Abstract

There are several causes developing diplopia after cataract surgery. Among these causes, central fusion disruption may be developed in longstanding unilateral traumatic cataract and uncorrected aphakia. The pathophysiology is unknown, but time interval between sensory deprivation and optical correction is an important factor. The characteristic signs and symptoms are exotropic, hypotropic or excyclotropic deviation, and intractable diplopia with vertical bobbing movement of non-fixing eye, particularly near the angle of superimposition with prism or haploscopic device. The authors report two cases of central fusion disruption in longstanding unilateral traumatic cataract and uncorrected aphakia.
