Method of estimating ocular perfusion pressure

摘要

A method of estimating mean central retinal artery pressure (MCRAP) by using a microprocessor controlled tonometer (10), the method comprising;
using the tonometer (10) to determine a mean intraocular pressure [MIOP] including a diastolic value and a systolic value having an ocular pulse amplitude [OPA]
using the microprocessor (20) to calculate a ratio between OPA and MIOP;
using the microprocessor (20) to derive a multiplier from the ratio; and
using the microprocessor (20) to multiply MIOP by the derived multiplier to produce an estimate ofmean central artery pressure [MCRAP].
