Use of Gore-Tex in Bleb Revision after Trabeculectomy with Mitomycin

ABSTRACT

Trabeculectomy, as a surgical intervention in the treatment of glaucoma, has become most popular. The most common cause of filtration failure is obstruction of aqueous outflow due to bleb fibrosis. Adjunctive intraoperative mitomycin-C has been reported to improve the success of filtration surgery in eyes of high risk for failure. But its use increases the rate of complications after filtering surgery: especially postoperative hypotony, wound leakage, and scleral necrosis. We have experienced two patients whose scleral flaps were necrotized after trabeculectomy with mitomycin-C in uncomplicated glaucoma. We report successful results in revision of filtering bleb by using Gore-Tex as a patch graft.
