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...

BACKGROUND: Acute zonal occult outer retinopathy (AZOOR) is a disease of unknown etiology in young or middle-aged patients that is characterized by acute loss of one or more zones of outer retinal function, photopsia, minimal initial ophthalmoscopic changes, and electroretinographic abnormalities. AZOOR may represent part of the spectrum of a single disease, the so-called AZOOR complex. In contrast with most other ocular diseases that may be part of this AZOOR complex, AZOOR has not, to our knowledge, been reported in association with choroidal neovascularization (CNV)...
