That inflammation of the optic nerve may be associated with influenza is definitely shown by the literature. But whether the optic neuritis is infectious, toxic or mechanical is uncertain. In the case here reported, apparently there was an acute hydrocephalus and one might conclude that the optic neuritis was due to increase of intracranial pressure, but it seems much more probable that the optic neuritis was a local acute inflammatory reaction to a toxemia which also produced the hydrocephalus and perhaps a more general low-grade encephalitis.
