Optic neuritis following Varicella zoster vaccination: Report of two cases

Abstract

Two women presented at our clinic with vision blurring following Varicella zoster virus (VZV) vaccination, 3 weeks and 1 week ago. Ophthalmologic examination and magnetic resonance imaging revealed bilateral and unilateral optic neuritis, respectively. One patient had a history of optic neuritis in the fellow eye 33 years ago without recurrence since then. Both patients completely recovered after treatment with high dose intravenous methylprednisolone followed by a tapered dose of oral prednisolone. This is the first report of optic neuritis occurring in relation to VZV vaccination.
