Acute macular neuroretinopathy: contribution of spectral-domain optical coherence tomography and multifocal ERG

Abstract

Background: Acute macular neuroretinopathy is a rare disease which occurs in young women and causes sudden paracentral scotoma and typical reddish-brown macular lesions.

Material and methods: We report two cases of young women suffering from acute macular neuroretinopathy which we observed with spectral-domain Spectralis HRA-OCT and multifocal ERG at 3 and 7 months.

Results: Imaging revealed an early hyper-reflectivity of the photoreceptor layer, which changed into hyporeflectivity in the first week and remained the same in the following months, whereas visual field improved.

Conclusions: Our findings show involvement primarly of the outer retina, and confirm OCT and mf ERG as important tools for diagnosis and follow-up of pathologic changes in AMNR, as other diagnostic tests often remain normal.
