Squint

☛ What is squint?

Squint otherwise called as strabismus is a condition in which there is misalignment of the eyes, due to which both eyes do not look in the same direction. The misalignment may be constant or it may appear only at times. Only one eye may be constantly misaligned or both eyes may misaligned alternatively. This disease is very common in children though it may occur in adults also.

 
☛ What causes squint?

The exact cause of squint is not known. Eye movement is controlled by six muscles attached on the outside of the eye which work in coordination. If there is any loss of coordination between the muscles, it will lead to misalignment.

Occasionally, a refractive error like hyperopia or high myopia or poor vision in the eye due to some other long standing eye disease like corneal opacity, cataract, retinal detachment can cause the eye to deviate.

 
☛ What are the symptoms of squint?

When the eyes are not aligned properly, each eye is focusing on different objects. Therefore, two different images reach the brain which causes confusion and may affect vision in two ways:
Children tend to focus only on the good quality image and ignore the image coming from the deviated eye. This suppression of the image from the deviating eye results in poor development of vision in the eye which result is “Lazy Eye” or “Amblyopia”

In adults, patients cannot ignore the images from either eye and therefore will have double vision. This is often very annoying and interferes with day – to – day work.

 
☛ What are the symptoms of squint?

Children may not express symptoms of double vision. If there is misalignment of eyes in any child more than one month old then the child should be evaluated by the ophthalmologist.

☛ How is squint diagnosed?

Squint is diagnosed with the help of special tests done by the ophthalmologist in addition to routine clinical examination.

 
☛ How is squint treated?

A detailed examination including checking the refractive error should be done. Squint can be managed with the help of

  • Corrective glasses
  • Exercises
  • Surgery
