Photodynamic therapy for variant central serous chorioretinopathy: efficacy and side effects

Abstract

Background: Retinal pigment epithelial detachment (PED) is a recognised associated finding in central serous chorioretinopathy (CSC). We report our experience in treating patients using photodynamic therapy (PDT) in a variant of chronic CSC that presents with only an isolated PED. We present long-term follow-up data and novel observations on the pattern of retinal pigment epithelium (RPE) changes seen after treatment.

Methods: Retrospective case series.

Results and discussion: CSC with subfoveal PED can be associated with a poor visual prognosis especially when the PED becomes chronic. PDT has been used to treat typical CSC with good outcomes. Three eyes in 3 patients were successfully treated with PDT, using the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy protocol. However, marked RPE disturbance was observed after treatment directly overlying the areas of brisk choroidal hyperpermeability.
