PURPOSE: Acute Macular Neuroretinopathy (AMN) may be the result of deep retinal capillary plexus (DCP) impairment, but its mechanism remains elusive. A recent study has described simultaneous onset of Paracentral Acute Middle Maculopathy (PAMM) and AMN, suggesting a related pathogenic pathway. In this report, we analyze and describe the imaging characteristics of patients with concomitant Central Retinal Artery Occlusion (CRAO) and AMN and suggest a mechanistic pathway to explain this relationship.
OBSERVATIONS: A total of 2 cases of CRAO, arteritic and non arteritic, were included in this report. At initial presentation, outer retinal layers were intact. At the two-week follow-up visit, both cases displayed Henle fiber layer hyperreflectivity and ellipsoid zone disruption consistent with AMN.
CONCLUSIONS: Secondary development of AMN in CRAO is a new finding. DCP ischemia secondary to CRAO may lead to Henle fiber layer disruption, leading to the characteristic findings of AMN.
