Multimodal imaging of type 2 acute macular neuroretinopathy in a young woman

We report a case of type 2 acute macular neuroretinopathy (AMN) that occurred in an otherwise healthy 22-year-old white woman taking oral contraceptives and consuming large quantities of caffeinated coffee. The patient presented with a teardrop-shaped scotoma just inferior to her central vision in her left eye after a recent and significant increase in coffee consumption. A small extrafoveal retinal lesion was present superior to the fovea on pseudocolor fundus photography. Multimodal retinal imaging demonstrated focal disruption of the inner segment-outer segment junction of the photoreceptors with overlying hyperreflectivity at the level of the outer plexiform layer superior to the fovea, consistent with a diagnosis of type 2 AMN. Oral contraceptive use and high caffeine intake may be risk factors for the development of type 2 AMN.
