Abstract

PURPOSE
To report a case of chorioretinal atrophy after photodynamic therapy to subfoveal choroidal neovascular membrane. METHODS: We followed up the photodynamic treatment to a 57-year-old woman who complained of the falling of vision in her right eye for 2 months and was diagnosed with subfoveal choroidal neovascular membrane at our institution. Since the size of neovascular membrane increased 3 month after the first photodynamic treatment, the patient underwent retreatment. Concentric chorioretinal atrophy developed around the laser applied site 3 months after retreatment, and enlargement of the atrophy area occurred 2 years later. In multifocal electroretinography, the retinal function of the chorioretinal atrophic eye was not decreased compared with the other eye. RESULTS: The choroids collateral circulation damage or direct drug photochemical effect was thought to be the cause of the chorioretinal atrophy after photodynamic treatment at the laser applied site but there is no functional decline of the atrophic retina.
