目的：评估 iCare 回弹眼压计与 Goldmann 压平眼压计 (GAT)、Tonopen XL 和非接触式眼压计测量眼内压 (IOP) 的一致性，以及中央角膜厚度 (CCT) 对这四种眼压计对 45 只眼睛（12 只对照眼和 33 只青光眼或高眼压眼）进行的 IOP 测量的影响。设计：临床相关实验研究。方法：通过 Bland-Altman 方法评估眼压计方法间一致性。通过线性回归分析 CCT 与绝对 IOP 值和眼压计差异的关系。 结果：iCare 与 GAT、Tonopen XL 和非接触式眼压计之间 IOP 读数的平均差异（95% 一致性限度）分别为 1.40 +/- 4.29、0.00 +/- 4.78 和 2.22 +/- 4.19 mm Hg。所有眼压测量均与 CCT 显着相关。随着 CCT 变厚，iCare 大大高估了 GAT 和 Tonopen XL。 结论：尽管受到 CCT 的影响，iCare 与压平眼压计非常吻合。
PURPOSE: To evaluate the agreement of iCare rebound tonometer in measuring intraocular pressure (IOP) with Goldmann applanation tonometer (GAT), Tonopen XL, and noncontact tonometer, and the influence of the central corneal thickness (CCT) on IOP measurements made with these four tonometers in 45 (12 control and 33 glaucomatous or ocular hypertensive) eyes.DESIGN: Clinically relevant experimental study.METHODS: Tonometer intermethod agreement was assessed by the Bland-Altman method. The relations of CCT with absolute IOP values and intertonometer differences were analyzed by linear regression.RESULTS: The mean differences (95% limits of agreement) in IOP readings between iCare and GAT, Tonopen XL, and noncontact tonometer were 1.40 +/- 4.29, 0.00 +/- 4.78, and 2.22 +/- 4.19 mm Hg, respectively. All tonometries had a marked association with CCT. As the CCT got thicker, iCare considerably overestimated GAT and Tonopen XL.CONCLUSIONS: Although influenced by CCT, iCare agrees well with applanation tonometers.
