Abstract

BACKGROUND

The Spot Vision Screener has demonstrated good sensitivity and specificity in the pediatric ophthalmology clinic setting. We sought to evaluate the updated Spot (version 2.0.16) in a general pediatric population through a collaboration of the Storm Eye Institute of the Medical University of South Carolina, the Clinica Dr Clorito Picado, and National Children's Hospital of Costa Rica. We compared results of screening with the Spot and pediatric ophthalmologic examination and determined sensitivity and specificity of the Spot in detecting amblyogenic risk factors (ARFs) according to the 2013 AAPOS Vision Screening Committee guidelines for automated vision screeners.

METHODS

Children were screened with the Spot followed by a pediatric ophthalmologic examination. Cycloplegic refraction and motility findings were analyzed by age group to determine ARFs.

RESULTS

A total of 219 subjects, averaging 60 months of age (range, 20-119 mo) were included. The prevalence of ARFs in our population was 12.3% (27/219). The most common risk factor was astigmatism, with a prevalence of 8.7% (19/219). The Spot referred 43 children (19.6%). Sensitivity of the Spot was 92.6%; specificity, 90.6%. The positive predictive value was 58.1%; the negative predictive value, 98.9%.

CONCLUSIONS

The Spot demonstrated good sensitivity and specificity in detecting amblyopia risk factors in this general pediatric population.

摘要

背景

在儿科眼科诊所环境中，视力筛查仪已显示出良好的敏感性和特异性。我们试图通过南卡罗来纳医科大学的斯托姆眼科研究所、克洛里托·皮卡多诊所和哥斯达黎加国家儿童医院的合作，在普通儿科人群中评估更新后的视力筛查仪（2.0.16版本）。我们比较了视力筛查仪和儿科眼科检查的筛查结果，并根据2013年美国儿科学会眼科医师学会视力筛查委员会关于自动视力筛查仪的指南，确定了视力筛查仪在检测弱视危险因素（ARF）方面的敏感性和特异性。

方法

先用视力筛查仪对儿童进行筛查，然后进行儿科眼科检查。通过年龄组分析睫状肌麻痹验光和眼球运动结果，以确定弱视危险因素。

结果

共纳入219名受试者，平均年龄60个月（范围20 - 119个月）。我们研究人群中弱视危险因素的患病率为12.3%（27/219）。最常见的危险因素是散光，患病率为8.7%（19/219）。视力筛查仪转诊了43名儿童（19.6%）。视力筛查仪的敏感性为92.6%；特异性为90.6%。阳性预测值为58.1%；阴性预测值为98.9%。
