Modified aqueous drainage implants in the treatment of complicated glaucomas in eyes with pre-existing episcleral bands

Objective: Control of intraocular pressure (IOP) after retinal surgery with scleral band placement may be problematic, In this study, outcome after si lastic drainage implant placement is reviewed. Design/Participants: A retrospective chart review of 11 eyes in 11 patients with severe glaucoma after multiple surgeries, including scleral buckle pr ocedures. Intervention: Patients received silastic drainage implant surgery, either a long Krupin Denver valved implant (7) or a trimmed Baerveldt seton (4). Main Outcome Measures: Vision, IOP, and need for further glaucoma medicatio n or glaucoma surgery were measured. Results: One- and 2-year life-table success rates (either complete or quali fied success) were 82% and 73%, respectively, defining success as final IOP of 21 mmHg or less without need for further glaucoma surgery and no loss o f visual acuity. Half of the successful eyes required antiglaucoma medicati on. Conclusions: Silastic drainage implants may be a viable option in the treat ment of complicated glaucoma after retinal surgery.
