Cyclic esotropia in a patient with unilateral traumatic aphakia: case report.

Cyclic esotropia is a rare and poorly understood condition normally treated by correcting the deviation measured on the squinting day. Control in some patients with this condition can be gained by correcting their refractive errors, thereby improving acuity. We report on an adult patient who developed cyclic esotropia after unilateral traumatic aphakia with failed contact lens wear whose squint was corrected by secondary intraocular lens implantation. This may be explained by the reduction in the degree of aneisokonia which subsequently improved steropsis.
