Ocular manifestations of West Nile virus

PURPOSE OF REVIEW: To review the ocular findings of patients with West Nile Virus. RECENT FINDINGS: Ocular findings have included multifocal choroiditis, vitritis, intraretinal hemorrhages, iritis, keratic precipitates, optic neuritis, branch retinal artery occlusions, and chorioretinal scarring in a case of intrauterine transmission. SUMMARY: The ocular findings associated with WNV appear to be self-limited. All the adults reported had improved vision and most had resolution of inflammation, with or without topical steroids, over the course of a few months. It may be reasonable to obtain West Nile Virus titers in any patient presenting with the above findings and systemic illness, especially from an endemic area.
