PURPOSE To quantify the long-term outcomes of congenital glaucoma and surgical success rates following pseudo 360-degree trabeculotomy surgery at Children's Medical Center in Dallas. PATIENTS AND METHODS An International Classification of Diseases (ICD-9) database was utilized for a retrospective chart review. Thirty-eight eyes of 24 who underwent primary trabeculotomy with a pseudo 360-degree technique between June 1, 1992 and December 31, 2005 were studied. RESULTS Mean age at the time of trabeculotomy was 11.1 ± 3.0 months, with seven eyes operated on after 1 year of age. Mean follow-up was 85.1 ± 9.0 months. Mean intraocular pressure (IOP) at the time of glaucoma diagnosis was 32.7 ± 1.1 mmHg, and final mean IOP for all eyes (after trabeculotomy and any additional surgery and/or glaucoma medications) was 17.9 ± 0.8 mmHg. With trabeculotomy and medication alone, mean final IOP was 19.9 ± 1.1 mmHg, with a mean drop in IOP of 12.5 ± 1.4 mmHg. Surgical success, defined by adequate IOP control, was achieved in 30 eyes (78.96%) at most recent follow-up. Kaplan-Meier analysis demonstrated 5- and 10-year survival probabilities of 93.1% and 66.8%, respectively. Seventeen eyes (44.7% of all eyes) achieved complete success, meaning IOP control
