BACKGROUND AND OBJECTIVE: To evaluate the effect of intraoperative intracameral injection of 2% hydroxypropyl methylcellulose (HPMC) on anterior chamber depth and intraocular pressure (IOP) following trabeculectomy in eyes with uncontrolled primary open-angle glaucoma in a prospective randomized manner.
PATIENTS AND METHODS: Thirty consecutive eyes with primary open-angle glaucoma scheduled for trabeculectomy were randomized to conventional trabeculectomy without HPMC injection (group I; n = 15) or to intracameral injection of 2% HPMC during trabeculectomy (group II; n = 15). All patients were observed serially on days 1, 3, 5, 7, and 14 and months 1, 3, and 6 postoperatively. The main outcome measure was restoration of anterior chamber depth to preoperative level with IOP of less than 21 mm Hg with no additional antiglaucoma medication or surgery.
RESULTS: The anterior chamber depth decreased from 2.5 +/- 0.53 to 1.5 +/- 0.94 mm on postoperative day 1 in group I and increased slightly from 2.4 +/- 0.43 to 2.5 +/- 0.36 mm on postoperative day 1 in group II (P = .04). Overall, the IOP decreased to 5.0 +/- 2.8 mm Hg in group I (87% reduction) and 9.0 +/- 4.6 mm Hg in group II (70% reduction). Two eyes developed postoperative flat anterior chamber and related complications in group I, whereas none of the eyes in group II developed such complications.
CONCLUSIONS: Intracameral injection of 2% HPMC during trabeculectomy helps to maintain anterior chamber depth and reduces incidence of complications related to shallow anterior chamber depth following trabeculectomy.
