Trabeculectomy Versus EX-PRESS Shunt Versus Ahmed Valve Implant: Short-term Effects on Corneal Endothelial Cells

Abstract

We read the recent article by Casini and associates, entitled “Trabeculectomy versus EX-PRESS shunt versus Ahmed valve implant: Short-term effects on corneal endothelial cells,” with great interest. 1 Casini G.

They found that the EX-PRESS shunt procedure compared to trabeculectomy and Ahmed glaucoma valve procedure showed no short-term effects (in 3 months) on corneal endothelial cells in patients with primary open-angle glaucoma.

During 12.2 months mean follow-up, none of the patients in the study experienced worsening of the graft. Full-Text PDF
