The "Deroofing" of Schlemm's Canal in Patients With Open-Angle Glaucoma Through Placement of a Collagen Drainage Device

Abstract

The nonpenetrating technique for deroofing the canal effectively allows the drainage of aqueous to acceptable levels (in the range of 15 to 17 mm Hg) without the complications associated with penetrating trabeculectomy. Complications are rare, and the collagen drainage device appears to be effective for allowing the drainage site to remain patent after its dissolution.
