Late-onset visual decline following successful treatment of subfoveal choroidal neovascularisation with photodynamic therapy

Abstract

Photodynamic therapy (PDT) has been shown in large studies to be capable of achieving closure of choroidal neovascularization (CNV), thereby resulting in stabilization of visual acuity. We report a series of four patients with classic CNV treated with PDT with good initial result but subsequent severe visual loss that may be related to a change in the morphology of the subretinal scar. © 2006 Nature Publishing Group All rights reserved.
