Strabismus is derived from a Greek word, which means “eyes looking obliquely.” Strabismus means misaligned eyes. Often strabismic eyes are referred to as “squinting eyes,” “crossed eyes,” and “wall eyes.” Usually, both eyes fixate equally while focusing on an object with the head held in the primary position. In strabismus or squint, one or both eyes deviate inwards or outwards and appear to be in non-alignment towards the direction of the focused object. It can be due to refractive error or binocular fusion abnormalities or neuromuscular anomalies of ocular movements. If diagnosed and treated early, strabismus has a very good prognosis. Treatment is usually by refractive error correction, orthoptic exercises, occlusive patching, topical medications, and extraocular muscle surgery.
