PURPOSE To evaluate the results of Ahmed glaucoma valve surgery in neovascular glaucoma and control patients. METHODS In this retrospective comparative study, we reviewed 76 eyes of 76 patients, comparing the surgical outcomes in control patients (N=38) to matched neovascular glaucoma patients (N=38). Success was defined as intraocular pressure (IOP) > or =6 mm Hg and < or =21 mm Hg, without ...
