目的：比较Pentacam三维眼前节分析仪与iTrace视觉分析仪在暗室环境中检测近视眼Kappa角的一致性。方法：采用回顾性研究，对近视门诊的86例志愿者共172眼使用iTrace视觉分析仪和Pentacam三维眼前节分析仪，分别测量其Kappa角，收集所测数据采用SPSS软件进行一致性分析。结果：Pentacam三维眼前节分析仪与iTrace视觉分析仪的Kappa角测量结果中，横坐标X值、纵坐标Y值和方位角度值比较差异有统计学意义(P<0.05)；弦距离值比较差异无统计学意义(P>0.05)。结论：Pentacam三维眼前节分析仪与iTrace视觉分析仪在近视患者Kappa角测量结果一致性存在差异，临床上应谨慎替换使用。

Objective: To compare the consistency of Pentacamand iTrace in detecting anglekappa. Methods: A retrospective study was carried out on a total of 172 eyes of 86 volunteers to measure the anglekappa by iTrace visual analyzer and  Pentacamanterior section analyzer in Zhengzhou Aier Eye Hospital. The measured data were collected and analyzed by SPSS software. Results: In the measurement results between Pentacam and iTrace , there was a statistically significant difference in the X value, Y value, and azimuth angle values of the horizontal axis (P<0.05); There was no statistically significant difference in chord distance values (P>0.05). Conclusions: 3-D anterior section analyzer the significant difference is found in the concordance of the anglekappa measurement results between the Pentacam and iTrace. It should be caution to replace two kinds of equipment in clinical practice.
