Comparative Study of Combined Cataract Surgery in Primary Angle-Closure Glaucoma

ABSTRACT

Trabeculectomy, as an operation precedure for glaucoman, decrease intraocular pressure(IOP)effectively. But the amount of decrease in IOP is different according to the etiology of glaucoma. Thirty four primary angle-closure glaucoma patients (37 eyes)who had undergone trabeculectomy only or trabeculecomy combined with cataract surgery and had been subsequently followed up for least 6 months, were enrolled in this study. In 12 patients(14 eyes) among 16 patients (18 eyes, Group 1) who had undergone trabeculecto-my only, IOP was controlled without glaucoma medication, while glaucoma medication was needed in the other 4 patients (4 eyes). Among 18 patients (19 eyes, Group 2) who had undergone trabeculectomy combined with cataract surgery, IOP were controlled without glaucoma medication 9 patients (10 eyes); controlled with medication in 8 patients (8 eyes); and not controlled even with 1 patient (1 eye). The amount of decrease in IOP was no statistically different between the two groups. Group 2 had deeper anterior chamber than Group 1 (p<0.01). The above results suggest that the combined pro-cedure may benefit in primary angle-closure glaucoma patients, especially old complicated patients.
