KNOW MORE ABOUT SQUINT
When a car loses its alignment it does not run properly in straight direction isn’t it?
The same happens with eyes, when there is misalignment in two eyes, the both eyes cannot look in same direction and that is known as
This alignment may get disturb constantly or only for some-time in a day. It is common in children but may occurs in adults.
When eyes are not aligned properly each eye focus on different object and brain gets two different signals leading to confusion and may have these effects:
1. A child may ignore the image coming from the deviated eye and thus sees only one image, this suppression of image from deviated eye result in poor development of vision in this eye which is called as Amblyopia.
2. An adult has double vision, Diplopia because he can not ignore the image.
Squint can be classified as following
A) Depends upon angle/ degree of severity
1. Concomitant squint — Angle of squint is same in all direction that you look. The two eyes move well, all muscles are working, only alignment is missing.
2. Incomitant squint: The angle may vary when you look to left there may be no squint and eyes are aligned.
B) By the direction of turning eye-
1. Inward [Esotropia]
2. Outward [Exotropia]
3. Upward [Hypertropia]
4. Downward [Hypotropia].
C) 1. Constant 2. Intermittent
D) 1. Manifest Squint: Eye turn when open.
2. Latent Squint Eye turn when shut.
E) Childhood Squint: Squint is common in first 3 years of life. In many cases of childhood squint, the reason is not known. In some cases the disorder of eye muscles, eyes, brain or nerves are there.
Causes: The movement of each eye is controlled by six muscles– That pull eye in various direction. They are Superior, Inferior, Medial, Lateral Muscles and Superior and Inferior Oblique Muscles. Squint develops when these muscles do not work in a balanced way.
