Non-Invasive Intracranial Pressure Monitor

Currently the only way to measure cranial pressure is a spinal tap or surgery to measure the pressure. Spinal taps are done thousands times a year to measure intracranial pressure in people with head trauma, headaches or inflammatory disease. High pressure is treated with medications or surgery to prevent complications such as vision loss, headaches, nausea or even a stroke.

Being able to effectively measure intracranial pressure without an x-ray or spinal tap would save money and discomfort. Eye Technology Institute physicians have invented a device that calculates pressure intracranial pressure by scanning the optic nerve in back of the eye with optical coherence tomography. This involves modification of a device that is commonly available in ophthalmology offices. We are currently testing its accuracy.
