To compare the refractive errors measured by the Spot photoscreener (with or without cycloplegia) to cycloplegic retinoscopy in 6- to 10-week-old infants.
101 right eyes from 101 healthy infants aged 6 to 10 weeks were recruited for this cross-sectional observational study. Refractive errors were measured using Spot photoscreener before and after cycloplegia, as well as cycloplegic retinoscopy. Comparisons between the refractive measurements were performed using one-way ANOVA with the post hoc Tukey HSD test or Kruskal-Wallis test with the Steel-Dwass test according to the data normality. Pearson's correlation test and 95% confidence intervals were calculated. The agreement was evaluated using a Bland-Altman plot with 95% limits of agreement of the differences.
Spot photoscreener was found to underestimate the spherical equivalent by 2.33 Diopters (D) in these infants. Following the induction of cycloplegia, the spherical equivalent measured by Spot photoscreener was in excellent agreement with cycloplegic retinoscopy with the mean difference of 0.01 D. Spot photoscreener overestimated cylindrical parameter by 0.2 D with poor agreement with cycloplegic retinoscopy no matter whether cycloplegia was induced. It had good agreement with cycloplegic retinoscopy in the vector than the vector measurement.
With the induction of cycloplegia, Spot photoscreener can accurately evaluate spherical equivalent in hyperopic infants with mild-to-moderate astigmatism. While it may provide valuable measurements of astigmatism, discrepancies in cylinder and axis should be taken into account.
比较在6至10周龄婴儿中，使用Spot视力筛查仪（散瞳或不散瞳）测量的屈光不正与散瞳检影验光结果。
本横断面观察性研究纳入了101名6至10周龄健康婴儿的101只右眼。在散瞳前后使用Spot视力筛查仪测量屈光不正，同时进行散瞳检影验光。根据数据正态性，使用单因素方差分析及事后Tukey HSD检验或Kruskal-Wallis检验及Steel-Dwass检验对屈光测量结果进行比较。计算Pearson相关检验和95%置信区间。使用Bland-Altman图评估差异的95%一致性界限来评估一致性。
发现Spot视力筛查仪在这些婴儿中低估等效球镜度2.33屈光度（D）。散瞳后，Spot视力筛查仪测量的等效球镜度与散瞳检影验光结果高度一致，平均差异为0.01 D。无论是否散瞳，Spot视力筛查仪高估柱镜参数0.2 D，与散瞳检影验光结果一致性较差。在矢量测量方面，它与散瞳检影验光结果一致性良好。
散瞳后，Spot视力筛查仪可准确评估轻度至中度散光远视婴儿的等效球镜度。虽然它可能提供有价值的散光测量结果，但应考虑柱镜和轴位的差异。
