Strabismus-Squint indore

What is Strabismus/Squint?

Strabismus, also known as crossed or turned eye, is the medical term used when the two eyes are not straight. It occurs in appr- oximately 2 to 4 percent of the population.

What Are the Different Types of Squint ?


A child may be born with this condition, or it may develop within a few months of birth or around two years of age. This is also called esotropia, or convergent squint.


A child may be born with this condition, or it may develop later. This is also called exotropia, or divergent squint.

3. Vertical Squint

The eyes are out of alignment vertically.


  • Turned or crossed eye.
  • Squinting.
  • Head tilting or turning.
  • Double vision (in some cases).


The aim of treatment is to restore good vision to each eye and good binocular vision. Treatment usually includes patching the eye that is always straight to bring the vision up to normal in the turned eye. Glasses may be used, particularly for eyes that are out of focus. Glasses and special drops (phospholine iodide) may also help straighten the eyes. Surgery on the eye muscles is sometimes necessary.

Why is an operation necessary?

Sometimes it is the only way of straightening the eye sufficiently for sight to be restored in the squinting eye. If performed at the appropriate time, results can be very good and satisfactory and Three Dimensional vision can be developed. However, when the results are only cosmetic, they improve the child's appearance only. It is sometimes possible to do more than one operation to achieve the desired results.

How is the operation done?

It involves repositioning the relevant eye muscles on the eye ball. This could mean either shortening or loosening of muscles with surgery.

What happens after operation?

Squint surgery is a day care procedure where the patient is sent home on the day of surgery itself. The eye may appear red after surgery, but this settles down in a few weeks. One should be able to return to school after about 10 days of surgery. If the child wears the spectacles before the operation, spectacle will still be needed after the surgery.
