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.
