Ocular Rigidity, Ocular Pulse Amplitude, and Pulsatile Ocular Blood Flow: The Effect of Intraocular Pressure

Abstract

The present results suggest a nonlinear pressure-volume relation in the living human eye characterized by an increase in rigidity at higher IOP levels. The increased OPA and decreased pulse volume relate to the decreased POBF and the increased mechanical resistance of the ocular wall at high IOP levels.
