VEP and EEG in cortical blindness: a case with a complicated course.

ABSTRACT

We report a case of cortical blindness secondary to an extensive bilateral occipital ischemic infarct and complicated by the onset of bilateral optic nerve ischemia. We discuss the behavior of the VEP, present--an unusual finding--in the first phase of the occipital ischemic lesion, and the value of the alpha band rhythm in the EEG record.
