Abstract
PURPOSE: This study compares the long-term efficacy of circumferential trabeculotomy to that of conventional angle surgeries in primary congenital glaucoma (PCG), as judged by glaucoma and visual outcomes. DESIGN: Retrospective observational case series. METHODS: Setting: Emory Eye Center, Atlanta, Georgia. STUDY POPULATION: This was a single-institution retrospective study involving children with PCG who underwent circumferential trabeculotomy, standard trabeculotomy, or goniotomy with ≥2-year follow-up. MAIN OUTCOME MEASURES: Postoperative success (intraocular pressure [IOP] < 22 mm Hg ± glaucoma medications, without glaucoma progression/additional IOP-lowering surgery), Snellen-equivalent visual acuity (VA), and IOP at last follow-up. Kaplan-Meier method estimated the probability of glaucoma control vs time postoperatively, and values were compared between angle surgery cohorts using Wilcoxon signed rank tests, Mann-Whitney U tests, and Fisher exact tests. RESULTS: Included were 58 eyes (33 children) after circumferential trabeculotomy and 42 eyes (27 children) after standard trabeculotomy/goniotomy, with mean follow-up of 7.2 ± 4.0 and 8.2 ± 4.5 years, respectively. Postoperative success at last follow-up in the circumferential vs conventional cohorts was 81% (47 of 58 eyes) vs 31% (13 of 42 eyes) (P < .0001). At last follow-up, the circumferential cohort had better median VA than the conventional cohort (20/30 (interquartile range [IQR] 20/25 to 20/70) vs 20/70 (IQR 20/40 to 20/200), P = .009), required fewer glaucoma medications (0.55 ± 1.2 vs 1.61 ± 1.51, P < .0001), had lower IOP in first operated eye (15.2 ± 3.6 vs 18.2 ± 7.0, P = .048), and had comparable incidence of devastating complications (P = .065). CONCLUSIONS: In this retrospective study, circumferential trabeculotomy afforded better long-term success and visual outcomes than conventional angle surgery for children with PCG.
