Objective: To evaluate patients monitored for glaucoma and operated with trabeculectomy combined with deep sclerectomy under an anterior chamber maintainer.
Methods: In this retrospective study, fifteen eyes of 15 patients diagnosed with primary open angle glaucoma (POAG) who show up regularly for follow-up examinations between April 2006 and May 2010 were included in this study. Pre-operative/post-operative intraocular pressure (IOP) and the number of antiglaucomatous medications were evaluated.
Results: The mean age was 64.6 ± 11.4 (33-80) years and the mean follow-up period was 22.4 ± 16.2 months (6-55). The mean pre-operative IOP was 24.6 ± 8.0 (12-40 mmHg), and the mean cup/disc (c/d) ratio was 0.71 ± 0. 25. According to the Hodapp classification, the mean damage in the visual field was 2.1 ± 0.9. Mean post-operative IOP at months 1, 12, and 24 was 13.2 ± 3.4, 13.6 ± 4.6 and 13.8 ± 2.8 mmHg, respectively. The average number of pre-operative antiglaucomatous medications was 3.1 whereas the average numbers of post-operative antiglaucomatous medications were 1.8, 0.6 and 0.8 respectively.
Conclusion: Modified trabeculectomy has low rates of complication and results in a significant decrease in postoperative IOP, as well as the number of antiglaucomatous medications used.
