PURPOSE OF REVIEW: Over the past two decades, the ophthalmic manifestations of West Nile virus have been more clearly established in the literature. This review aims to summarize its diagnosis and pathogenesis, with a focus on its clinical appearance, characteristic imaging features, and management.
RECENT FINDINGS: Ocular manifestations of West Nile virus present early in the disease course and are more common in cases with severe neurological involvement. The use of optical coherence tomography (OCT), optical coherence tomography angiography (OCT-A), fundus autofluorescence (FAF), fluorescein angiogram (FA), and indocyanine green angiography (ICGA) can aid in its diagnosis and management.
SUMMARY: West Nile virus infection may present with ocular findings that include anterior uveitis, vitritis, retinitis, chorioretinitis, and optic neuropathy; visual prognosis can range from excellent to poor depending on severity of involvement and the presence of secondary complications, such as occlusive vasculitis and macular ischemia. Diagnosis may be aided by multimodal imaging assessment. The ophthalmologist should have a high clinical suspicion for ocular involvement in cases of severe systemic disease.
