Viscocanalostomy

Abstract

Viscocanalostomy is a non-perforating filtration surgery used for patients with uncontrolled glaucoma, as an alternative to trabeculectomy. Bypassing the creation of a full thickness sclerostomy (as is created in traditional trabeculectomy) avoids the complications of blebitis, bleb-related endophthalmitis, as well as complications from exposure to use of anti-metabolites (i.e. Mitomycin C and 5-FU). Viscocanalostomy is performed to relieve outflow obstruction by dilating Schlemm's canal and b y exicing the inner wall of Schlemm's canal/juxtacanalicular tissue to create a trabecular-Descemet opening.
