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

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.
