Enhanced depth imaging OCT and indocyanine green angiography changes in acute macular neuroretinopathy

The authors describe indocyanine green angiography (ICGA) and enhanced depth imaging optical coherence tomography (EDI-OCT) in a 46-year-old male patient with acute macular neuroretinopathy (AMN). The chief complaint was decreasing visual acuity and metamorphopsia in both eyes of 1-month duration. Visual field assessment, fluorescein angiography, OCT, ICGA, and EDI-OCT were performed initially and at 3 months. ICGA showed choroidal vascular hyperpermeability and punctuate choroidal hyperfluorescent spots, especially in the left eye. EDI-OCT showed increased choroidal macular thickness, with inner and outer retinal layers affected. EDI-OCT and ICGA reveal that both the choroid and retina can be affected in AMN; however, the primary pathology and localization of depth of involvement in AMN remains unclear.
