[Progressive scotoma with perception of photopsia]

Acute annular outer retinopathy (AAOR) is a very rare variant of acute zonal occult outer retinopathy (AZOOR). Both variants are characterized by the perception of a progressive visual field defect and can be accompanied by photopsia. In contrast to AZOOR, a progressive whitish and annular demarcation of the involved retina is observed in AAOR using ophthalmoscopy. Optical coherence tomography (OCT) reveals morphological changes predominantly in the outer retinal layers. Although there is no proof of an effective therapy, in the case presented here further progression could be stopped by a combination of antiviral and immunosuppressive therapy.
