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

Outcome of goniotomy in pediatric glaucoma

Abstract

Objective: To determine the success rate of goniotomy in terms of reduction in intraocular pressure.

Study Design: Quasi-experimental study.

Place and Duration of Study: Department of Ophthalmology, at Faisalabad Medical University/Allied Hospital Faisalabad from Apr 2016 to Aug 2017.

Methodology: A total of 65 patients were enrolled in our study. The patients with intraocular pressure greater than 21 mm Hg and corneal diameter less than 13 millimetres were included. Intraocular pressure was measured before and four-weeks after goniotomy. Intraocular pressure measurement of less than 21 mm Hg four- weeks after surgery was considered successful.

Results: Out of 65 patients, 35 (53.8 %) were male, and 30 (46.2%) were female. The age of patients ranged from 3 months to 33 months, with a mean age of 15.25 ± 7.66 months. Among 65 patients operated for goniotomy, the procedure was found successful in 55 (84.6%) patients, and only 10 (15.4%) patients did not show improvement following goniotomy. The fall in intraocular pressure from baseline to post-operative values of intraocular pressure was statistically significant (p-value < 0.01).

Conclusions: Goniotomy is an effective procedure for lowering intraocular pressure in childhood glaucoma patients and can be offered as a primary and initial procedure at an early age.
