Abstract
West Nile virus (WNV) infection is a worldwide zoonosis due to a Flavivirus transmitted by a mosquito vector. Most human infections are subclinical or manifest as febrile illness, but a small proportion of patients may develop severe neurologic disease (meningoencephalitis), frequently associated with advanced age and diabetes. A bilateral multifocal chorioretinitis is the most common ocular manifestation of WNV infection, occurring in nearly 80 % of patients with severe systemic disease. Other ophthalmologic findings include anterior uveitis, retinal vasculitis, optic neuritis, and congenital chorioretinal scarring. WNV-associated ocular involvement usually has a self-limited course. There is no effective antiviral therapy against WNV infection and prevention is the mainstay of WNV infection control.
