Bilateral Optic Neuritis: A Rare Complication of Mumps.

Mumps is a contagious viral illness that classically presents with fever, parotid gland swelling, headache, and vomiting in unimmunized children. The complications of mumps most commonly include orchitis, pancreatitis, encephalitis, and meningitis. Optic neuritis, which refers to the inflammation of the optic nerve, in rare cases, can present after mumps meningoencephalitis and causes pain in the eye, and a decrease in visual acuity. We report and discuss a case of bilateral optic neuritis following mumps meningoencephalitis in a child. The patient was managed with short-term steroid therapy.
