Abstract :
An innovative non-invasive absolute intracranial pressure (aICP) measurement method has been validated by multicenter comparative clinical studies. The method is based on two-depth transcranial Doppler technology and employs intracranial and extra cranial segments of the ophthalmic artery as a pressure sensor. The ophthalmic artery is used as a natural pair of scales which compares aICP with controlled pressure aPe which is externally applied to the orbit. In the case of scales balance, aICP=aPe. A two-depth transcranial Doppler device is used as a pressure balance indicator. The proposed method is the only non-invasive aICP measurement method which does not need patient-specific calibration.
