Abstract
PURPOSE: To describe the clinical and angiographic characteristics of peripheral exudative hemorrhagic chorioretinopathy, an uncommon chorioretinal mass lesion, important for its differential diagnosis to choroidal melanoma, but only rarely described in the literature. DESIGN: Retrospective, institutional chart review. METHODS: Institutional chart review of 45 patients (56 eyes) diagnosed with peripheral exudative hemorrhagic chorioretinopathy to describe the clinical findings and those obtained by fluorescein angiography (FA) and indocyanine green angiography (ICGA), in addition to a review of the histologic findings of an enucleated eye. RESULTS: Peripheral exudative hemorrhagic chorioretinopathy typically was characterized by increased age of the patient (mean, 77 years; range, 60 to 91 years), female preponderance (69%), frequent pigment epithelium detachment, temporal equatorial location, and a highly hemorrhagic and exudative presentation, sometimes extending to the macula. Bilateral involvement (24%) was associated with multiples lesions in the same eye (P < .001) and with nasal extension (P < .001). A neovascular origin was suspected on FA, but was more evident on ICGA. Histologic examination of the enucleated eye did not reveal a neovascular network. CONCLUSIONS: Peripheral exudative hemorrhagic chorioretinopathy is a characteristic peripheral degenerative disorder, frequently with benign outcome, although it can be vision threatening because of hemorrhage or exudation. Clinical features are helpful for its diagnosis. FA and ICGA contribute valuable evidence to the hypothesis of a neovascular origin, but further histologic studies are needed to prove this hypothesis.
