Purpose To describe clinical characteristics and response to verteporfin therapy ( PDT ) in eyes with retinal pigment epithelium detachment ( PED ) in the absence of primary disease other than characteristics compatible with central serous chorioretinopathy ( CSC ). Methods Retrospective review of 634 consecutive patients diagnosed with isolated PED or CSC in one or both eyes in the period from 2007 to 2014 at a single institution. Results Pigment epithelium detachment (PED) in the absence of primary pathology other than angiographic choroidal hyperpermeability in the incident or fellow eye or manifest CSC in the fellow eye was found in 22 eyes in 19 patients. Follow‐up ranged from 4 to 61 months. Five of 19 patients (26%) had classic CSC in the fellow eye. Transition from isolated PED to manifest CSC in the eye with PED was observed in seven eyes (33%) over a median untreated period of observation of 11 months (range, 1–32 months). A single session of PDT followed up 1–6 months later showed full resolution of the PED in seven (78%) of nine eyes. Of the 13 untreated eyes, five eyes (38%) underwent spontaneous resolution of the PED . Conclusion Fellow‐eye findings, conversion to CSC , resolution of PED after PDT or, less commonly, spontaneously support that isolated PED is a manifestation of CSC that represents an intermediate stage between pachychoroid and classic CSC . The chance of experiencing resolution of the PED was roughly twice as high with PDT as with untreated observation.
