Dehiscence of lateral rectus muscle following intrascleral buckling procedure.

Abstract

A 58-year-old woman underwent two operations within a week for repair of a rhegmatogenous retinal detachment in her left eye. The procedure consisted of the placement of an intrascleral buckle between the lateral and inferior rectus muscles and extending as explants under these two muscles. The ocular muscles were not disinserted as part of the surgery. Three and a half months postoperatively the patient had diplopia, marked left esotropia, and exposure of the buckle temporally. When the silicone implant was removed, the lateral rectus muscle was found to have spontaneously disinserted and to have reattached to the globe 9 mm posterior to its normal insertion.
