near point of convergence (NPC), decreased convergence amplitudes or an exodeviation at near. Convergence insufficiency (CI) is an eye disorder where your eyes don’t move at the same time. If you have this condition, one or both eyes move outward when you look at a nearby object. This can cause eyestrain, headaches, or vision problems like blurred or double vision. It also makes it hard to read and focus. This condition also causes one eye to turn outward instead of inward with the other eye creating double or blurred vision.
Who gets Convergence Insufficiency?
Convergence insufficiency is usually diagnosed in school-age children and adolescents. It can cause difficulty in reading. Convergence Insufficiency is a common eye condition in both children and adults. We do know that between 4 and 17 percent of children and adults are thought to have CI. While CI usually begins in childhood, it can begin at any age, and without treatment CI can persist for many years. Recent studies have found that CI is very common after concussions that do not resolve in a few weeks.
What causes Convergence Insufficiency?
The cause of convergence insufficiency isn’t known, but it involves a misalignment of the eyes when focusing on nearby objects. The misalignment involves the muscles that move the eye. Typically, one eye drifts outward when you’re focusing on a word or object at close range. Convergence insufficiency can arise following infection, traumatic brain injury, certain medications, neurodegenerative diseases, myasthenia gravis, or Graves ophthalmopathy.
Exercises to cure Convergence Insufficiency:
If convergence insufficiency isn’t causing symptoms, you generally don’t need treatment. But for people with symptoms, treatment with eye-focusing exercises can increase the eyes’ convergence ability. Normally eye exercises, which can be practiced at home, are 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.
Convergence to a Pen
- With your head straight, start with the pen at arm’s length, straight ahead and at eye-level 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.
- Hold the pen at arm’s length and look at your distance fixation point.
- Then quickly “jump” your fixation to look at the pen and make the pen single. If the pen is double “pull your eyes in” to make it single again.
- Once it is single “jump your fixation back to the distance target.
- When you can do this with ease move the pen in slightly.
- Re-fix in the distance and Jump your fixation back to the pen.
- Continue to do this until the pen is almost touching your nose.
The Dot card
The aim of the easy exercises is to improve your ability to pull your eyes inwards towards each other by maintaining a single image of each dot on the card (or letter on the reverse of the card).
- Hold the card lengthways so that it is touching the end of you nose with the line of dots infront of you.
- Look at the furthest dot. If your eyes are converging correctly the viewed dot will be singular and the other dots will be seen in an A shape (see diagram 1)
- Shift your eyes to the second dot. If the eyes are still converging correctly this second dot will now appear single and the other dots will be seen in an X shape.
- Each dot should be held as a single image for the count of 5 before moving to the next dot.
- If you are having difficulty forming a single dot or unable to hold a dot singular for the count of 5, move to the previous dot and try again. Extra dots can be added between the original dots on the card if necessary.
- Once the dot nearest your nose has been reached and held as a single image, the dots behind will appear double and will form a V shape.
A stereogram is a card that consists of two similar images that are separated on the horizontal axis. The patient then converges their eyes to an area in front of the card in order to elicit physiological diplopia. If the patient is successful then a third image will appear in the middle of the two pictures on the card. The middle image is actually a superimposed, combined image of the two pictures.
- Hold the stereogram at arm’s length and hold a pen in front of the card.
- Concentrate on the tip of the pen.
- Slowly move the pen towards you.
- Watch the pen tip all the time but be aware of the 2 stereogram pictures in the background.
- As the pen moves the stereogram, images should each appear to split apart.
- When the pen is positioned approximately half way towards your nose, the 2 split images should appear to overlap to form a 3rd image.
Voluntary convergence :
When convergence has improved, your doctor may ask you to try this, convergence without the aid of a near target. You can do this by following a near target in towards your nose and when the target is removed, try to keep your eyes in a convergent position i.e. cross your eyes. The aim is to be able to converge without a target as a stimulus.
In this exercise, you focus on a small letter on the side of a pencil as you move it closer to the bridge of your nose, stopping as soon as you see double. The easy exercises is often done for 15 minutes a day, five or more days a week.
Computer vision therapy.
Eye-focusing exercises are done on a computer using software designed to improve convergence. You can print the results to share with your eye doctor.
Glasses with built-in prisms generally haven’t proved effective. If you have another focusing or vision problem, such as not seeing well close up (farsightedness), reading glasses might help.
