ABSTRACT

Antiglaucomatous filtering bleb fibrosis may occur soon or later postoperatively, because of scarring of the conjunctiva and Tenon’s capsule. Studies show that it is especially prevalent in black people, in whom fibrosis can occur in up to 80% of trabeculectomy cases1-3. Since the 1980s several nonpenetrating surgical techniques have been introduced to resolve the problem4-8. The aim is to reduce intraoperative and postoperative complications, such as hypotony, shallow anterior chamber, inflammative reaction and bleb fibrosis. Recently, such surgical techniques have become quite popular, particularly when combined with phacoemulsification9-11,14,15.
