Abstract

Purpose

To investigate the agreement between the ICare HOME tonometer and the Goldmann Applanation Tonometer (GAT) in assessing the peak intraocular pressure (IOP) during the water-drinking test (WDT).

Design

Prospective cross-sectional study.

Subjects

Seventy-nine eyes of 41 open-angle glaucoma patients were included in the study.

Methods

All of the included patients underwent a training session provided by ophthalmologist specialists to use the ICare HOME tonometer. Then the IOP was first measured with the GAT (AT900; Haag-Streit) by a trained physician, immediately followed by ICare HOME tonometer (TA022, ICare Oy) measurement by the patient. Four measurements were taken with each device with 15-minute differences as established by the WDT.

Main Outcome Measures

The agreement and degree of correlation of the peak IOP by both tonometers were assessed.

Results

The agreement between the ICare HOME and GAT was high during the WDT: the intraclass correlation coefficient (r) between the 2 methods from basal to 45 minutes: 0.94 (P < 0.001), at basal: 0.91 (P < 0.001), at 15 minutes: 0.94 (P < 0.001), at 30 minutes: 0.94 (P < 0.001), at 45 minutes: 0.95 (P < 0.001), and for peak IOP: 0.94 (P < 0.001). There was no significant difference between peak IOP with the GAT and ICare HOME (18.3 ± 4.6 [10–33] and 18.5 ± 5.0 [0–33], respectively, P = 0.533), nor between the delta of fluctuation between basal and peak IOP with the GAT and ICare HOME (3.96 ± 3.22 and 4.54 ± 3.92, P = 0.054).

Conclusions

Our study demonstrated a high agreement between the ICare HOME and the GAT during the WDT in a clinical environment with supervision.

Icare HOME眼压计与Goldmann眼压计在饮水试验中评估眼压峰值的一致性。

目的：探讨Icare家用眼压计与Goldmann眼压计（GAT）在饮水试验（WDT）中评估眼压峰值的一致性。设计:前瞻性横断面研究。研究对象：41例开角型青光眼患者79只眼。方法：所有纳入的患者都接受了由眼科专家提供的使用Icare®家用眼压仪的培训课程。然后用Goldmann眼压计(AT900；Haag-Streit;由训练有素的医生（Köniz, suia）进行测量，紧接着由患者进行Icare®家用血压仪（TA022, Icare Oy, Vanda, Finland）测量。根据WDT确定，每个装置进行了四次测量，相差15分钟。主要观察指标：评估两种眼压计测量的峰值眼压的一致性和相关程度。结果：在WDT期间，iCare与Goldmann压血压计之间的一致性很高：两种方法在基线至45 min之间的类内相关系数(r)为0.94 (p < 0.001)，在基线时为0.91 (p < 0.001)，在15 min时为0.94 (p < 0.001)，在30 min时为0.94 (p < 0.001)，在45 min时为0.95 (p < 0.001)，在IOP峰值时为0.94 （p < 0.001）。GAT和iCare的IOP峰值分别为18.3±4.6（10-33）和18.5±5.0(0-33)，差异无统计学意义（p = 0.533）； GAT和iCare的基础IOP与峰值的波动δ值分别为3.96±3.22和4.54±3.92，差异无统计学意义（p = 0.054）。结论：我们的研究表明，iCare HOME和Goldmann眼压计在临床环境监督下，在WDT期间具有很高的一致性。
