Ophthalmology · Squint: infantile esotropia

Sample item

A 6-month-old infant has a large angle constant esotropia with cross-fixation. What is the usual management?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Early surgery to align the eyes, usually before 2 years

Infantile esotropia is a large constant deviation not related to refractive error, and surgery is done early to give a chance for binocularity. Amblyopia, if present, is treated first.

Option by option

  • A. Convex glasses alone

    Glasses correct accommodative, not infantile, esotropia.

  • B. Botulinum toxin to the lateral rectus only

    Botulinum toxin to the lateral rectus would worsen an esotropia.

  • C. Observation until 10 years

    Delay lessens binocular outcome.

  • D. Early surgery to align the eyes, usually before 2 years (correct)

    Correct. Early alignment is the goal.
