Abstract
An intracranial pressure (ICP) within a patient's skull can be determined by observing a vessel in the patient's eye, desirably in the red and/or infrared (IR) spectrum, while causing the pressure inside the eye to increase. On or about the time the observed vessel collapses in response to increasing the pressure inside the eye, the pressure inside the eye is determined. The ICP can then be determined as a function of the pressure inside the eye. Desirably, the vessel being observed is the central retinal vein of the eye.
