Abstract

Abstract:

Objective To investigate the effect of internal trabeculectomy on postoperative intraocular pressure and visual acuity in patients with primary open angle glaucoma (POAG).Methods A total of 126 POAG patients underwent internal trabeculectomy were included in this study. Intraocular pressure, types of drug used, visual acuity and complications were compared before and after operation.Results Intraocular pressure was significantly decreased, types of drug used were significantly reduced and visual acuity was significantly improved at 1 week, 1 month and 3 months after surgery (P < 0.05). The incidence of postoperative intraocular pressure rebound complication was the highest in postoperative patients (27.78%), followed by hyphema (14.29%), corneal edema (10.32%) and ciliary detachment (7.14%).Conclusion Internal trabeculectomy for POAG patients can effectively control the decrease of intraocular pressure in patients, help to restore vision, reduce types of drug used, and the effect is ideal, and the clinical application value is high.

Key words: glaucoma, open-angle, intraocular tension, vision, postoperative complications, internal trabeculectomy
