To assess the reliability and repeatability of periorbital biometric measurements using ImageJ software and to assess if the horizontal visible iris diameter (HVID) serves as a reliable scale for facial measurements.
This study was a prospective, single-blind, comparative study. Two clinicians performed 12 periorbital measurements on 100 standardised face photographs. Each individual's HVID was determined by Orbscan IIz and used as a scale for measurements using ImageJ software. All measurements were repeated using the 'average' HVID of the study population as a measurement scale. Intraclass correlation coefficient (ICC) and Pearson product-moment coefficient were used as statistical tests to analyse the data.
The range of ICC for intra- and interobserver variability was 0.79-0.99 and 0.86-0.99, respectively. Test-retest reliability ranged from 0.66-1.0 to 0.77-0.98, respectively. When average HVID of the study population was used as scale, ICC ranged from 0.83 to 0.99, and the test-retest reliability ranged from 0.83 to 0.96 and the measurements correlated well with recordings done with individual Orbscan HVID measurements.
Periorbital biometric measurements using ImageJ software are reproducible and repeatable. Average HVID of the population as measured by Orbscan is a reliable scale for facial measurements.
使用ImageJ软件评估眶周生物特征测量的可靠性和可重复性，并评估水平可见虹膜直径（HVID）是否可作为面部测量的可靠尺度。
本研究为前瞻性、单盲、对比研究。两名临床医生对100张标准化面部照片进行了12项眶周测量。通过Orbscan IIz确定每个人的HVID，并将其用作使用ImageJ软件进行测量的尺度。所有测量均以研究人群的“平均”HVID作为测量尺度重复进行。使用组内相关系数（ICC）和皮尔逊积矩系数作为统计检验来分析数据。
观察者内和观察者间变异性的ICC范围分别为0.79 - 0.99和0.86 - 0.99。重测信度分别为0.66 - 1.0至0.77 - 0.98。当以研究人群的平均HVID作为尺度时，ICC范围为0.83至0.99，重测信度范围为0.83至0.96，且测量结果与使用个体Orbscan HVID测量的记录相关性良好。
使用ImageJ软件进行眶周生物特征测量具有可重复性。通过Orbscan测量的人群平均HVID是面部测量的可靠尺度。
