Answer

Kesler et al used VEP studies to assess 20 patients with chronic idiopathic intracranial hypertension and found that 55% of the patients had prolonged VEPs. [21] These latencies tended to correlate best with visual field deficits, but other clinical findings were less congruent. The prolongation of the latencies suggested demyelination as the pathogenic process occurring in these individuals.
