Evaluation of the patients diagnosed as idiopathic intracranial hypertension with and without papilledema visual pathways by analysis of visual evoked potential.

Idiopathic intracranial hypertension (IIH) is a clinical syndrome characterized by increased intracranial pressure in the absence of clinical, laboratory, or radiological findings of space-occupying lesion in the cranium. Papilledema is found in majority of the patients with IIH while it is absent in only about 5-6% of the patients. Our primary objective was to evaluate the patients with IIH with (n: 45) and without (n: 15) papilledema using cranial MRI and VEP analyses and to compare the obtained results.
