To investigate morphologic changes in the asymptomatic fellow eye of central serous chorioretinopathy (CSC) using spectral domain optical coherence tomography (SD OCT).

The present retrospective study included 55 asymptomatic fellow eyes of 55 patients with acute CSC. All patients underwent SD OCT, fluorescein angiography (FA), and indocyanine green angiography (ICGA), and the results were analyzed.

Sixteen eyes (29.1 %) with normal FA also showed normal SD OCT; however, 70% of the eyes showed choroidal hyperpermeability or punctate hyperfluorescent spots on ICGA. Window defects on FA were observed in 25 eyes (45.5%), and they were represented as a corrugation or bump in the retinal pigment epithelium (RPE) on SD OCT. Retinal pigment epithelial detachments (PEDs) were observed in six eyes (10.9 %) on FA and were represented as PEDs on SD OCT. Leakages on FA were observed in ten eyes (18.2%) and were represented as normal, serous retinal detachment, and a corrugation or bump of RPE on SD OCT.

Greater information regarding morphologic changes and pathophysiology of CSC can be obtained by investigating SD OCT findings in the asymptomatic fellow eyes of acute CSC.
