Central serous retinopathy (CSR) in acute (a, c, e) and chronic (b, d, f) phases. The borders of the neurosensory detachment in acute CSR are apparent in the fundus photo (a) and demarcated by fluorescein angiography (FA) (c), which shows the classic “smokestack” pattern. A small pigment epithelial detachment (PED; arrow) is present on optical coherence tomography (OCT) (e) with a much larger amount of subretinal fluid. In chronic CSR (d), retinal pigment epithelium changes are present in several locations of the macula, with corresponding areas of leakage and window defects on FA (d)(f) shows a shallow subretinal elevation corresponding to leakage nasal to the fovea with a collapsed underlying PED (arrow).
