Purpose: to describe multimodal imaging and electrophysiology of multiple evanescent white dot syndrome (MEWDS) concomitant with COVID-19 infection in a patient on BRAF (B Rapidly Accelerated Fibrosarcoma) and MEK (Mitogen-activated Protein Kinase) inhibitors.
Methods: observational case report and literature review.
Results: a 37-year-old woman affected by cutaneous melanoma on BRAF and MEK inhibitors developed visual symptoms in the right eye simultaneously with a SARS-COV-2 infection. The right eye visual acuity was hand movement, and clinical examination disclosed vitreous cells, yellow-white retinal spots, and macular yellowish material. Fundus autofluorescence and angiograms were consistent with MEWDS. Angiograms, optical coherence tomography, and optical coherence tomography angiography revealed a macular choroidal neovascular membrane. The infectious and inflammatory work-up was negative. Electrodiagnostic tests revealed cone dysfunction. MEWDS resolved and anti-VEGF treatment allowed partial vision recovery.
Conclusion: the case illustrates the association of MEWDS and choroidal neovascularization developing after COVID-19 infection in the setting of immunotherapy.
