Abstract

A feasibility study of a noninvasive intraocular tonometer consisting of a linear voltage differential transformer (LVDT) for measurement of intracranial pressure (ICP) is discussed. The feasibility was assessed by measuring ICP through an artificially created fontanel in pigs. An LVDT deflection corresponds directly with the response of an invasive pressure transducer inserted into the cerebrospinal fluid. The LVDT can also provide a discrete measurement of intracranial pressure. A handheld LVDT tonometer would allow for a quick noninvasive assessment of ICP, and serve as a screening process for infants at risk of abnormal ICP
