Objective This study aims to explore the predictive value of noninvasive ICP waveform analysis (nICPw) as an adjunctive diagnostic and monitoring tool in patients diagnosed with IIH.

Background Idiopathic Intracranial Hypertension (IIH) is characterized by elevated intracranial pressure (ICP) without an identifiable cause, often leading to optic nerve sheath distension and visual impairment. The diagnosis and management of this condition necessitate invasive interventions.

Design/Methods We gathered data on the P2/P1 ratio, time-to-peak (TTP), and the standard deviation (±) from a cohort of 10 patients with a previous diagnosis of IIH. Data collection occurred in two positions: lying down, and at a 30-degree incline.

Results The P2/P1 ratios while lying down, and at a 30-degree incline were 1.21 (±0.19) and 1.38 (±0.32) respectively. TTP values in patients with shunt dysfunction were 23.3 (±7.05), and 26.01 (±3.74) while lying down, and at a 30-degree incline, respectively.

Conclusions Our findings suggest that nICPw data from this patient population could serve as a valuable tool for establishing baseline values. A crucial next step would involve comparing these measurements with those of healthy individuals lacking shunts. It's important to note that while our study revealed similar overall readings, the establishment of baseline values should be tailored to each patient.
