Seventy-five patients under 40 years of age with no history of ocular, cardiovascular, or cerebrovascular disease were examined with four commonly used ophthalmodynamometers. There was a significant difference in the absolute values measured with each instrument and the ophthalmic to brachial artery pressure ratio. The standard deviations were comparable between 8.1 and 10.2%. The absolute value of the average percent difference between the right and the left eye ranged from 3.6% with the Galin unit to 6.7% with the Sisler unit. Limits of +/- 15% for ophthalmic artery to brachial artery pressure ratio and 10% for right to left pressure difference should be used for 95% confidence levels. There was a small but definite correlation between the ocular coefficient of rigidity and pressure differences between direct and indirect instruments.
对75名年龄在40岁以下、无眼部、心血管或脑血管疾病史的患者，使用四种常用的眼压计进行了检查。每种仪器测量的绝对值以及眼动脉与肱动脉压力比存在显著差异。标准差在8.1%至10.2%之间具有可比性。右眼和左眼之间平均百分比差异的绝对值范围从Galin眼压计的3.6%到Sisler眼压计的6.7%。眼动脉与肱动脉压力比的±15%以及左右眼压力差的10%的限值应用于95%的置信水平。眼硬度系数与直接和间接仪器之间的压力差之间存在微小但确定的相关性。
