Abstract

Purpose: To assess the efficacy of viscotrabeculotomy in the surgical management of congenital glaucoma as compared to conventional trabeculotomy.Methods: In a prospective study patients with congenital glaucoma matching the inclusion criteria underwent viscotrabeculotomy (VT) group, 21 eyes, and trabeculotomy (T) group, 20 eyes. Patients were followed up for minimum of 6 months. A probability value (p value) less than 0.05 was considered significant.Results: The mean preoperative IOP was 23.5 and 24.3 mmHg in the VT and T groups respectively. Postoperatively, IOP dropped at six months to 14.7 and 17 mmHg in the VT and T groups respectively. That was significant in either group when compared to preoperative IOP (p=0.01 & p=0.001 in the VT & T groups respectively), but was not significant between both groups at the same point of comparison (p=0.853). At 6 months postoperatively, complete success was achieved in 61.9% in the VT group compared to 60.0% in the T group. This slight preference for VT (Odds ratio 1.08) was statistically not significant in comparison to that achieved in the T group (p=0.448). The incidence of operative hyphema was 38.1% in the VT group compared to 20% in the T group. Although the relative risk for hyphema in the VT/T was 1.9 (confidence interval 0.6785 to 5.3475), that was statistically insignificant (p=0.22). Conclusions: Both techniques were equally effective in the reduction of IOP in the management of congenital glaucoma. Viscotrabeculotomy does not appear to improve the surgical outcome in congenital glaucoma.
