Cystoid Retinal Degeneration in Chronic Central Serous Chorioretinopathy: A Rare Optical Coherence Tomography Finding



Purpose: To report cystoid retinal degeneration (CRD) in two cases of chronic central serous chorioretinopathy (CSCR) using optical coherence tomography (OCT).

Methods: Case report. Two patients with chronic CSCR having metamorphosia and blurred vision for longer than 6 months were evaluated.

Results: OCT showed multiple intraretinal cysts in the outer plexiform and the outer nuclear layers of retina, concomitant subretinal fluid with brush-border pattern in 3 eyes of 2 patients. Retinal cystoid changes were located in the fovea in 1 eye and in the extrafoveal area in 2 eyes. Visual acuity was higher than 20/200 in all eyes. At the last examination, visual acuity and cystoid space on OCT images did not change.

Conclusion: Cystoid retinal degeneration is a rare complication of chronic CSCR and characteristically located in the outer layers of the retina on OCT. Visual prognosis depends on localization of CRD and duration of the disease
