Non-invasive Intracranial Pressure Monitoring in Brain Tumor Patients
Non-invasive Intracranial Pressure Monitoring in Brain Tumor Patients: A Prospective Observational Study of Optic Nerve Sheath Diameter Dynamics
Source: ClinicalTrials.gov · Last updated 16 Dec 2025
Brief summary (registry, in English)
This research protocol focuses on the pre- and post-operative evaluation of ICP using non-invasive methods, particularly in the context of surgery for brain tumor removal. By utilizing ocular ultrasound to measure ONSD and ONSD/ETD ratios, this study hypothesizes that the utility of these parameters in monitoring ICP pre- and post-operative periods could be effective.
