Autoimmune Retinopathy Following COVID-19: A Case Report.

PURPOSE

To present a presumed case of non-paraneoplastic autoimmune retinopathy (nPAIR) following COVID-19 in a healthy woman.

METHODS

A single case was evaluated and followed for 32 months.

RESULTS

A healthy 32-year-old woman presented with photopsia and paracentral scotoma (OU) after a recent COVID-19 infection. Past medical history and family history were unremarkable. Her visual acuity was normal (OU). Retinal atrophy, mild disc pallor, and foveal reflex attenuation were observed (OU). Optical coherence tomography (OCT) scans showed outer nuclear layer thinning and ellipsoid zone disruption (OU). The visual field test showed blind spot enlargement and arcuate scotomas (OU). Uveitis workup and underlying malignancy investigations were negative. A diagnosis of nPAIR was presumed. At the time, she refused therapy, and 20 months later, her visual acuity was stable, but there were progressive retinal atrophic changes and visual field constriction. After initiation of glucocorticoids and immunosuppressive therapy, flashing lights completely disappeared, her visual field was stabilized without progression, and OCT scans showed partial recovery of ellipsoid zone.

CONCLUSION

SARS-CoV-2 infection may be a trigger for nPAIR in susceptible individuals, but further research is needed to determine this association.
