PURPOSE: To assess the efficacy and safety of a glaucoma procedure to control intraocular pressure (IOP) using the adjustable eyeWatch glaucoma drainage device compared with Ahmed glaucoma valve (AGV) in refractory glaucoma. PATIENTS AND METHODS: Monocentric, retrospective, comparative clinical trial. Patients suffering from refractory glaucoma after failed surgeries and requiring a further glaucoma procedure including an aqueous shunt were enrolled in this study. The first group AGV included patients with an AGV. The second group eW-B included patients receiving an eyeWatch used in connection with a Baerveldt glaucoma implant. The primary outcome was the success rate, defined as an IOP≤16 mm Hg and reduction of >20% from baseline, and IOP≥5 mm Hg. Secondary outcomes were mean IOP, number of antiglaucoma medications, visual acuity, number and type of complications. RESULTS: Twenty-one patients were included. The mean follow-up time was 13.2±3.4 months. Mean IOP decreased from 24.8±9.0 mm Hg before surgery to 13.8±3.6 mm Hg at 12 months for group AGV, and 27.3±7.0 to 12.8±2.4 mm Hg for group eW-B, respectively (P<0.05). Mean number of glaucoma medications decreased from 3.0±0.7 before surgery to 0.3±0.7 at last control for group AGV, and 2.9±0.8 before surgery to 0.2±0.4 for group eW-B, respectively (P<0.05). The complete and overall success rates were 50% and 58% for group AGV, and 67% and 89% for group eW-B, respectively. CONCLUSIONS: The postoperative adjustability of the eyeWatch is believed to help with getting fewer complications and better IOP management whereas AGV cannot be adjusted postoperatively.
