One-year outcome of cystoid macular degeneration in central serous chorioretinopathy

Abstract

Purpose: To study structural and functional outcomes of cystoid macular degeneration (CMD) in chronic central serous chorioretinopathy (CSCR). Methods: This retrospective study included 26 eyes having chronic CSCR with CMD who underwent either observation, photodynamic therapy (PDT), micropulse laser, or eplerenone therapy. Various optical coherence tomography parameters were analyzed at baseline and 1 year. Results: Number of eyes that maintained or gained vision after treatment was 63.1%, compared to a loss of 2.1 ± 1.1 lines in observation group. Sub-foveal large choroidal vessel responded to PDT ( p = 0.03); while CMT ( p = 0.035) and intra-retinal cystoid spaces (0.037) responded to eplerenone. Longer duration of the symptoms and round cystoid spaces were associated with a decrease in CMT ( p = 0.03) and decrease in cystoid spaces size ( p = 0.02) respectively on follow up. Conclusion: Treatment of eyes with CMD prevents further deterioration of vision. Round configuration of intra-retinal cystoid space has a better anatomical outcome.
