Purpose: To report multimodal imaging features of a novel association of non-arteritic anterior ischemic optic neuropathy (NAION), paracentral acute middle maculopathy (PAMM), and cilioretinal artery occlusion (CILRAO).
Methods: A 74-year-old male patient presented complaining of an acute subjective decline in visual acuity in the right eye over the previous days. This patient underwent a comprehensive ophthalmological assessment, including multimodal retinal imaging and visual field test.
Results: The eye examination revealed yellowish optic disc edema in the right eye with peripapillary hemorrhages and a whitish lesion extending from the temporal margin of the optic nerve head towards the macula. Multimodal imaging confirmed the diagnosis of NAION in the right eye. Notably, the structural B-scan and en face OCT images revealed hyperreflective areas in the inner and mid retinal layers, indicating an association with CILRAO and PAMM.
Conclusion: We herein describe the clinical findings of a previously unreported association among NAION, CILRAO and PAMM.
