Photodynamic therapy in subfoveal and juxtafoveal idiopathic and postinflammatory choroidal neovascularization

Abstract

To evaluate the efficacy of photodynamic therapy (PDT) in the treatment of idiopathic and inflammatory choroidal neovascularization (CNV). This study represents a non-randomized, multicentre, interventional case series. Sixteen eyes of 16 patients with classic or predominantly classic sub- and juxtafoveal idiopathic CNV and 26 eyes of 24 patients with classic or predominantly classic sub- and juxtafoveal CNV secondary to inflammatory conditions were treated with PDT with verteporfin. Best corrected visual acuity (BCVA) before and after PDT, the number of lines gained or lost and the number of PDT sessions were analysed. The mean follow-up periods were 20 months (SD 11) and 16 months (SD 9) for the idiopathic and inflammatory groups, respectively. The mean BCVA in idiopathic CNV changed from 0.63 logMAR (SD 0.37) before treatment to 0.82 logMAR (SD 0.43) after treatment (p = 0.16; Student's t-test paired data). The number of treatments performed averaged 2.1 (range 1-4, SD 0.9). The mean BCVA in postinflammatory CNV changed from 0.60 logMAR (SD 0.4) before treatment to 0.57 logMAR (SD 0.6) after treatment (p = 0.79; Student's t-test paired data). The mean number of treatments was 2.6 (range 1-6, SD 1.2). Photodynamic therapy with verteporfin may be useful in stabilizing BCVA in patients with sub- and juxtafoveal postinflammatory CNV and subfoveal idiopathic CNV.
