Diagnosing Squint or Strabismus

Squint is the misalignment of the eye where each eye points in a different direction. This misalignment may be constant or intermittent. The deviation of the eye can be in any direction inward, outward, upward, or downward. The disorder can be unilateral (squint is in the same eye) or alternating.

Squint is also called strabismus can be a congenital defect or can occur later in life. Early diagnosis of the condition is important. Children who are diagnosed with a squint may develop poor vision in one eye (lazy eyes). Adults with the condition often have double vision. 

Strabismus occurs when the extraocular muscles (muscles that control the movement of the eye and eyelid ) do not work together. Other causes of the disorder in the brain where the part of the brain that coordinates eyes muscles does not function properly. 

Strabismus is classified by the direction of the eye turn into:-

  • Esotropia or inward turning of the eye
  • Exotropia or outward turning of the eye
  • Hypertropia or the upward turning of the eye
  • Hypotropia or inward turning of the eye

The two most common squints in adults and children are accommodating esotropia and intermittent exotropia.
