Acute macular neuroretinopathy associated with migraine.

Abstract

Acute macular neuroretinopathy (AMN) is an uncommon entity that affects the outer layer of the retina and usually presents itself as an acute paracentral scotoma. It is mostly seen in young women and the course is usually self-limited. The diagnosis is established by a multimodal image, with optical coherence tomography (OCT) being the preferred technique. The origin is thought to be linked to a possible dysregulation in the flow of the deep vascular plexus of the retina or the choriocapillaris. A clinical case of an AMN in a young woman associated with a migraine attack is presented, highlighting the importance of considering this disease in the differential diagnosis of visual disorders associated with migraines. A physiological and pathological basis between migraine and NMA is suggested.
