Acute Macular Neuroretinopathy: An Overview
Acute macular neuroretinopathy (AMN) is a condition that was first described in a four- patient case-series by Bos and Deutman in 1975. It is commonly classed as one of the white-dot syndromes, a group of inflammatory chorioretinopathies characterised by multiple focal chorioretinal lesions seen on slit-lamp fundoscopy. AMN is an uncommon condition known to generally affect young healthy Caucasian females 20-40 years old and is associated with a spectrum from transient to longer-term visual disturbance. The commonest presentation of AMN is one or more wedge-shaped paracentral scotomas of acute to subacute onset, developing over days to weeks, with patients also known to variably report a decline in visual acuity, metamorphopsia, and floaters. One or both eyes may be affected.
