Abstract

Glaucoma drainage devices are helpful in the management of intractable glaucoma, which does not respond well to conventional medical and surgical therapies. Surgeons also may choose to use glaucoma drainage devices for primary surgery for glaucoma. The Ahmed Glaucoma Valve is a glaucoma drainage device that has a flow-resistive valve mechanism. This valve is helpful in minimizing postoperative hypotony and complications associated with hypotony, including flat anterior chamber, choroidal effusions, and suprachoroidal hemorrhage.
