Pigmented Paravenous Retinochoroidal Atrophy(PPRCA)

ABSTRACT

Pigmented Paravenous Retinochoroidal Atrophy(PPRCA) is a type of pigmentary retinopathy that affects mostly both eyes symmetrically without inheritance. The PPRCA occurs in both progressive and non-progressive forms, but most cases are non-progressive forms. The fundus appearance of PPRCA is characteristic, with peripapillary pigmentary change as well as areas of retinochoroidal atrophy adjacent to the perivenular pigmentary change. The authors have studied a case of PPRCA which was diagnosed through the characteristic fundus appearance and other ophthalmological examinations.
