The goal of this paper was to compare the intraocular pressure (IOP) measurements obtained via iCare Pro rebound (IRT), non-contact tonometry (NCT), and Goldmann applanation (GAT) tonometry in healthy subjects.
One hundred and twenty-five healthy individuals were included in this study. The participants' IOP measurements were obtained via non-contact tonometry. After routine ophthalmic examination, central corneal thickness (CCT) was measured with a topography device. Intraocular pressure was measured via iCare Pro rebound tonometry. After waiting for 5minutes, three measurements were taken with GAT under topical anaesthesia, and their means were recorded. Interdevice agreement was evaluated with the intraclass correlation coefficient (ICC) and Bland-Altman analysis.
The mean IOP measurements for NCT, IRT, and GAT were 15.97±2.99, 17.47±2.86, and 16.46±2.68mmHg, respectively. The mean difference between NCT and GAT was -0.49± 1.89mmHg, the mean difference between IRT and GAT was 1.01±1.90mmHg, and the mean difference between NCT and IRT was -1.50±2.02mmHg. Agreement between devices was found to be >0.8 for each tonometry ICC. There were significant positive correlations between the measurements obtained via these three instruments and CCT.
In this study, IOP was measured slightly lower with NCT than GAT, but it was about 1mmHg higher with IRT than GAT on average. All three devices appeared to be affected by CCT, with NCT being the most affected in this regard. The three instruments can be used for routine inspection and screening. However, considering the differences in the measurements obtained by using them, it is clear that following up IOP measurements with GAT measurements is beneficial in advanced glaucoma patients.
本文旨在比较健康受试者的 iCare Pro 回弹眼压（IRT）、非接触眼压计（NCT）和 Goldmann 压平眼压计（GAT）的眼压测量值。
本研究纳入 125 名健康个体。参与者的眼压通过非接触眼压计进行测量。在常规眼科检查后，使用地形图仪测量中央角膜厚度（CCT）。使用 iCare Pro 回弹眼压计测量眼内压。在等待 5 分钟后，在局部麻醉下用 GAT 进行三次测量，并记录其平均值。采用组内相关系数（ICC）和 Bland-Altman 分析评估设备间的一致性。
NCT、IRT 和 GAT 的平均眼压测量值分别为 15.97±2.99mmHg、17.47±2.86mmHg 和 16.46±2.68mmHg。NCT 和 GAT 之间的平均差值为-0.49±1.89mmHg，IRT 和 GAT 之间的平均差值为 1.01±1.90mmHg，NCT 和 IRT 之间的平均差值为-1.50±2.02mmHg。每种眼压计的 ICC 均>0.8，表明设备间具有高度一致性。这三种仪器的测量值与 CCT 之间均存在显著正相关。
在本研究中，与 GAT 相比，NCT 测量的眼压略低，但与 GAT 相比，IRT 平均高出约 1mmHg。这三种设备似乎都受到 CCT 的影响，其中 NCT 的影响最大。这三种仪器可用于常规检查和筛查。然而，考虑到使用它们获得的测量值存在差异，在高级青光眼患者中，使用 GAT 测量眼压进行随访显然是有益的。
