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 (7.3 ± 4.3) and IOPcc (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.
目的
评估使用Corvis ST（CST）和眼反应分析仪（ORA）测量眼内压（IOP）的可重复性。
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。所有受试者均使用Goldmann压平眼压计、CST和ORA进行眼压评估。使用CST时，计算生物力学校正眼压（bIOP）；据称bIOP对生物力学特性的依赖性较小。对于ORA，得出角膜补偿眼压（IOPcc）和Goldmann相关眼压（IOPg）。使用变异系数（CV）和组内相关系数（ICC）评估各种眼压值的可重复性。
结果
bIOP的CV（5.5±3.1：平均值±标准差）明显小于IOPg（7.3±4.3）和IOPcc（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在眼压测量中显示出更好的准确性和可重复性。
翻译相关性
CST测量的bIOP比ORA测量的IOPcc具有更好的可重复性。
