Idiopathic intracranial hypertension: ocular vestibular evoked myogenic potentials as a new evaluation tool

Patients with idiopathic intracranial hypertension (IIH) have an elevated intracranial pressure (ICP) in absence of any tumor or venous drain disorders. Diagnosis is based on the symptoms of elevated intracranial pressure (ICP) such as papillary edema, elevated cerebrospinal fluid (CSF) pressure in the spinal tap test of >25 cmH2O in absence of pathologic cellular or biochemical results in the spinal tap test, or structural or vascular abnormalities on cerebral MRI. For the clinical management and follow-up of patients with IIH, the possibility of non-invasively monitoring changes in ICP over time could potentially reduce the need for invasive diagnostic lumbar drainages (LD).
