Abstract

Acute zonal occult outer retinopathy (AZOOR) is a group of diseases observed in one or both eyes with damages to broad zones of the outer retina. Initial symptoms include photopsia, visual field defects, and sometimes an enlarged blind spot. On initial presentation, the central visual acuity may not be affected, and the fundus may appear normal, easily leading to the misdiagnosis of AZOOR. The visual field examination plays an irreplaceable role in the diagnosis and follow-up observation of the disease. Two typical cases have been selected to elucidate AZOOR in this section.
