Role of Ex-Press Glaucoma Shunt Implant in Glaucoma Filtering Surgery.

Glaucoma filtration surgery is a challenge for any glaucoma surgeon, because of its variable results and numerous complications. The Ex-PRESS glaucoma shunt, when used along with trabeculectomy gives a controlled drainage of aqueous and hence most of the complications due to over filtration like hypotony, choroidal detachment could be avoided. Tissue erosion and migration of device were initially noted, but later became rare due to modifications in techniques, like use under a sclera flap. The Ex-PRESS glaucoma shunt implant is a promising device in glaucoma filtration surgery, if used judiciously.
