Abstract

The Pulsair 2000 non-contact tonometer (Keeler Ltd, UK) is compared with the Goldmann applanation tonometer. Data from 80 eyes were acquired by four experienced observers. A linear regression analysis showed the relationship between the instruments to be: Pulsair = 0.66 + 0.95 Goldmann. Individual components of variation were analysed by analysis of variance which indicated a significant variation in the slope of the regression equation due to observers (p = 0.02) but not to the order in which topical anaesthesia was administered. Differences between two Pulsair instruments were of marginal significance (p = 0.07). The intercept of the regression equation was unaffected by any of the components of variation. Seventy-nine per cent of averaged intraocular pressure measurements obtained with the Pulsair 2000 fell on or within +/- 3 mmHg of those measured with the Goldmann tonometer. It is concluded that the Pulsair 2000 can provide clinically useful measurements of intraocular pressure.

摘要

将Pulsair 2000非接触眼压计（英国Keeler有限公司）与Goldmann压平眼压计进行比较。由四名经验丰富的观察者采集了80只眼睛的数据。线性回归分析表明，两种仪器之间的关系为：Pulsair = 0.66 + 0.95 Goldmann。通过方差分析对个体变异成分进行了分析，结果表明回归方程斜率因观察者而异（p = 0.02），但不因局部麻醉给药顺序而异。两台Pulsair眼压计之间的差异具有边缘显著性（p = 0.07）。回归方程的截距不受任何变异成分的影响。使用Pulsair 2000获得的平均眼压测量值中有79%落在Goldmann眼压计测量值的±3 mmHg范围内或与之相符。结论是，Pulsair 2000能够提供临床上有用的眼压测量值。
