Bilateral Optic Neuritis After Influenza Vaccination

Abstract

Optic neuritis is a rare complication of vaccination. We report a 55-year-old woman who presented with bilateral optic neuritis following influenza vaccination. The patient has typical features of acute optic neuritis with acute visual loss, periocular pain, visual defects, full recovery of vision after 6 months, and the absence of deterioration after withdrawal of corticosteroids. Considering the absence of oligoclonal bands in the cerebrospinal fluid analysis and the nonexistence of lesions resembling multiple sclerosis (MS) in cranial magnetic resonance imaging, the case at present does not appear to be associated with MS.
