Persistent diplopia associated with strabismus surgery.

The primary therapeutic goal for patients with binocular vision problems is comfortable, single, clear, normal binocular vision at all distances and directions of gaze. Strabismus surgery is frequently used to assist in achieving this therapeutic goal. Strabismus surgery is also used for those patients who cannot achieve single normal binocular vision but who have a cosmetically noticeable ocular deviation. However, one of the complications of cosmetic strabismus surgery is persistent diplopia. This possibility must be considered seriously before any cosmetic strabismus surgery is performed. The purpose of this paper is to present a case report of a patient who had diplopia after cosmetic strabismus surgery to emphasize the need for careful consideration of the possibility of persistent diplopia after cosmetic strabismus surgery and how to avoid it.
