Postoperative outcome of three different procedures for childhood glaucoma

Abstract

PurposeTo investigate the long-term postoperative outcome of three surgical procedures for childhood glaucoma.Patients and methodsIn this retrospective study, the patients were divided into a goniotomy group, a trabeculotomy group, and a filtering surgery group, based on the initial surgical procedure. Failure was defined as an IOP ≥21 mmHg with medication at two consecutive visits. A Kaplan–Meier analysis was applied to calculate the probability of success. Additional metrics included IOP, number of additional operations, eye drop scores, and visual acuity.ResultsWe studied 40 eyes of 25 patients, 21 eyes of 15 patients, and 12 eyes of 7 patients in the goniotomy, trabeculotomy, and filtering surgery groups, respectively. The 10- and 20-year probability of success was 65.2% and 65.2%, 42.2% and NA (no data for 20 years), and 91.7% and 80.2% for the goniotomy, trabeculotomy, and filtering surgery groups, respectively.ConclusionAll three procedures maintained an IOP of less than 21 mmHg for up to 10 years in 65.2%, 42.2%, and 91.7% of childhood glaucoma cases.

Success Rate of Goniotomy in Terms of Intraocular Pressure Control in Pediatric Glaucoma Patients

“…In a study conducted by Huang et al, the success rate of 65.2% for goniotomy after ten years was noted. 18 This difference in success rate may be explained by a more extended follow-up period, up to 10 years. A study conducted in Northern Tanzania showed a success rate of 38% at 12 months follow up.…”
