Methods: Four eyes of 4 patients presenting post-trabeculectomy with mitomycin-A complications (leaking blebs, 3 eyes, and inadvertent filtering bleb, 1 eye) underwent bleb reconstruction with amniotic membrane. Results: Mean follow-up time was 5.75 months (range, 2 to 9 months). Complete resolution was achieved in all cases. In one case it was necessary to add cyanoacrylate tissue adhesive and place a therapeutic contact lens. The epithelialization occurred within 14.75 days (range, 8 to 21 days). Visual acuity improved in 1 patient and did not change in the other 3 cases. Intraocular pressure remained under control in all patients with the additional use of topical antiglaucomatous medication. Conclusions: The use of amniotic membrane seems to represent a viable option for the treatment of post-trabeculectomy leaking and inadvertent filtering blebs that were resistant to conventional therapy. More cases are necessary for further analysis and to refine the technique.
