Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

The patients with Idiopathic intracranial hypertension (IIH)
33 patients who applied to the neurology clinic with the pre-diagnosis of IIH were performed lumbar puncture. 25 of them diagnosed with IIH. Optic nerve sheath diameter was measured by optic ultrasonography from both eyes before and after the LP.
