To assess the precision and reliability of a novel computerized heterophoria test (CHT).
One hundred and three subjects aged 20 to 48 (27.37 ± 5.15) were recruited from Wenzhou Medical University. All subjects with corrected spectacles were examined with CHT and a prism-neutralized objective cover test (POCT) in a randomized order. They were then re-examined with CHT within 1 week. Their heterophoria was measured at three different distances (3 m, 0.77 m and 0.4 m); the average was recorded after three consecutive measurements. Inter-examiner repeatability, intra-examiner repeatability of CHT and agreement between CHT and POCT were evaluated.
There was no significant difference among repeated measurements using CHT (all > 0.05). The difference between POCT and CHT was statistically significant at three distances (all < 0.001). However, the mean absolute difference was 1.20, 1.93, and 2.41, all of which were significantly smaller than the permissible range of error (4) at three different distances (all < 0.001).
The CHT demonstrated excellent inter- and intra-examiner repeatability, as well as good correlation with POCT. The differences between CHT and POCT were within the permissible range of error, indicating that CHT could provide a precise and reliable measurement for clinical applications.
评估一种新型电脑化隐斜视测试（CHT）的精度和可靠性。
从温州医科大学招募了103名年龄在20至48岁（27.37±5.15）之间的受试者。所有佩戴矫正眼镜的受试者均以随机顺序接受CHT和棱镜中和客观遮盖试验（POCT）检查。然后在1周内对他们进行CHT复查。在三个不同距离（3米、0.77米和0.4米）测量他们的隐斜视；连续测量三次后记录平均值。评估了CHT的检查者间重复性、检查者内重复性以及CHT与POCT之间的一致性。
使用CHT进行的重复测量之间无显著差异（均>0.05）。POCT与CHT在三个距离处的差异具有统计学意义（均<0.001）。然而，平均绝对差异分别为1.20、1.93和2.41，在三个不同距离处均显著小于允许误差范围（4）（均<0.001）。
CHT表现出出色的检查者间和检查者内重复性，以及与POCT的良好相关性。CHT与POCT之间的差异在允许误差范围内，表明CHT可为临床应用提供精确可靠的数据。
