Retinal microangiopathy in pigmented paravenous chorioretinal atrophy.

This report describes an atypical case of pigmented paravenous chorioretinal atrophy, associated with focal progressive peripheral retinal microangiopathy, in a 51-year-old black female. The eyes were asymmetrically involved. Although several cases have been reported with typical features of this uncommon entity, none of them have been known to be associated with retinal microangiopathy. The occurrence of such microangiopathy supports the hypothesis that damage to the retinal photoreceptors may induce retinal microangiopathy, as suggested in other clinical and experimental studies.
