Intracranial optic nerve infarction from subdural hematoma. Clinical and neuropathological findings.

A 60-year-old man fell; a subdural hematoma developed and he lost consciousness. Visual evoked potentials demonstrated a total conduction block in the left optic nerve and slowed conduction on stimulation of the right eye. He died four weeks later, and necropsy showed focal infarcts in the intracranial portion of both optic nerves.
