What is Squint?

Squint ,in layman language means the deviating eye, is a visual defect in which eyes are not in alignment and point in different directions. One eye may look straight ahead, while the other eye may turn inward, outward, upward or downward.


The exact cause of strabismus is not fully understood. Six eye muscles, controlling the eye movement, are attached to the outside of each eye. In each eye, two muscles function to move the eye right or left. The other four muscles move it up or down or at an angle.

Strabismus is especially common among children with disorders that affect the brain such as:

  • Cerebral palsy
  • Down syndrome
  • Hydrocephalus, and
  • Brain tumors.


  • eyes are deviated
  • Vision in the deviated eye is generally weak

When to consult a doctor?

  • When you observe the deviation is increasing day by day, it should be reported.
  • After some diseases like typhoid, also sometimes the deviation develops.
  • If the squint develops after a an accident or without the patient’s realisation the eyes have deviated suddenly, he should immediately report to an ophthalmologist.

Most common types

  • Esotropia- inward movement of the eyes
  • Exotropia-outward movement of the eyes


  • Prism therapy
  • Surgeries
  • Exercises
