Abstract

Purpose. To compare the refractive errors measured by the Spot photoscreener (with or without cycloplegia) to cycloplegic retinoscopy in 6- to 10-week-old infants. Materials and Methods. 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. Results. 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. Conclusions. 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.

中国 6 至 10 周婴儿的光斑照度计性能:横断面研究
目的在 6 到 10 周大的婴儿中,比较用 Spot 光筛仪(带或不带环形屈光镜)和环形屈光镜视网膜镜测得的屈光不正。材料和方法。这项横断面观察研究招募了 101 名 6 至 10 周大健康婴儿的 101 只右眼。在环形屈光手术前后使用点光筛查仪测量屈光不正,并进行环形屈光视网膜镜检查。根据数据的正态性,采用单因素方差分析和事后Tukey HSD检验或Kruskal-Wallis检验和Steel-Dwass检验对屈光测量结果进行比较。计算了皮尔逊相关性检验和 95% 的置信区间。使用布兰德-阿尔特曼图对差异的 95% 一致度进行评估。结果。发现点光筛查仪将这些婴儿的球面等效度数低估了 2.33 屈光度 (D)。在诱导环形角膜塑形术后,点阵光度计测量的球面等效度数与环形角膜塑形术视网膜镜测得的球面等效度数非常一致,平均相差 0.01 D。无论是否诱导了屈光不正,点阵光度计都会高估圆柱参数 0.2 D,与屈光视网膜镜的一致性较差。在矢量测量中,它与环形视网膜镜的一致性要好于矢量测量。结论。在诱导屈光不正的情况下,点光筛可以准确评估轻度至中度散光的远视婴儿的球面等值。虽然它可以提供有价值的散光测量值,但应考虑到柱面和轴线的差异。
