Glaucoma drainage implant surgery.

Abstract

Glaucoma drainage implant (GDI) surgery represents a significant advance in the treatment of refractory glaucomas. Recent randomized clinical trials have compared the efficacy and safety of this technique to standard trabeculectomy. Several types of implants are currently available and differ in surface area, shape, composition, and presence or absence of a flow-restricting valve. A prospective, randomized clinical trial comparing two types of GDIs is ongoing. GDIs may be placed in the anterior chamber, ciliary sulcus, or pars plana. Several types of patch graft material may be utilized to prevent tube erosion. Potential complications of GDI surgery may relate to immediate or late-onset hypotony, motility disturbances, corneal decompensation, or tube erosion.
