Azoor Acute Zonal Ocular Outer Retinitis: A Case Report and Literature Review

Abstract

Acute zonal ocular outer retinopathy (AZOOR) is a rare disease, usually manifested by persistent photopsia, reduced visual acuity, asymmetric visual field loss. A 46 years old female patient presented to our department for investigation of a slowly progressive decline in visual acuity over several years with no other associated signs. Best corrected visual acuity was 1/10 in the right eye and 8/10 in the left eye; fundoscopic examination revealed an extensive, poorly demarcated peripapillary depigmentation halo with scattered pigment clots, the oct showed atrophy of the outer retina, including interruption of the ellipsoid zone and the outer nuclear layer in the affected areas, with foveal sparing. The patient was treated with steroidal anti-inflammatory drugs, but with no obvious response.
