Azoor: Acute Zonal Occute Outer retinopathy associated with autoimmune disease

Abstract

Acute zonal occult external retinopathy (AZOOR) was first described by Gass in 1993 as a syndrome with rapid loss of one or more large areas of the external retinal segments. Male, 35 years, with Crohn's disease complaining of occasional eye pain and right eye nictalopia since childhood. In regular use of azathioprine and mesalazine. better visual acuity 20/20 OU. At fundoscopy, hyperpigmented lesions in the right temporal arcade of the right eye, in trellis, accompanying local vasculature. After exclusion of differential diagnoses, Azoor's diagnosis was reached. Azoor is an idiopathic syndrome characterized by an acute onset of photopsy, scotoma or both and is typically associated with a persistent loss of visual function involving one or more areas of the external retina. Despite classic photopsy symptoms, the patient in question had an atypical clinical presentation. We describe a case of a peripheral male with choroidal thinning and associated autoimmune disease. Thus, we believe that further investigation is necessary to verify the etiology of choroidal alteration and its association with the specific disease.
