Purpose: To compare the surgical outcomes of triple procedure in patients with open-angle glaucoma and angle-closure glaucoma.
Methods: The patients who underwent triple procedures for open-angle glaucoma and angle-closure glaucoma and were followed up for more than 1 year postoperatively were retrospectively reviewed. Preoperative and postoperative visual acuity, intraocular pressure (IOP), visual field mean deviation, refractive error, number of medications, and complications were analyzed. The effect of surgery on IOP reduction and refractive error correction was compared.
Results: The IOP at 1 year postoperatively was 13.39 ± 2.25 mm Hg, 13.41 ± 2.79 mm Hg (p = 0.981) and IOP reduction was 4.51 ± 6.35 mm Hg, 9.11 ± 8.27 mm Hg (p = 0.042) in the open angle glaucoma group and angle closure glaucoma group, respectively. No patient in either group required reoperation due to uncontrolled IOP. The percentage of patients showing postoperative IOP reduction of at least 10% and 20% from baseline IOP was statistically higher in the angle-closure glaucoma group than in the open-angle glaucoma group. Prediction errors were -0.84 ± 0.88 D and -0.13 ± 0.65 D in the open-angle glaucoma group and angle-closure glaucoma group, respectively.
Conclusions: Triple procedure was effective in reducing IOP in both open-angle glaucoma and angle-closure glaucoma patients. The patients with angle-closure glaucoma showed better results in IOP control and refractive error correction compared with patients with angle-closure glaucoma.
