The spot vision screener (SVS) has been widely used for eye health examinations of infants and young children. The purpose of this study was to evaluate the reproducibility of two SVS measurements in children with ophthalmological diseases.
29 patients aged 15 years or younger who visited our hospital for refraction examinations with SVS before and at least 60 minutes after administration of 2 drops of 1% cyclopentolate ophthalmic solution (before and after cycloplegia) were included in this study. Two SVS measurements were made before and after cycloplegia, respectively. Intraclass correlation coefficients (ICCs) and Bland-Altman analysis for spherical, spherical equivalent (SE), cylindrical, J0, and J45 values before and after cycloplegia were analyzed.
The mean age ± standard deviation (SD) of the 29 patients was 7.6 ± 2.4 years. There were 11 males and 18 females. The mean spherical values based on the SVS before and after cycloplegia were 0.42 ± 1.67 diopter (D), and 1.47 ± 2.23 D for the first measurement and 0.60 ± 1.74 D, and 1.42 ± 2.27 D for the second measurement, respectively. The mean cylindrical values based on SVS before and after cycloplegia were -1.45 ± 0.96 D and -1.65 ± 0.89 D for the first measurement and -1.58 ± 1.13 D and -1.66 ± 0.91 D for the second measurement, respectively. The ICCs for the first and second spherical, SE, cylindrical, J0, and J45 values before cycloplegia were 0.95, 0.98, 0.83, 0.86, and 0.86, respectively. The ICCs for the first and second spherical, SE, cylindrical, J0, and J45 values after cycloplegia were 0.99, 0.99, 0,87, 0.73, and 0.80, respectively. The Bland-Altman analysis of the first and second spherical and SE values before cycloplegia showed fan-shaped variation as hyperopia increased.
Two consecutive SVS refraction measurements have a high degree of reproducibility for spherical and SE values but a low degree for cylindrical, J0, and J45 values. From these results, multiple measurements are required to obtain reliable results for cylindrical values.
点状视力筛查仪（SVS）已广泛用于婴幼儿的眼部健康检查。本研究的目的是评估在患有眼科疾病的儿童中两次SVS测量的可重复性。
本研究纳入了29例15岁及以下的患者，这些患者在我院使用SVS进行验光检查，在滴入2滴1%环喷托酯滴眼液之前（散瞳前）和至少60分钟后（散瞳后）分别进行了两次SVS测量。分别在散瞳前后进行两次SVS测量。分析了散瞳前后球镜、等效球镜（SE）、柱镜、J0和J45值的组内相关系数（ICC）和Bland-Altman分析。
29例患者的平均年龄±标准差（SD）为7.6±2.4岁。男性11例，女性18例。基于SVS的散瞳前和散瞳后第一次测量的平均球镜值分别为0.42±1.67屈光度（D）和1.47±2.23 D，第二次测量分别为0.60±1.74 D和1.42±2.27 D。基于SVS的散瞳前和散瞳后第一次测量的平均柱镜值分别为-1.45±0.96 D和-1.65±0.89 D，第二次测量分别为-1.58±1.13 D和-1.66±0.91 D。散瞳前第一次和第二次球镜、SE、柱镜、J0和J45值的ICC分别为0.95、0.98、0.83、0.86和0.86。散瞳后第一次和第二次球镜、SE、柱镜、J0和J45值的ICC分别为0.99、0.99、0.87、0.73和0.80。散瞳前第一次和第二次球镜及SE值的Bland-Altman分析显示，随着远视度数增加呈扇形变化。
连续两次SVS验光测量对于球镜和SE值具有高度可重复性，但对于柱镜、J0和J45值可重复性较低。根据这些结果，对于柱镜值需要进行多次测量以获得可靠结果。
