Bilateral neuropathy of the optic nerve as a complication of mumps

: Mumps belongs to children viral diseases. However, it rather seldom has general complications, either of internal organs or of the central nervous system. The authors present a case of a 10-year-old girl who two weeks after an uncomplicated mumps had bilateral optic nerve neuropathy. Her visual acuity was low and visual fields were constricted. The symptoms disappeared after 8 days without any treatment. But because of a possibility of optic neuritis the girl was treated with oral steroids. She is still observed in our clinic and still shows pathological changes in static computer perimetry.
