Abstract

ABSTRACT Objective: The main aim of this study was to evaluate the performance of a platform designed for pediatricians to screen amblyopia using a smartphone. Methods: The medical records of consecutive children who received visual screening using a smartphone platform were retrospectively reviewed. The smartphone was used with a flash concentrator case and a software for capturing images of both eyes simultaneously by a photorefraction mechanism. The platform performance was compared to the comprehensive ophthalmological examination, which is considered the gold standard for detecting amblyopia. Sensitivity, specificity, positive predictive value, and negative predictive value of the software in detecting amblyopia risk factors were calculated. Results: A total of 157 children were included, with a mean age of 6.0±.5 years (range 5–7). In 94% of the cases, the software was able to analyze the images and release a result, determining whether or not the child presented with amblyopia risk factors. Compared to the ophthalmological examination, the smartphone platform sensitivity in detecting amblyopia risk factors was 84%, the specificity was 74%, the positive predictive value was 86%, and the negative predictive value was 70%. Conclusions: The sensitivity and specificity of the smartphone photoscreening platform to detect amblyopia risk factors were within the range of traditional instrument-based vision screening technology. A smartphone photorefraction platform appears to be a promising cost-effective alternative to assist pediatricians and minimize obstacles to vision screening and amblyopia detection. Future studies are needed to gather additional comparative data.

使用智能手机平台进行视力筛查

摘要目的：本研究的主要目的是评估儿科医生使用智能手机筛查弱视的平台的性能。方法：回顾性分析连续使用智能手机平台进行视觉筛查的儿童的医疗记录。该智能手机配备了一个闪光灯集中器外壳和一个通过光分解机制同时捕捉双眼图像的软件。该平台的性能与眼科综合检查进行了比较，后者被认为是检测弱视的黄金标准。计算软件检测弱视危险因素的敏感性、特异性、阳性预测值和阴性预测值。结果：共纳入157名儿童，平均年龄为6.0±.5岁（5-7岁）。在94%的病例中，该软件能够分析图像并发布结果，以确定儿童是否存在弱视风险因素。与眼科检查相比，智能手机平台检测弱视危险因素的敏感性为84%，特异性为74%，阳性预测值为86%，阴性预测值为70%。结论：智能手机光电筛查平台检测弱视危险因素的灵敏度和特异性在传统仪器视觉筛查技术的范围内。智能手机照片分割平台似乎是一种极具成本效益的替代方案，可以帮助儿科医生，最大限度地减少视力筛查和弱视检测的障碍。未来的研究需要收集更多的比较数据。
