Non-Invasive Measurement of Intracranial Pressure Through Application of Venous Ophthalmodynamometry

Non-Invasive Intracranial Pressure Monitoring

“…This method may help to improve current measurement methods [ 177 ]. An automatized approach achieved an accuracy of 77% in the estimation of the ICP [ 178 ].…”

Noninvasive methods to monitor intracranial pressure

“…Venous ophthalmodynamometry (ODM) measures central retinal vein (CRV) pressure by determining the force necessary to collapse the CRV; the force necessary to collapse the CRV is equal to the sum of the intraocular pressure (IOP) and a variable force applied externally to the globe [112,113]. Since the CRV is exposed to and influenced by ICP as it leaves the globe and travels within the substance of the optic nerve, CRV pressure is believed to be a useful biomarker for ICP [112]. Although this theory was first proposed in 1925 [114], it was not formally studied until 2000, when Firsching et al [115] showed a good correlation between ODM and invasively obtained ICP measurements.…”
