Dor (Lyons): Optic neuritis in infectious diseases and particularly mumps. Dor found optic neuritis in a series of cases of epidemic parotitis. This occurrence is not infrequent in military hospitals when there are epidemics of mumps. In general the prognosis is favorable, yet in exceptional cases atrophy of the nerve results. The treatment consists in the use of purgatives and diuretics.
