    Fundus autofluorescence and optical coherence tomography findings in pigmented paravenous retinochoroidal atrophy

    Pigmented paravenous retinochoroidal atrophy (PPRCA) is a rare ocular disease with unknown etiology characterized by bilateral retinal pigment epithelium (RPE) and choroidal atrophy along retinal veins usually found incidentally during an eye examination. 1 In the past, fluorescein angiography (FA), electrophysiologic tests, and visual field testing have helped in the diagnosis. 1–3 Noninvasive imaging techniques including fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SD-OCT) are now available to assist retina specialists in the diagnosis of retinal degenerations, dystrophies, 4,5 and also drug toxicity.
