Presumed Solitary Circumscribed Retinal Astrocytic Proliferation in the Fovea With OCT Angiography: A Misnomer.

The retinal lesion known as the presumed solitary circumscribed retinal astrocytic proliferation (pSCRAP) is a benign retinal tumor. Although many of the clinical characteristics of the lesion have been described, much about the pathogenesis of this uncommon tumor is not yet known. Here, the authors report a pSCRAP lesion in the fovea with secondary vision loss occurring in middle age. Structural optical coherence tomography (OCT) scans indicate that the lesion arises from the deep retina or retinal pigment epithelium (RPE), whereas OCT angiography characteristics of the lesion show a lack of intrinsic or paralesional vascular flow, indicating that this lesion is fibrous and likely derived from the RPE or deep retina and not the retinal astrocytes.
