We retrospectively compared the central corneal thickness (CCT) obtained by ultrasound pachymetry (USP; SP-3000, Tomey Corp., Nagoya, Japan), non-contact tonopachy (TP) (NT-530P, Nidek Co., Ltd., Gamagori, Japan), Pentacam HR (OCULUS Inc., Wetzlar, Germany), and RTVue optical coherence tomography (OCT) (Optovue Inc., Fremont, CA, USA) in 78 eyes of 78 healthy subjects with myopia. Agreement between the measurement methods was evaluated using 95% confidence intervals for the limits of agreement (LoA). The mean CCT values were 546.9 ± 34.7, 548.1 ± 33.5, 559.2 ± 34.0, and 547.2 ± 34.8 μm for USP, non-contact TP, Pentacam, and RTVue, respectively. The thickest and the thinnest mean CCT values corresponded to those obtained by Pentacam HR and USP, respectively. Plots of the differences against the means showed the best agreement between USP and RTVue (LoA, 10.14-10.70 μm), while the largest discrepancy was observed between RTVue and Pentacam systems (LoA, -25.47-1.44 μm). Our data showed that CCT measurements using these 4 instruments were well correlated. However, the results from Pentacam differed significantly from those of the other instruments.
我们回顾性比较了超声角膜测厚仪（USP；SP-3000，Tomey 株式会社，名古屋，日本）、非接触眼压计（TP）（NT-530P，尼德克株式会社，滨松，日本）、Pentacam HR（OCULUS 公司，弗里蒙特，加利福尼亚，美国）和 RTVue 光学相干断层扫描仪（OCT）（Optovue 公司，弗里蒙特，加利福尼亚，美国）在 78 名近视健康受试者的 78 只眼中的中央角膜厚度（CCT）。使用 95%置信区间（LoA）评估测量方法之间的一致性。USP、非接触 TP、Pentacam 和 RTVue 的平均 CCT 值分别为 546.9±34.7μm、548.1±33.5μm、559.2±34.0μm 和 547.2±34.8μm。最厚和最薄的平均 CCT 值分别对应于 Pentacam HR 和 USP 获得的值。差异与平均值的图显示 USP 和 RTVue 之间的一致性最好（LoA，10.14-10.70μm），而 RTVue 和 Pentacam 系统之间的差异最大（LoA，-25.47-1.44μm）。我们的数据表明，这 4 种仪器的 CCT 测量值相关性良好。然而，Pentacam 的结果与其他仪器的结果有显著差异。
