High-speed, ultra-high-resolution optical coherence tomography of acute macular neuroretinopathy

Acute macular neuroretinopathy (AMN) is a rare, macular disorder of unknown aetiology. Patients with AMN are typically young women who present with paracentral scotomata in one or both eyes corresponding to red wedge-shaped parafoveal lesions. The retinal location of the lesion in patients with AMN is not clear. High-speed, ultra-high-resolution optical coherence tomography (hsUHR-OCT) is an investigational research prototype instrument capable of producing cross-sectional images of the retina; it supports an axial resolution of about 3.5 μm compared with about 10 μm in Stratus OCT (Dublin, California, USA)1 which enables enhanced imaging of intraretinal morphology including photoreceptor inner segments, outer segments and the external limiting membrane.2 We report a patient with AMN who underwent imaging with hsUHR-OCT suggesting …
