A new digitalized differential pulse timing oculoplethysmograph was used to detect the presence or absence of significant carotid artery stenosis in 95 consecutive patients undergoing bilateral selective carotid arteriograms. The test had an over-all accuracy rate of 88 to 93 per cent. the unilateral or eye-to-eye time delay was the applicable criteria in 87 patients. If this time delay is seven milliseconds or less, there is a 95 per cent probability that the patient has normal carotid arteries. Time delays equal to, or greater than, eight milliseconds indicate a stenotic carotid artery, the most patients in this category have time delays of greater than 15 milliseconds, a highly specific finding with a 98 per cent or greater confidence in the interpretation of significant carotid artery stenosis.
一种新型数字化差分脉冲定时眼体积描记仪被用于对95例连续接受双侧选择性颈动脉造影的患者检测是否存在显著的颈动脉狭窄。该检测的总体准确率为88%至93%。单侧或两眼间的时间延迟是87例患者适用的标准。如果该时间延迟为7毫秒或更短，则患者有95%的概率颈动脉正常。时间延迟等于或大于8毫秒表明颈动脉狭窄，这类患者中大多数时间延迟大于15毫秒，这是一个高度特异的发现，对显著颈动脉狭窄的解读有98%或更高的置信度。
