Outcomes of Trabeculectomy Versus Trabeculectomy Combined with Deep Sclerectomy in Glaucoma Patients: 15-Month Follow-Up (A Preliminary Report)

Abstract

Purpose: To compare surgical efficiencies of tracbeculectomy versus trabeculectomy combined with deep sclerectomy in glaucoma patients. Methods: From July 1995 to July 2001, 49 eyes of 37 primary glaucoma patients (age＞40 years old) were enrolled in this study. Twenty-eight eyes received trabeculectomy (group T), and 21 eyes received trabeculectomy combined with deep sclerectomy (group TS). The transcorneal releasable suture method was performed on all 49 eyes. No intraoperative mitomycin-C (MMC) application was used for patients in this study. Complete surgical success was defined as a postoperative intraocular pressure (IOP) lower than 21 mm Hg, without any antiglaucoma medication. Any postoperative lop complication as well as the success rate was recorded and compared. Results: The follow-up period for all patients was 15 months. In group T, the final mean IOP was 15.6±3.76 mm Hg. Four eyes failed to achieve surgical success. In group TS, the final mean IOP was 13.8±3.87 mm Hg. Surgical success rate was 100%. In spite of no significant difference between the success rates of these two surgical methods, it appeared that IOP was better controlled in the group TS. Conclusions: Both techniques, trabeculectomy and trabeculectomy combined with deep sclerectomy, controlled IOP efficaciously at our endpoint, in primary glaucoma patients.
