To compare an optical coherence tomography (OCT) real-world reference database (RW-RDB) of "healthy" eyes obtained from optometry practices to a commercial reference database (RDB).
OCT scans from 6804 individuals 18 years and older were sampled from a larger database tested at 10 optometry practices involved in refractive and screening services. Employing a reading center method, OCT scans from both eyes of 4932 (4.9K) individuals were judged to be of acceptable quality with an absence of pathology. The 4.9K RW-RDB was compared to a commercial RDB with 398 eyes (398 RDB).
The means and distributions of global circumpapillary retinal nerve fiber layer (G-cpRNFL) and global ganglion cell layer (G-GCL) thickness, as well as five key anatomical parameters affecting cpRNFL thickness, were not significantly different for all but one parameter (fovea-to-disc distance) and one thickness metric (G-cpRNFL). In both cases, the difference amounted to less than 1.5%. By design, the number of 4.9K RW-RDB eyes 70 years and older (724, 14.7%) was greater than for the 398 RDB (40, 10.1%). The error bands on the 5% and 1% quantile regression lines (QRLs) were substantially narrower for the 4.9K RW-RDB.
The 398 RDB and 4.9K RW-RDB have similar characteristics and appear to come from a similar population. However, the large size of the 4.9K RW-RDB leads to narrower error bands of the QRLs, which has the potential to increase accuracy.
The larger RW-RDB offers the opportunity to better characterize healthy eyes for clinical diagnosis and clinical trials by furthering our understanding of the patterns of artifacts, exploring covariates, developing separate RW-RDBs, and/or improving AI models.
比较从参与屈光和筛查服务的 10 家验光机构的大型数据库中抽取的光学相干断层扫描(OCT)真实世界参考数据库(RW-RDB)与商业参考数据库(RDB)。
从参与屈光和筛查服务的 10 家验光机构的大型数据库中抽取了 6804 名 18 岁及以上个体的 OCT 扫描。采用阅读中心方法,对 4932 名(4.9K)个体的双眼 OCT 扫描进行了评估,认为这些扫描具有可接受的质量且不存在病变。将 4.9K RW-RDB 与 398 只眼睛的商业 RDB(398 RDB)进行了比较。
除了一个参数(视盘到黄斑中心凹的距离)和一个厚度指标(G-cpRNFL)外,所有参数的 G 环周视网膜神经纤维层(G-cpRNFL)和 G 节细胞层(G-GCL)的平均值和分布,以及影响 cpRNFL 厚度的五个关键解剖参数均无显著差异,且差异均小于 1.5%。由于设计原因,70 岁及以上的 4.9K RW-RDB 眼(724 只,占 14.7%)数量多于 398 RDB(40 只,占 10.1%)。5%和 1%分位数回归线(QRL)的误差带对于 4.9K RW-RDB 要窄得多。
398 RDB 和 4.9K RW-RDB 具有相似的特征,似乎来自相似的人群。然而,由于 4.9K RW-RDB 较大,QRL 的误差带更窄,这有可能提高准确性。
