Backgrounds: Idiopathic intracranial hypertension (IIH); symptoms include headaches, blurred vision and papilledema which may lead to permanent visual loss. Definitive diagnosis of IIH usually requires the measurement of intracranial pressure (ICP) via lumbar puncture (LP) which is an invasive technique. In our study, the relationship between ICP and optic nerve sheath diameters (ONSD) were examined. Thus it was investigated whether optic nerve ultrasonography (USG) is a useful tool instead of LP for the diagnosis of IIH.
Methods: A total of 25 patients who applied to the neurology clinics of Ankara Numune Training and Research Hospital between May 2014 and December 2015 and were diagnosed with IIH were included in the study. The control group consisted of 22 individuals who applied with other complaints than headaches. ONSD was measured from both eyes before and after the LP. After pre-LP measurements were taken, opening and closing CSF (cerebrospinal fluid) pressure was measured. In the control group, ONSD was measured with optic USG.
