Acute macular neuroretinopathy (AMN) is a rare disease of the outer retina, most commonly presenting with a central or paracentral scotoma, wedge-shaped foveal lesions and hyper-reflective lesions, followed by thinning at the inner segment-outer segment junction. Patients report central/ paracentral scotomas which correlate with visual field defects as detected by Amsler grid and automated static visual field testing. The case presented in this paper demonstrates the diagnosis of AMN in the absence of the full range of disease markers and highlights the importance of high density optical coherence tomography scanning in aiding the diagnoses of previously missed clinical conditions.
