To evaluate the clinical efficacy and safety of the double-plate Ahmed Glaucoma Valve. Multicenter, retrospective observational case series. We reviewed 50 eyes in 50 patients treated with the double-plate Ahmed Glaucoma Valve with mean follow-up of 11.7 ± 7.9 months. Average intraocular pressure was reduced from 36.0 ± 12.4 mm Hg before surgery to 15.8 ± 7.7 mm Hg at the most recent follow-up after surgery ( P < .001). The number of glaucoma medications was decreased from 3.3 ± 0.8 before surgery to 1.4 ± 1.4 after surgery ( P < .001). The percent of success was 76% of eyes at the latest follow-up. Choroidal effusion occurred in four eyes (8%) and did not require surgical treatment in any eye. Despite a poor prognosis group of patients in this study, the double-plate Ahmed Glaucoma Valve was effective in lowering intraocular pressure with a low incidence of complications associated with hypotony.
