Prevention of early postoperative hypotony by partial ligation of silicone tube in Ahmed glaucoma valve implantation
Kee CJournal of Glaucoma 2001; 10: 466-469
PURPOSE: To determine the effectiveness of the partial ligation of a silicone tube of Ahmed glaucoma valve implantation to prevent early postoperative hypotony. PATIENTS AND METHODS: Thirty-two Korean patients were divided into two groups. Ahmed glaucoma valve implantation was performed with or without partial ligation in 16 eyes. The incidence of complications and the success rate in each group were compared. RESULTS: In the partial-ligation group, ten patients (62.5%) had successful intraocular pressure control (> 5 to < 22 mmHg) without any additional antiglaucoma medications, whereas intraocular pressure (IOP) in 12 patients (75.0%) was controlled with or without additional antiglaucoma medications. In the nonligation group, nine patients (56.3%) had successful IOP control without any additional medication, whereas IOP in 12 patients (75.0%) was controlled with or without additional antiglaucoma medication. Early postoperative hypotony occurred in one of 16 (6.3%) patients with partial ligation and in four of 16 (25%) patients without ligation. CONCLUSIONS: The partial ligation of a tube in Ahmed glaucoma valve implantation suggested a lower rate of hypotony and surgical complications. There was no significant difference in final success rate between the partial ligation and nonligation groups.
