PURPOSE: To report the outcomes of trabeculectomy in eyes with refractory acute primary angle-closure attack. METHODS: Patients with acute primary angle-closure attack and who underwent trabeculectomy for medically uncontrolled intraocular pressure within 2 months of presentation were retrospectively analyzed. Primary outcome was intraocular pressure (IOP). Secondary outcome measures were visual acuity, number of antiglaucoma medication (AGM), complications, and risk factors for failure of trabeculectomy. RESULTS: Thirty-five eyes of 31 patients with median (interquartile range) follow-up of 3 (0.5, 9) years were included in the study. Median age at presentation was 55 (47, 60) years. Median duration of symptoms at presentation was 10 (4, 16) days and median time from presentation to surgery was 13 (6, 25) days. Median IOP reduced from 42 (36, 46) to 13 (12, 16) mmHg (P < 0.001) and median number of AGM reduced from 3 (1, 3) to 0 (0, 0) after trabeculectomy at the end of 1 year. The probability of complete and qualified success was 88% (95% confidence interval [CI]: 72%-95%) and was 97% (95% CI: 81%-99%) at 1 year, respectively. Failure was noted in six eyes. Subsequent cataract surgery was needed in 13 eyes (37%) with a median duration from trabeculectomy being 6.75 (1, 11) years. None of the preoperative, intraoperative, or postoperative factors tested were associated with failure (P > 0.10 for all associations on Cox proportional hazard regression analysis). CONCLUSION: In medically unresponsive cases of acute primary angle-closure attack, primary trabeculectomy seems safe and effective in Indian eyes.
