Abstract
Objective: To describe the use of amniotic membrane (AM) in reoperations to decrease scar formation and to improve ductions. Design: Prospective interventional case series. Participants: Four previously operated cases with restrictive strabismus. Methods: Objective clinical findings were recorded during both pre and post-operative periods. Excision of adhesions and scar tissue, repositioning of extraocular muscles and placement of AM between muscle, sclera and tenon tissue were performed. Results: Orthophoria with no duction deficits was achieved in 2 patients. One patient with fat adherence syndrome had orthophoria with -1 adduction deficit. Only one patient with congenital fibrosis syndrome had 25 PD of esotropia with abduction deficit (-2). Conclusions: We believe that AM placement between the extra ocular muscle, sclera and tenon tissue improves the ductions by inhibiting post-operative scar formation.
