目的：评估用 Corvis ST (CST) 和眼反应分析仪 (ORA) 测量的眼压 (IOP) 的重复性。方法：对 141 名受试者的 141 只眼睛进行了研究，其中包括 35 只健康眼睛和 106 只青光眼眼睛。所有受试者均接受了 Goldmann 压平眼压计、CST 和 ORA 的眼压评估。通过 CST，计算生物力学校正 IOP (bIOP)；据称，bIOP 对生物力学特性的依赖性较小。对于 ORA，导出了角膜补偿眼压 (IOPcc) 和 Goldmann 相关 IOP (IOPg)。使用方差系数 (CV) 和组内相关系数 (ICC) 评估各种 IOP 值的重复性。结果：bIOP 的 CV（5.5 +/- 3.1：平均值 +/- 标准差）显着小于 IOPg（73 +/- 43）和 10Pcc（7.2 +/- 4.4）测量的 CV。 IOPg、IOPcc 和 bIOP 的 ICC 值分别为 0.90、0.80 和 0.86。结论：bIOP 对 IOP 测量显示出更好的预测性和可重复性。翻译相关性：CST 的 bIOP 测量比 ORA 的 IOPcc 测量具有更好的可重复性。
Purpose: To assess the repeatability of intraocular pressure (IOP) measured with the Corvis ST (CST) and the Ocular Response Analyzer (ORA).Methods: A total of 141 eyes from 141 subjects were studied, including 35 healthy eyes and 106 glaucomatous eyes. All subjects underwent IOP evaluations with Goldmann applanation tonometer, CST, and ORA. With CST, biomechanical corrected IOP (bIOP) was calculated; bIOP is purported to be less dependent on biomechanical properties. For ORA, corneal-compensated intraocular pressure (IOPcc) and Goldmann-correlated IOP (IOPg) were derived. The repeatability of the various IOP values was assessed using the coefficient of variance (CV) and the intraclass correlation coefficient (ICC).Results: The CV with bIOP (5.5 +/- 3.1: mean +/- standard deviation) was significantly smaller than the CVs measured with IOPg (73 +/- 43) and 10Pcc (7.2 +/- 4.4). ICC values were 0.90, 0.80, and 0.86 with IOPg, IOPcc, and bIOP, respectively.Conclusions: The bIOP showed a better prevision and repeatability for IOP measurement.Translational Relevance: The bIOP measurement from CST had a better reproducible than IOPcc measurement from ORA.
