title: Optic neuritis due to acquired toxoplasmosis.
abstract: A pediatric patient with well documented acquired toxoplasmic optic neuritis is presented. Use of immunoglobulin M immunofluorescent antibody studies allow easier identification of recently acquired toxoplasmosis. Toxoplasmic optic neuritis and retinitis should be considered along with toxoplasmic meningitis or encephalitis as complications of acquired toxoplasmosis. Therapy is available which may decrease the duration of visual symptomatology and reduce residual visual impairment.
