Abstract:

There is a need to develop non-invasive methods to monitor the intracranial pressure ICP in space and on earth. In traumatic brain injury patients, elevated ICP is associated with pupils that are poorly reactive to light as measured by quantitative pupillometry. However, it is known whether pupillary reactivity will decreased when ICP is elevated but without brain injury or cerebral edema, such as in patients with idiopathic intracranial hypertension, or healthy subjects undergoing physiological maneuvers to transiently elevate the ICP. We sought to determine the pupillary reactivity related to maneuvers that elevate ICP including head down tilt, breath holding and Valsalva maneuver in healthy subject and patients with idiopathic intracranial hypertension.
