Posterior polar annular and hemispheric choroidal and retinal dystrophy: Optical coherence tomographic angiography description of a rare case.

Abstract

Posterior polar annual choroidal dystrophy is a rare disease which affects the retina and choroid in an annular pattern. Our patient was referred to us a case of atypical retinitis pigmentosa. Fundus examination showed a normal optic disc, normal arterioles, and no bone spicules. The right eye showed a hemispheric pattern and the left eye showed an annular pattern of retinal and choroidal dystrophy. We describe the retinal and choroidal angiographic features of this case by optical coherence angiography.
