Atypical acute fovealitis in COVID-19 context

Purpose: To describe the clinical and multimodal imaging findings, including optical coherence tomography (OCT), and OCT angiography (OCTA) in a case presenting with acute fovealitis after COVID-19 infection, and its differential diagnosis. Observations: A 39-year-old man presenting with acute central metamorphopsia in his right eye (OD) right after positive test for COVID-19 underwent comprehensive ophthalmic examination, including best corrected visual acuity (BCVA), color fundus (CF) examination, optical coherence tomography (OCT), OCT angiography (OCTA), fundus autofluorescence (FAF) and fluorescein angiography (FA). Baseline BCVA was 20/40 in his OD and fundus examination showed small inferior juxtafoveal hemorrhages with no other vascular abnormalities or peripheral changes. The OCT B-scans revealed a central focal defect of the ellipsoid and interdigitation zones associated with foveal and perifoveal columnar hyperreflectivities involving the photoreceptor layers, the external limiting membrane and outer nuclear layer up to the outer plexiform layer with preservation of the retinal pigment epithelium-Bruch's membrane complex. Both FAF and FA images were unremarkable. Over three months follow-up, the findings progressively resolved, and BCVA improved to 20/20. Conclusions and importance: The presence of hyperreflective material at the fovea in association with adjacent hemorrhages, the absence of alterations of the retinal pigment epithelium in OCT, OCTA, FAF and FA suggested the diagnosis of acute fovealitis in COVID-19 context. The presence of these findings highlights the importance of detailed ophthalmic evaluation in symptomatic patients with COVID-19 positive test.
