Abstract

PURPOSE
We present a case of acute zonal occult outer retinopathy (AZOOR) that has not been reported in Korea. METHODS: A 26-year-old female with photopsia and visual field defect in the left eye was referred to our hospital. There were no fundus abnormalities to explain the visual field defect. Electroretinography, indocyanine green angiography, neurologic examination, cerebrospinal fluid tapping and brain magnetic resonance imaging were performed for further evaluation. RESULTS: Visual acuity was 20/20 in both eyes. Visual field examination revealed a peripheral scotoma in the right eye and marked constriction of visual field in the left eye. Electroretinography showed normal response in the right eye and no response in the left eye. There was an afferent pupillary defect in the left eye and vitreous cells in both eyes. Indocyanine green angiography, neurologic examination, cerebrospinal fluid tapping and brain magnetic resonance imaging showed no abnormal findings. CONCLUSIONS: The possibility of AZOOR should be considered in a patient with photopsia, visual field defect, acute loss of outer retinal function confirmed with electroretinography, and minimal or no fundus and angiographic changes, especially in a young woman.
