To determine the repeatability of refractive values measured using the Spot vision screener in healthy children and children with refractive errors. This cross-sectional study included 170 eyes of 85 healthy children (normal group), and 50 eyes of 25 children wearing spectacles for refractive errors (spectacles group). The spherical equivalent value, cylindrical value, and inter-ocular differences in the spherical equivalent values were analyzed. The repeatability of the refractive values measured using the Spot vision screener was determined using intra-class correlation coefficients (ICCs) and 95% limits of agreement. In the normal group, ICC values for the spherical equivalent value, cylindrical value, and amount of anisometropia were 0.77, 0.80, and 0.64, respectively. In the spectacles group with spectacles they were 0.89, 0.67, and 0.78, respectively. In the spectacles group without spectacles they were 0.96, 0.78, and 0.97, respectively. The 95% limits of agreement between consecutive measurements for the spherical equivalent value, cylindrical value, and amount of anisometropia were within ±1.00 D in the normal group and the spectacles group with spectacles, and over ±1.00 D in the spectacles group without spectacles. The Spot vision screener can ensure better than moderate repeatability with and without spectacles.
确定使用Spot视力筛查仪测量健康儿童和屈光不正儿童屈光值的可重复性。这项横断面研究纳入了85名健康儿童的170只眼（正常组），以及25名佩戴矫正屈光不正眼镜的儿童的50只眼（眼镜组）。分析了等效球镜值、柱镜值以及等效球镜值的双眼差值。使用组内相关系数（ICC）和95%一致性界限来确定使用Spot视力筛查仪测量的屈光值的可重复性。在正常组中，等效球镜值、柱镜值和屈光参差量的ICC值分别为0.77、0.80和0.64。在佩戴眼镜的眼镜组中，它们分别为0.89、0.67和0.78。在未佩戴眼镜的眼镜组中，它们分别为0.96、0.78和0.97。正常组和佩戴眼镜的眼镜组中，等效球镜值、柱镜值和屈光参差量连续测量的95%一致性界限在±1.00 D以内，而未佩戴眼镜的眼镜组中则超过±1.00 D。Spot视力筛查仪无论有无眼镜都能确保具有优于中等程度的可重复性。
