Finite Element Modeling of Factors Influencing Optic Nerve Head Deformation Due to Intracranial Pressure

摘要

PURPOSE. Visual impairment and intracranial pressure (VIIP) syndrome is a health concern for long-duration spaceflight, and a proposed risk factor is elevation of intracranial pressure (ICP). Our goal was to use finite element modeling to simulate how elevated ICP and interindividual differences affect tissue deformation within the optic nerve head (ONH).
