Acute zonal occult outer retinopathy: optical coherence tomography angiography findings and treatment response

Acute zonal occult outer retinopathy (AZOOR) is a rare condition primarily affecting the outer retina based on electrophysiologic studies. In addition to characteristic fundus appearance, spectral domain optical coherence tomography and fundus autofluorescence are unique in diagnosing AZOOR. There are a few reports on optical coherence tomography anjiography (OCTA) in AZOOR disease. In this report, we present a case using multimodal imaging including OCTA and treatment response to combined systemic antiviral, antiinflammatory, and immunosuppressive drugs. En-face OCTA outer retinal slab may provide useful tips for diagnosis and treatment response.
