Primary Infantile Exotropia with Lambda Pattern- A Case Report

Infantile exotropia is a relatively rare strabismus disorder characterized by outward deviation of one or both eyes. Because of its rarity, there are few population-based studies to identify its true incidence. Here is a 12years old child presented with abnormal outward eye deviation since birth. Ocular examination revealed infantile exotropia with lambda pattern which is among the rarest case ever found of which squint surgery was done and the alignment was brought back to normal. Definitive treatment is surgery before age of two years to have best binocular single vision outcome, wherein this patient lost his binocular single vision due to the delay.
