Abstract

Purpose: We report a new technique for treating leaking or painful filtering blebs and the results to date. Methods: A 9-0 or 10-0 nylon suture was passed for 1-2 mm at half-depth in the peripheral cornea, parallel to the bleb, the suture passed back over the bleb, a 2-4 mm bite of conjunctiva-Tenon's taken posterior to the bleb, the suture passed back over the bleb and the suture tied tightly. The trimmed knot was turned into the cornea. Sutures were removed after one to several weeks when the desired effect (epithelialization over leaks, thickening and reduction of profile for painful blebs). Results: Since May of 1992, 46 eyes of 44 patients were treated. Most had failed conventional therapies. The success rates were 69% for leaks and 80% for dysesthesia. The sutures were usually well tolerated, but occasionally erode blebs, and one case of endophthalmitis and one of late bleb failure occurred. Conclusions: Compression sutures over blebs were observed to markedly reduce Seidel positive leaks immediately after placement, suggesting that compression of Tenon's in a bleb reduces fluid conductivity (as H Quigley suggests happens in Tenon's cysts), allowing epithelial healing. In ischemic blebs, compression stitches induce thickening, a lowering of profile and induction of vessels. Our technique is an effective, inexpensive, but not risk-free treatment.
