Abstract

PURPOSE

To evaluate the reliability and repeatability of intraocular pressure (IOP) measurements using a new rebound tonometer.

METHODS

Intraocular pressure was measured in 42 healthy human eyes of subjects aged 18-30 years (mean +/- standard deviation [SD] 21.5 +/- 3.2 years) using the ICare Rebound and Goldmann tonometers in two separate sessions.

RESULTS

Intraocular pressure measurements were found to read slightly, but not significantly, higher with the ICare tonometer compared with the Goldmann instrument in both sessions (first session: mean bias +/- SD + 0.50 +/- 2.33 mmHg; second session: mean bias +/- SD + 0.52 +/- 1.92 mmHg). Limits of agreement between repeated readings were +/- 5.11 mmHg for measurements taken with the ICare tonometer, compared with +/- 3.15 mmHg for measurements taken with the Goldmann method.

CONCLUSION

Measurement of IOP in normal, healthy subjects using the ICare rebound tonometer produced a small, statistically insignificant, positive bias when compared with the Goldmann tonometer. Intersessional repeatability of IOP taken with the ICare is poorer than that of IOP taken with the Goldmann tonometer, but is comparable with that of other non-Goldman-type tonometers currently available.

摘要

目的

使用一种新型回弹式眼压计评估眼压（IOP）测量的可靠性和可重复性。

方法

在两个不同的时间段，使用ICare回弹式眼压计和Goldmann眼压计对42只年龄在18至30岁（平均±标准差[SD]为21.5±3.2岁）的健康人眼进行眼压测量。

结果

在两个时间段中，与Goldmann眼压计相比，使用ICare眼压计测得的眼压读数略高，但差异不显著（第一个时间段：平均偏差±标准差为+0.50±2.33 mmHg；第二个时间段：平均偏差±标准差为+0.52±1.92 mmHg）。使用ICare眼压计进行的重复测量的一致性界限为±5.11 mmHg，而使用Goldmann方法进行的测量为±3.15 mmHg。
