摘要
引言:本研究旨在比较光学低相干反射计(LenStar LS900)和前段光学相干断层扫描(CASIA2 OCT)之间的前段测量。方法:根据纳入和排除标准,198名健康参与者的198只右眼被用于本研究。使用LenStar LS 900和CASIA2 OCT测量角膜生物测量参数,如中央角膜厚度(CCT)、前房深度(ACD)、角膜曲率计和前房宽度(ACW)。评估这两种仪器之间的差异和相关性。协议计算为95%的协议限制(LoA)。结果:在198名平均年龄为29.39±7.88岁的受试者中,106人(53.5%)为女性。LenStar和OCT的平均CCT值分别为531.7±35.25和527.3±37.82µm(P 0.0001)。LenStar和OCT的ACD测量值分别为2.92±0.40和2.95±0.43 mm(P=0.0549,CCT、ACD、ACW和散光分别为-0.50至-0.43mm、-0.32至0.82mm和-0.70至0.87D。结论:LenStar和OCT具有可互换的ACD测量值;然而,用这两种仪器测量的CCT、ACW和角膜散光的结果显示出临床上的显著差异
Agreement of Ocular Biometry Measured by LenStar LS 900 and CASIA2 Optical Coherence Tomography
Introduction:The present study aimed to compare the anterior segment measurements between optical low-coherence reflectometry (LenStar LS900) and anterior segment optical coherence tomography (CASIA2 OCT). Methods:A total of 198 right eyes of 198 healthy participants were used for the current study, according to the inclusion and exclusion criteria. Ocular biometry parameters, such as central corneal thickness (CCT), anterior chamber depth (ACD), keratometry, and anterior chamber width (ACW), were measured usingLenStar LS 900 and CASIA2 OCT. The differences and correlations were assessed between these two instruments. The agreement was calculated as the 95% limits of agreement (LoA). Results: Among 198 subjects with a mean age of 29.39±7.88 years who enrolled in the study, 106 individuals (53.5%) were women. The mean CCT values were 531.7±35.25 and 527.3±37.82 µm for LenStar and OCT, respectively (P˂0.0001). The ACD measurements showed 2.92±0.40 and 2.95±0.43 mm for LenStar and OCT, respectively (P=0.0549). The ACW mean values were 12.04±0.52 and 11.79±0.49 mm by LenStar and OCT (P˂0.0001). The 95% LoA between the two instruments were within the ranges of -20.79 to 29.43 µm, -0.50 to -0.43 mm, -0.32 to 0.82 mm, and -0.70 to 0.87 D for CCT, ACD, ACW, and astigmatism, respectively. Conclusion: LenStar and OCT showed to have interchangeable ACD measurements; however, the results of CCT, ACW, and corneal astigmatism measured by these two instruments demonstrated clinically significant differences
