Abstract

PURPOSE
To evaluate the efficacy and safety of 5-0 prolene ligation around the Ahmed glaucoma valve tube to prevent the postoperative hypotony and flat anterior chamber. METHODS: Medical records of twenty one eyes of 20 patients those had got Ahmed valve implant surgery with temporary ligation of the tube with 5-0 prolene were retrospectively evaluated for efficacy of the pressure control and complications before and after the remove of the ligation suture. RESULTS: Preoperative intraocular pressure(IOP) was 46.1+/-9.1 mmHg. The ligation suture was removed at 2.8+/-1.5 postoperative day. Postoperative IOP before the removal of the suture was 24.8+/-15.4 mmHg at the day of removal. After removal of the ligation suture, the IOP decreased to 15.6+/-5.9 mmHg and 12.2+/-4.2 mmHg at one day and 12 weeks after the removal respectively. Complications before the removal of the ligation suture were mild hyphema and corneal edema, developed in one eye each. After the removal, shallow anterior chamber and choroidal detachment was developed in one eye. CONCLUSIONS: Although the efficacy of the temporary ligation of the tube in Ahmed valve implant surgery in controlling the IOP was similar to that of conventional Ahmed valve implant surgery without ligation, the early postoperative complications associated with the overfiltration appeared to be less frequent than conventional Ahmed valve implant surgery.
