Abstract

Eight consecutive case of the slipped muscle are recognized and treated with the surgical intervention. All patients showed a large-angle exotropia(30 - 70 prism diopter), moderative to severe degree of limitation of adduction(-1.5 - -3) and negative forced duction test. Intraoperatively, we could identify the empty muscle capsule attached to the sclera with the tendon slipped posteriorly within its capsule. Repair is accomplished by resecting the empty capsule and advancing the true tendon to or toward the original insertion. After the average follow up period of 36.1 weeks, the amount of reduced within 10 prism diopters and limitation of duction within-0.5 in all patients. A better understanding of the pathology may lead to early diagnosis and surgical repair, and then the prognosis for functional and cosmetic result will be excellent.
