Visual Evoked Potentials in
Benign Intracranial Hypertension To Follow up Cerebrospinal Fluid Pressure Murat Aksu, Ömer Soyak, Emel Köseoğlu Visual evoked potentials (VEP) studies are non-invasive method to indicate the function of optic ways by occipital cortex. But they are specially sensitive anterior the optic chiasm. VEP were used in patients with hydrocephalus to monitories the intracranial pressure. Here VEPs are studied in benign intracranial hypertension (BIH) to see the correlation with cerebrospinal fluid (CSF) pressure and VEPs.VEP studied 14 times in two patients with BIH, nine in one and five in other. There were no signs of optic atrophy in both. CSF pressures were measured with lumbar puncture in 30 minutes after VEP studies. As a result there were a weak correlation between CSF pressure and VEPs in patients with BIH. We concluded that VEPs are not useful to follow up the CSF pressure in patients with BIH: |
