Abstract
Purpose: To report outcomes and complications of trabeculotomy ab interno using the Trab360 device (Trab360; Sight Sciences, Menlo Park, California, USA) in eyes with childhood glaucomas. Design: Multicenter retrospective interventional case series. Methods: Eyes with childhood glaucomas that underwent Trab360 with at least 3 months follow-up were evaluated. Postoperative intraocular pressure (IOP) less than or equal to 24 mm Hg with or without medications and no additional surgery defined success. Results: Forty-six eyes of 41 patients were included. Median age at surgery was 12 months (range 1-325 months, mean 71 months); 54% prior to 20 months. A total of 48% were right eyes; 48% were male. Mean treatment was 290°. Median follow-up was 14.5 months (range 6-34 months, mean 16.2 months). Median preoperative IOP was 30 mm Hg (range 18-49 mm Hg, mean 30.9 mm Hg); median postoperative IOP was 18 mm Hg (range 5-40 mm Hg, mean 20.3 mm Hg]. Median number of preoperative glaucoma medications was 2.5 (range 0-5, mean 2.6); median number postoperatively was 1 (range 0-4, mean 1.6). Success was achieved in 67.4% (95% CI: 51.9%-80.0%) of eyes. Among 40 eyes for which Trab360 was the first glaucoma surgery, success rate was 70% (95% CI 53.3%-82.9%). Success was achieved in 81% (95% CI 57.4%-93.7%) of primary congenital glaucoma (PCG) eyes. Among 18 PCG eyes for which Trab360 was the first glaucoma surgery, success rate was 83.3% (95% CI 57.7%-95.6%). Two eyes (4.3%) suffered cyclodialysis. There were no other significant complications. Conclusions: Trab360 success resembles literature on other angle surgeries for childhood glaucomas. Good surgical technique and caution in high-risk angles is imperative to avoid cyclodialysis. Our study is limited by the imperfections inherent in any retrospective analysis. Single-incision ab interno trabeculotomy with the Trab360 device is effective and safe for treating childhood glaucomas, especially PCG.
