A visual field and fundus autofluorescence photograph of the right eye of an asymptomatic 26 year old man seen for routine optometric evaluation are shown. The yellow arrows highlight areas of increased lipofuscin in the retinal pigment epithelium. The photoreceptors are damaged, producing the paracecal scotoma. The picture is consistent with acute zonal occult outer retinopathy, a suspected autoimmune condition with unknown triggers. He will be serially monitored.
