Multimodal Imaging of Acute Foveolitis following COVID-19 Vaccination.

PURPOSE To report a case of unilateral acute foveolitis following COVID-19 vaccination. METHODS A case report. RESULTS A 24-year-old woman developed a sudden blurring of vision in the left eye (LE) 5 days after receiving the first dose of COVID-19 vaccine. Examination of the LE showed a visual acuity at 20/40, 2+ cells in the vitreous, and a small yellow-orange foveal subretinal lesion. Late-phase fluorescein angiography showed a mild diffuse retinal vascular leakage and a faint foveal hyperfluorescence. ICG angiography showed in the late-phase hypofluorescence of the centrofoveal lesion. OCT B-scan demonstrated a conical hyperreflective subfoveal lesion on the retinal pigment epithelium associated with disruption of the outer retinal layers. En-face OCT revealed granular hyperreflective specks mainly in the inner nuclear layer. Work-up results were unremarkable. The patient received oral prednisolone with subsequent full functional and anatomic recovery. CONCLUSION Foveolitis may rarely occur as a complication of COVID-19 vaccination.
