目标。这项研究比较了IOLMaster(蔡司，德国奥伯科兴)轴径测量和常规超声在儿童中的可重复性。方法：研究方法。对179名中国儿童(平均年龄10.6+/-0.8岁)进行了IOLMaster(部分相干干涉法，光学测厚仪)和Echoscan(US 800，日本东京，东京)的超声测量，其中37人重复测量近视发展。结果。IOL主轴长度测量的重复性好于Echoscan轴长测量(重复性95%的一致性限-0.047至0.038 mm)。IOL MASTER前房深度测量的重复性也比Echoscan前房深度测量(95%重复性范围-0.053~0.073 mm)要好。IOLMaster测量的眼轴长度(增加0.14 mm)和前房深度(增加0.09 mm)平均略大于Echoscan测量。结论。部分相干干涉技术，例如IOLMaster使用的技术，应该被认为是儿童轴长测量的标准技术，因为它们是非侵入性的，高精度，并且易于使用。
Aims. This study compares the repeatability of IOLMaster (Zeiss, Oberkochen, Germany) axial dimension measurements and conventional ultrasonography in children. Methods. A series of IOLMaster (partial coherence interferometry, optical pachometry) and Echoscan (US 800, Nidek, Tokyo, Japan) (ultrasound) measurements were taken on 179 Chinese children (mean age, 10.6 +/- 0.8 years) taking part in a longitudinal study of myopia development, and the measurements were repeated on 37 of these subjects. Results. IOLMaster axial length measurements showed better repeatability (95% limits of agreement for repeatability, -0.047 to 0.038 mm) than Echoscan axial length measurements (95% limits of agreement for repeatability, -0.85 to 0.67 mm). IOLMaster anterior chamber depth measurements also showed better repeatability (95% limits of agreement for repeatability, -0.053 to 0.073 mm) than Echoscan anterior chamber depth measurements (95% limits of agreement for repeatability, -0.57 to 0.49 mm). IOLMaster measurements were, on average, slightly larger than Echoscan measurements for axial length (by 0.14 mm) and anterior chamber depth (0.09 mm). Conclusion. Partial coherence interferometry techniques, such as that used by IOLMaster, should be considered as the standard technique for axial length measurement in children because they are noninvasive, highly precise, and easy to use.
