Abstract

PURPOSE

To evaluate the accuracy of intraocular pressure (IOP) measurements obtained with the newly available iCare HOME (RTHOME) rebound tonometer compared with the iCare ONE (RTONE) tonometer and Goldmann applanation tonometry (GAT), and possible correlation with central corneal thickness (CCT).

MATERIALS AND METHODS

IOP measurements were obtained from 154 patients by an ophthalmologist (doc) using each of the above-mentioned tonometers. In addition, patients (pat) measured their own IOP with the RTHOME and RTONE. The means and SD of results obtained with the different tonometers were compared. Agreement between the tonometers was calculated using the Bland-Altman method.

RESULTS

Mean IOPs for the right eyes only were 15.9±6.4 mm Hg (RTONEdoc), 15.8±6.4 mm Hg (RTONEpat), 15.0±5.9 mm Hg (RTHOMEdoc), 14.9±6.3 mm Hg (RTHOMEpat), and 15.8±4.4 mm Hg (GAT). Bland-Altman analysis revealed mean differences (bias) between RTONEdoc and RTHOMEdoc, between RTHOMEdoc and RTHOMEpat, and between RTHOMEdoc and GAT of 0.8, 0.1, and -0.8 mm Hg, respectively, with 95% limits of agreement of -3.5 to 5.2, -4.9 to 5.1, and -7.2 to 5.6 mm Hg, respectively. Linear regression of the comparisons revealed a proportional error over the range of pressures examined in the case of RTHOMEdoc versus GAT (slope=0.32, P<0.001). Considering the data from all eyes, the difference between RTHOMEdoc and GAT correlated significantly with the CCT (P=0.01).

CONCLUSION

RTHOME readings correlate well with the GAT results although some limitations such as dependency of readings on CCT and increasing differences at lower and higher IOP levels need to be taken into account.

摘要

目的

评估新推出的iCare HOME（RTHOME）回弹式眼压计与iCare ONE（RTONE）眼压计及Goldmann压平眼压计（GAT）所测眼压（IOP）的准确性，以及与中央角膜厚度（CCT）的可能相关性。

材料与方法

一位眼科医生使用上述每种眼压计为154例患者测量眼压。此外，患者自己使用RTHOME和RTONE测量眼压。比较不同眼压计所测结果的均值和标准差。采用Bland-Altman方法计算眼压计之间的一致性。

结果

仅右眼的平均眼压分别为15.9±6.4 mmHg（RTONEdoc）、15.8±6.4 mmHg（RTONEpat）、15.0±5.9 mmHg（RTHOMEdoc）、14.9±6.3 mmHg（RTHOMEpat）和15.8±4.4 mmHg（GAT）。Bland-Altman分析显示，RTONEdoc与RTHOMEdoc之间、RTHOMEdoc与RTHOMEpat之间以及RTHOMEdoc与GAT之间的平均差异（偏差）分别为0.8、0.1和 -0.8 mmHg，95%一致性界限分别为 -3.5至5.2 mmHg、 -4.9至5.1 mmHg和 -7.2至5.6 mmHg。比较的线性回归显示，在RTHOMEdoc与GAT的情况下，在所检查的压力范围内存在比例误差（斜率 = 0.32，P<0.001）。考虑所有眼睛的数据，RTHOMEdoc与GAT之间的差异与CCT显著相关（P = 0.01）。
