Amniotic Membrane Transplantation in Failed Trabeculectomy

PURPOSE:To determine the efficacy and safety of amniotic membrane transplantation for trabeculectomy in patients with previous failed filtering blebs. METHODS:A consecutive series of 19 eyes from 18 patients with 1 or more failed trabeculectomies were enrolled in this retrospective study. Trabeculectomy, with amniotic membrane positioned as a “graft” under the scleral flap, was performed, and the intraocular pressure (IOP), number of antiglaucoma medications, appearance of the filtering bleb, and intraoperative and postoperative complication data were retrospectively analyzed for a period of 24 months. Success was defined as IOP
