摘要临床意义准确测量前房深度是非常重要的。尚无关于儿童旋转Scheimpflug成像（Pentacam HR）和biograph（Lenstar LS 900）之间一致性的报告。因此，本研究探讨了Pentacam和Biograph在测量儿童前房深度方面的一致性。本研究旨在确定Pentacam和Biograph在测量儿童前房深度方面的一致性。方法采用整群抽样的方法，选取伊朗沙赫鲁德市城乡学生作为研究对象。学生们被运送到考试地点接受成像和验光测试。然后进行Pentacam成像，并使用biograph测量生物特征成分。在本报告中，前房深度是根据角膜内皮计算的。结果在随机抽取的6624名大学生中，有5620人参加了调查。在应用排除标准后，4882只眼被纳入最终分析。Pentacam测量的平均前房深度（3.09 ± 0.26 mm）高于biograph测量的平均前房深度（3.04 ± 0.24 mm）（p < 0.001）。两种器械之间的95%一致性限（LOA）为-0.19至0.09 mm。随着老化，两种器械之间差异的变化减小，LOA变窄，器械的相关系数增加。近视患者组内相关系数最高（0.974）。远视患者的95% LOA为−0.20至0.12 mm，近视患者为−0.17至0.07 mm，正视患者为−0.19至0.09 mm。结论Pentacam和Biograph可以交替使用，测量儿童前房深度。
ABSTRACT Clinical relevance Accurate measurement of the anterior chamber depth is very important. There is no report regarding the agreement between rotating Scheimpflug imaging (Pentacam HR) and biograph (Lenstar LS 900) in children. This study therefore explores the agreement between Pentacam and Biograph in measuring anterior chamber depth in children. Background This study aims to determine the agreement between Pentacam and Biograph in measuring anterior chamber depth in children. Methods The participants were students living in urban and rural areas of Shahroud, Iran, selected through cluster sampling. The students were transported to the examination site to undergo imaging and optometric tests. Pentacam imaging was then conducted, and biograph was used to measure biometric components. In this report, the anterior chamber depth was calculated from the corneal endothelium. Results Of 6624 students selected randomly, 5620 participated in the study. After applying the exclusion criteria, 4882 eyes were included in the final analysis. The mean anterior chamber depth measured by the Pentacam (3.09 ± 0.26 mm) was higher than that of biograph (3.04 ± 0.24 mm) (p < 0.001). The 95% limit of agreement (LOA) between the two devices was −0.19 to 0.09 mm. The variation of the difference between the two devices decreased, LOA became narrower, and the correlation coefficient of the devices increased with ageing. The highest intraclass correlation coefficient was seen among myopic (0.974) participants. The 95% LOA was −0.20 to 0.12 mm in hyperopic, −0.17 to 0.07 mm in myopic and −0.19 to 0.09 mm in emmetropic participants. Conclusion The Pentacam and Biograph can be used interchangeably for measuring the anterior chamber depth in children.
