    To describe a series of patients exhibiting annular retinal pigment epithelial (RPE) lesions in the context of chronic central serous chorioretinopathy. Retrospective comparative case series. Consecutive patients with chronic central serous chorioretinopathy were identified from the clinical practices of 3 retina specialists. A subset of patients exhibiting annular RPE lesions on fundus autofluorescence was included for chart review and examination of multimodal imaging (study group). Patients with alternative etiologies for neurosensory detachment or pigment epitheliopathy were excluded. A second consecutive cohort of patients, with acute central serous chorioretinopathy, was also examined for the presence of annular lesions (comparative group). Sixty-seven patients with chronic central serous chorioretinopathy were identified. Fourteen eyes of 12 patients exhibited annular lesions (study eyes). Mean visual acuity of study eyes was 20/27 (logMAR 0.13, SD 0.11). Annular lesions were composed of hyperautofluorescent stellate lesions arranged in an open or closed ring with intervening foci of punctate hypoautofluorescence. Optical coherence tomography showed RPE hyperplasia at the perimeters of annular lesions with loss of ellipsoid reflectivity and preserved RPE at the lesion center. Annular lesions were confined to the posterior poles and appeared to have developed at the margins of chronic neurosensory detachment. Forty-three eyes of 30 patients with acute central serous chorioretinopathy comprised the comparative group and none of these eyes exhibited annular lesions. Annular lesions occur in up to a fifth of patients with chronic central serous chorioretinopathy but carry a relatively good visual prognosis. Curvilinear RPE figures and demarcation lines are seen in various retinal conditions but the characteristics of annular lesions described here suggest that they are specific to chronic central serous chorioretinopathy.
