Abstract

Thirteen patients with Duane's syndrome, Type I, underwent full vertical rectus muscle transposition. Prior to surgery, all patients had esotropia in the primary position and 11 patients had a face turn. Postoperatively, esotropia was improved in 77%. The face turn was improved in 100% and eliminated in 69%. Abduction ability was increased and binocular diplopia-free field size enlarged to a mean of 60 degrees. Seven patients (54%) with a mean preoperative deviation of 17 prism diopters required only vertical rectus muscle transposition to improve their face turn and strabismus. Six patients (46%) with a mean preoperative deviation of 30 delta required an additional medial rectus recession several months later. Two patients (15%) developed a vertical deviation following vertical rectus muscle transposition.
