Long-term strabismus complications following retinal detachment surgery.

Thirty-three consecutive patients with persistent strabismus following retinal detachment surgery were studied retrospectively. A large number of vertical and torsional problems were seen. Various restrictive abnormalities were identified during strabismus surgery. These included superior oblique tendon displacement anteriorly, leash and reverse leash types of restrictions, myoscleral adhesions posterior to the exoplants, and stretching of the muscles induced by large underlying exoplants. The results following strabismus surgery were analyzed. Eighty percent of the patients were able to achieve single binocular vision in the primary field of gaze, with a low incidence of complications. The adjustable suture procedure was thought to be helpful.
