The comparison of non-invasive ICPsnapshot and non-invasive ICPmonitoring methods on healthy volunteer: A pilot study.

Intracranial pressure (ICP) monitoring is essential in management and in treatment of neurosurgical, neurological, and in some cases of ophthalmological patients. However, ICP monitoring is not suitable for a wider range of patient groups due to the invasiveness. Non-invasive ICP estimation would also be valuable in other clinical situations where patients are conscious (nephrology, aerospace, and sport medicine, etc.). In case of ophthalmology, ICP and intraocular pressure is considered to be two key factors for precise and patient individual normal tension and high-tension glaucoma diagnosis. Here, we have compared two different non-invasive ICP measurement methods. After snapshot calibration by non-invasive ICP snapshot measurement method, the ICP monitoring method could be used in glaucoma patients in cases where ICP values are low than the normal range.
