Serpiginous Choroiditis After COVID-19 Infection.

To present the first case of macular serpiginous choroiditis after COVID-19 infection. A single case was analyzed. A 28-year-old previously healthy man presented with severe unilateral vision loss in the left eye. A fundus examination showed severe atrophic pigmentary changes that corresponded with optical coherence tomography (OCT) findings of a rapidly progressing amoeboid-like lesion disrupting the ellipsoid zone and retinal pigment epithelium. Multimodal imaging, including fundus autofluorescence, OCT angiography, and indocyanine green angiography, was supportive of serpiginous choroiditis. After a comprehensive systemic workup, the diagnosis of macular serpiginous choroiditis was confirmed. No improvement was seen with high-dose steroids; therefore, an immunosuppressive regimen was initiated. An exaggerated choroidal inflammatory response may be triggered by a COVID-19 infection, although causation cannot be inferred. Retinal manifestations should be considered when assessing patients presenting with visual symptoms after COVID-19 infection.
