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<21 mm Hg at the end of the follow-up period. RESULTS: The median preoperative pressure was 29 mm Hg [interquartile range (IQR)=5 mm Hg], with an average of 2.8 glaucoma medications (range, 1 to 4). At 6 months postoperatively the median IOP was 18 mm Hg (IQR=1.75 mm Hg) with no further significant increases recorded, settling at 19 mm Hg (IQR=3.25 mm Hg) at the end of the 24-month follow-up. Success was achieved in all 19 cases (100%), and only 1 patient (5%) required postoperative antiglaucoma therapy to reach the target pressure. At 24 months after surgery, 18 of 19 (95%) amniotic membrane filtering blebs were functioning well without antiglaucoma therapy. No patients had severe intraoperative or postoperative complications. CONCLUSIONS: Amniotic membrane transplantation in trabeculectomy seems to be a safe and useful procedure for improving the surgical outcome and maintaining low postoperative IOP in patients with a high risk of surgical failure.
