Long-Term Visual Field Outcomes after failed trabeculectomy: Same site Trabeculectomy versus Ahmed Glaucoma Valve Implantation.
PURPOSE To compare visual field (VF) progression rates after repeat trabeculectomy versus Ahmed Glaucoma Valve (AGV) implantation in eyes with prior trabeculectomy failure, and to identify risk factors for postoperative VF deterioration. DESIGN Retrospective clinical cohort study. METHODS Eyes with failed trabecule...
