评估儿科视力扫描仪 (PVS),这是一种手持式视力筛查设备,旨在测试一般儿科人群的弱视和斜视。在这项前瞻性研究中,训练有素的研究人员使用 PVS 对 300 名符合条件的 24-72 个月大且无已知眼部疾病的儿童进行了弱视和斜视筛查。一名儿科眼科医生在不了解 PVS 筛查结果的情况下进行了全面的眼科检查。 PVS 的敏感性和特异性以 95% 置信区间计算。根据金标准眼科检查,6 名儿童 (2%) 患有弱视和/或斜视。 PVS 检测到了所有 6 例病例,敏感率为 100%(95% CI,54%−100%)。 PVS 转介了另外 45 名眼科检查结果正常的儿童 (15%),特异性率为 85%(95% CI,80%−89%)。 PVS 的中位采集时间为 28 秒。 PVS 在非丰富儿童群体中以高灵敏度检测出弱视。该设备可以让患有弱视和/或斜视的儿童在 2 岁时就被转诊至眼科护理专家处。鉴于其采集时间短,PVS 可以在儿科诊所中实施,对工作流程的影响最小。
To assess the Pediatric Vision Scanner (PVS), a handheld vision screening device designed to test for amblyopia and strabismus, in a general pediatric population. In this prospective study, trained research staff screened 300 eligible children 24–72 months of age with no known eye conditions for amblyopia and strabismus using the PVS. A pediatric ophthalmologist masked to PVS screening results then performed a comprehensive eye examination. Sensitivity and specificity of the PVS was calculated with a 95% confidence interval. Based on the gold standard eye examination, 6 children (2%) had amblyopia and/or strabismus. The PVS detected all 6 cases, yielding a sensitivity rate of 100% (95% CI, 54%−100%). The PVS referred 45 additional children (15%) who had normal ophthalmic findings, yielding a specificity rate of 85% (95% CI, 80%−89%). The median acquisition time for the PVS was 28 seconds. The PVS detected amblyopia with high sensitivity in a nonenriched pediatric population. The device would allow children with amblyopia and/or strabismus to be referred to an eye care specialist as early as 2 years old. Given its short acquisition time, the PVS can be implemented in a pediatric clinic with minimal impact on workflow.
