Abstract

Objectives: To compare the agreement and reliability values between an optical biometry based on swept-source optical coherence tomography (OCT) (IOLMaster 700; Carl Zeiss, Germany) and an ocular ultrasound-based biometry device (Nidek; US-4000 Echoscan, Japan) for axial length (AL), anterior chamber depth (ACD), and lens thickness (LT) measurements.

Methods: In this cross-sectional study, 101 eyes of 101 consecutive patients with mature cataract underwent routine eye examinations. Then, ocular biometry measurements through optical biometry and contact ultrasound biometry were carried out. The intraclass correlation coefficient (ICC) for reliability and Bland–Altman plots for the agreement between the mean findings of the two devices were analyzed.

Results: The mean age of patients was 61.6 ± 13.1 (range, 27–94) years. For AL, the mean differences were small (0.10 mm), but with a very strong correlation and excellent agreement (r = 0.999, ICC = 0.999, p < 0.001) between the two devices. Similarly, for ACD, the correlation was very high with excellent reliability (r = 0.958, ICC = 0.974, p < 0.001), though the ultrasound biometer reported a slightly deeper mean ACD (by 0.13 mm). For LT, the agreement and correlation were lower (r = 0.508, ICC = 0.663, p < 0.001), with the optical biometer reporting a thicker mean LT (0.31 mm) than the ultrasound biometer.

Conclusion: AL and ACD measurements from the optical biometry based on swept-source OCT and ultrasound can be used interchangeably in patients with mature cataract. However, LT measurements from the two devices should not be considered interchangeable.

基于扫描源光学相干层析成像与超声生物测量装置的光学生物测量在成熟白内障患者中的比较

目的：比较扫描源光学相干层析成像（OCT） (IOLMaster 700；卡尔蔡司，德国)和一种基于眼部超声的生物测量装置(Nidek；US-4000 Echoscan，日本)用于轴长（AL）、前房深度（ACD）和晶状体厚度（LT）测量。方法：对连续101例成熟白内障患者的101只眼进行常规眼科检查。然后，通过光学生物测量和接触超声生物测量进行眼部生物测量。分析了可靠性的类内相关系数（ICC）和两个设备的平均结果之间的一致性的Bland-Altman图。结果：患者平均年龄为61.6±13.1岁（范围27 ~ 94岁）。AL的平均差异很小（0.10 mm），但相关性很强，一致性很好(r = 0.999, ICC = 0.999, p <；0.001)。同样，对于ACD，相关性非常高，具有极好的信度(r = 0.958, ICC = 0.974, p <；0.001)，尽管超声生物计报告的平均ACD略深（0.13 mm）。对于LT，一致性和相关性较低(r = 0.508, ICC = 0.663, p <；0.001)，光学生物计报告的平均LT （0.31 mm）比超声生物计厚。结论：基于扫描源OCT和超声的光学生物测量可在成熟型白内障患者中交替使用AL和ACD。然而，从两个设备测量的LT不应该被认为是可互换的。

期刊介绍： IJCP is a general medical journal. IJCP gives special priority to work that has international appeal. IJCP publishes: Editorials. IJCP Editorials are commissioned. [Peer reviewed at the editor''s discretion] Perspectives. Most IJCP Perspectives are commissioned. Example. [Peer reviewed at the editor''s discretion] Study design and interpretation. Example. [Always peer reviewed] Original data from clinical investigations. In particular: Primary research papers from RCTs, observational studies, epidemiological studies; pre-specified sub-analyses; pooled analyses. [Always peer reviewed] Meta-analyses. [Always peer reviewed] Systematic reviews. From October 2009, special priority will be given to systematic reviews. [Always peer reviewed] Non-systematic/narrative reviews. From October 2009, reviews that are not systematic will be considered only if they include a discrete Methods section that must explicitly describe the authors'' approach. Special priority will, however, be given to systematic reviews. [Always peer reviewed] ''How to…'' papers. Example. [Always peer reviewed] Consensus statements. [Always peer reviewed] Short reports. [Always peer reviewed] Letters. [Peer reviewed at the editor''s discretion] International scope IJCP publishes work from investigators globally. Around 30% of IJCP articles list an author from the UK. Around 30% of IJCP articles list an author from the USA or Canada. Around 45% of IJCP articles list an author from a European country that is not the UK. Around 15% of articles published in IJCP list an author from a country in the Asia-Pacific region.
