To assess the reliability of measurements of intraocular pressure (i.o.p.), pulse amplitude (PA), and pulsatile ocular blood flow (POBF) and the validity of measurements of IOP with a new ocular blood flow tonograph.
Intraocular pressure pulse was assessed with pneumatic tonometry. In this study, we used the OBF Labs ocular blood flow tonograph with two different pneumatic probes, a modified Langham probe and a newly developed probe. One ophthalmologist compared two machines, first with the modified Langham probe and secondly with the newly developed probe (40 volunteers). Additionally, two ophthalmologists performed measurements on different days and in different sequence (34 volunteers). Furthermore, results of IOP measurements performed with this tonograph were compared to those of Goldmann applanation tonometry (213 volunteers).
Using the modified Langham probe, POBF and PA were associated with the machine used for the test. However, using the newly developed pobe, no relevant or statistically significant differences were found for any variables, and reliability coefficients were between 0.70 and 0.90. Linear regression analysis of the Goldmann applanation tonometer on the measurements of IOP with the tonograph showed a regression coefficient of 0.765.
Results of measurements performed with this ocular blood flow tonograph and the newly developed probe are expected to be reliable and comparable.
评估眼压（IOP）、脉搏振幅（PA）和搏动性眼血流量（POBF）测量的可靠性，以及一种新型眼血流眼压计测量眼压的有效性。
使用气动眼压计评估眼压脉冲。在本研究中，我们使用了OBF Labs眼血流眼压计和两种不同的气动探头，一种改良的兰厄姆探头和一种新开发的探头。一位眼科医生比较了两台机器，首先使用改良的兰厄姆探头，其次使用新开发的探头（40名志愿者）。此外，两位眼科医生在不同日期和不同顺序下进行测量（34名志愿者）。此外，将使用该眼压计进行的眼压测量结果与戈德曼压平眼压计的测量结果进行比较（213名志愿者）。
使用改良的兰厄姆探头时，POBF和PA与用于测试的机器有关。然而，使用新开发的探头时，未发现任何变量有相关或统计学上的显著差异，可靠性系数在0.70至0.90之间。戈德曼压平眼压计对眼压计测量的眼压进行线性回归分析，显示回归系数为0.765。
预计使用这种眼血流眼压计和新开发的探头进行测量的结果是可靠且可比的。
