Ocular Complications in Strabismus fîxus convergens

Abstract

Two cases of strabismus fixus are described. Histopathological examination of the eyeballs from both patients revealed the following complications of this rare disorder: ocular ischemia, atrophy of the optic nerve, and old central retinal artery occlusion. These complications are likely to be secondary to the mechanical stretching and torsion of the optic nerve with subsequent strangulation of its blood supply. Early surgical correction of strabismus fixus is recommended.
