A Case of Acute Macular Neuroretinopathy Associated with Acute Optic Neuritis

Acute optic neuritis (AON) is a common inflammatory optic neuropathy. Demyelinating AON is the most common type. AON is associated with inner nuclear layer thickening and microcystic macular edema on optical coherence tomography (OCT), independently of demyelination. Conversely, acute macular neuroretinopathy (AMN) type 2 is a rare outer retinal disorder, with suspected vascular etiology mainly affecting the deep capillary plexus, resulted with thinning of the outer nuclear layer. Both entities most commonly affect young Caucasian women. We present a case of AMN associated with AON.
