Influenza-Induced Acute Macular Neuroretinopathy With Cerebral Involvement in a Ten-Year-Old Boy.
Ophthalmic Surgery, Lasers & Imaging Retina
A 10-year-old male presented with 1-week duration of painless bilateral central vision loss after having been diagnosed with influenza A. Optical coherence tomography revealed superficial retinal nerve fiber layer infarcts, hyperreflectivity of the inner nuclear layer consistent with paracentral acute middle maculopathy (PAMM), and outer nuclear layer hyperreflectivity and disruption of the ellipsoid zone suggesting acute macular neuroretinopathy (AMN). Brain MRI revealed enhancement of the right basal ganglia consistent with focal encephalitis. He was diagnosed with presumed influenza-induced leukocytoclastic vasculitis (LCV) and treated with intravenous steroids. Influenza-induced LCV is a rare phenomenon and can present with AMN, PAMM, and encephalitis. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:293-297.].
