Abstract
The aim of this study is to investigate fundus autofluorescence (FAF) as well as fluorescein angiography (FA), indocyanine green angiography (IA), and optical coherence tomography (OCT) in a patient with pigmented paravenous chorioretinal atrophy (PPCRA). A funduscopic examination revealed chorioretinal atrophy along the paravenous area in both eyes. A marked bone spicule pigment clumping together with the atrophy was noted left eye. FA and IA showed a window defect and hypofluorescence, respectively, which exclusively corresponds to the atrophic area along the retinal vein area and the optic disc both eyes. FAF revealed geographic hypofluorescence along the paravenous and supranasal retinal areas. Hyperfluorescence was noted, which comparatively surrounded the hypofluorescence in the peripheral paravenous distribution. Hypofluorescence detected by FAF corresponded to the areas of retinal thinning and atrophy detected by OCT and FA. FAF is a useful examination in PPCRA, which can noninvasively demonstrate the distribution of deficit and dysfunction of retinal pigment epithelium.
