BACKGROUND: To determine the success rate of trabeculotomy in patients with juvenile and late-juvenile glaucoma in a retrospective study. PATIENTS AND METHODS: Forty-six eyes of 41 juvenile glaucoma patients (24 female, 17 male) were submitted to trabeculotomy during the period 1980-1997. Patients' age at the time of surgery was 30.2 ± 10.5 years (11-49 years, median 21 years). Follow-up time was 35 ± 46 months (1-155 months). RESULTS: Median preoperative visual acuity was 1.0 (range, 0.002-1.25), postoperative visual acuity at the end of the follow-up period was 0.8 (median) with a range of from 0.002 to 1.2. In all patients, preoperative intraocular pressure (IOP) was elevated and a glaucomatous configuration of the optic disc was noted. Preoperative IOP was 30.5 ± 13.2 mmHg, postoperatively 16.2 ± 5 mmHg. Mean decrease of IOP postoperatively was 54.4%. In 37% of the eyes, IOP was lower than 23 mmHg without additional medication, in 47% IOP was lower than 23 mmHg with additional medication. In eight eyes additional antiglaucoma surgery was necessary. After a follow-up of 60 months, 81% of patients (n = 37 eyes) had an IOP below 23 mmHg, after 120 months in 80% of patients (n = 29 eyes), IOP was below 23 mmHg. CONCLUSIONS: The success rate of trabeculotomy (defined as the ability to lower IOP below 23 mmHg with or without antiglaucoma medication) in these patients was 84%. After a second operation, the success rate was 89%. Trabeculotomy for patients with juvenile open-angle glaucoma is a safe procedure and avoids the problems and complications of filtering procedures.
