Success Rate of Augmented Trabeculectomy in Primary Congenital Glaucoma.

Abstract

To evaluate the outcome of trabeculectomy augmented with mitomycin C in primary congenital glaucoma and to document the complications of the procedure in young children. This was a prospective study of children younger than 2 years with primary congenital glaucoma who were treated with primary trabeculectomy with mitomycin C. After surgery, patients were observed for a minimum of 1 year. Trabeculectomy success was defined as an intraocular pressure (IOP) of 21 mm Hg or less without (absolute success) or with (qualified success) topical antiglaucoma medications. Surgical success was assessed at 1, 6, and 12 months after the procedure. Seventy-four eyes of 42 children were included in the current study. The mean age was 11.7 ± 8.5 months. Of the 42 children, 57.2% were male and 42.8% were female. The mean IOP after surgery was significantly lower than the preoperative IOP (P < .0001). Absolute success was observed in 98.6%, 50%, and 27% of eyes at 1, 6, and 12 months, respectively. Qualified success was achieved in 1.4%, 36.5%, and 48.6% of eyes at 1, 6, and 12 months, respectively. Overall success of the procedure was 100% at 1 month but reduced to 86.5% at 6 months and 75.7% at 12 months. In 24.3% of eyes, IOP was not controlled even with adjunctive topical glaucoma medications and was considered a failure. Postoperative complications were shallow anterior chamber (10.8%), collapsed anterior chamber (1.3%), and choroidal detachment (12.0%). Complications were managed conservatively, and 6 eyes needed surgical intervention. Augmented trabeculectomy is a useful primary procedure in children with primary congenital glaucoma. Topical glaucoma medications supplement the success of the procedure. [J Pediatr Ophthalmol Strabismus. 2022;59(3):180-186.].
