Abstract
Demyelination is the most common cause of optic neuritis. Typical optic neuritis needs intravenous steroids followed by tapering dose oral steroids. Atypical optic neuritis entails clinical manifestations that deviate from the classic pattern of features. Atypical ON can have devastating visual results if not treated in a timely fashion. Thus, it is critical that cases of atypical optic neuritis are recognized early to initiate proper treatment and preserve vision. Our case presented as an atypical case of optic neuritis. The patient had painless onset and was not responding to steroids, but presentation in the other eye and systemic administration of antivirals helped in management of this case.
