This study aimed to determine success of trabeculectomy augmented with mitomycin C (MMC) in children with primary congenital glaucoma (PCG) and document complications of this intervention. Over a two-year period, the authors treated 74 eyes of 42 children with PCG, aged 11.7 ±8.5 months of which 76% were under 12 months of age. There were 24 males and 18 females. Seventy-six percent had bilateral glaucoma and mean follow-up was 18.2 ±3.8 months. Results at one year were presented. Preoperative intraocular pressure (IOP) was 27.3 ±4.2mmHg reducing to postop 17.9 ±6.3mmHg. Absolute success was defined as IOP without medication <21mmHg and was achieved in 73 children (98.6%) at one month and 20 (27%) at one year. Qualified success was defined as IOP with medication <21mmHg and achieved in one child (1.4%) at one month and 36 (48.6%) at one year. Total success at one year was 75.7%. Complications occurred in 18 eyes including shallow anterior chamber, collapsed anterior chamber and choroidal detachment. Mean time of failure with uncontrolled IOP was 7.6 ±3.8 months and requiring further surgery. Short follow-up was a limitation for this study. The authors conclude augmented trabeculectomy is a useful primary procedure with good success rate, and can be supplemented where needed by topical medication.
