摘要

目的:获得白内障治疗和诊断工具继续受到财政和后勤障碍的阻碍。因此,通过便携式设备进行基于摄影的白内障分析为偏远地区的白内障检测提供了一个有希望的解决方案。本研究分析了基于晶状体混浊分级III系统的便携式白内障诊断装置的准确性。方法:在弱光环境下拍摄眼球前段图像,利用红外摄影技术自动圈定瞳孔区域标记。使用卷积神经网络自动分析捕获的图像。研究组为白内障患者,对照组为非白内障患者。结果:共分析270只眼,其中白内障眼143只,对照眼127只。总共分析了599张照片。孤立性核性白内障是最常见的亚型(37.5%),其次是核性白内障合并皮质性白内障(30.3%)。准确度为88.5% (CI: 83.19% ~ 94.69%),特异性为84.62% (CI: 71.79% ~ 97.30%),阳性预测值为91.78% (CI: 74.36% ~ 97.30%),阴性预测值为82.50% (CI: 74.36% ~ 97.30%)。结论:该便携式设备是一种简便易用的白内障筛查技术,可在偏远地区解释结果。这一创新可以减少白内障致盲的发生,并防止早期白内障的过早手术干预。

Evaluation of the effectiveness of a portable device for diagnosing cataract.

Purpose: Access to cataract treatment and diagnostic tools continues to be hindered by financial and logistical barriers. Thus, photography-based cataract analysis via portable devices offers a promising solution for the detection of cataracts in remote regions. In this study, the accuracy of a portable device that is based on the Lens Opacities Classification III System for diagnosing cataracts was analyzed.

Methods: Photographs of the anterior segment of the eye were taken in a low-light environment, and the pupillary region markings were automatically delineated using infrared photography. The captured images were automatically analyzed using a convolutional neural network. The study group included patients with cataracts, and the control group included patients without cataracts.

Results: A total of 270 eyes were analyzed, which included 143 eyes with cataracts and 127 control eyes. A total of 599 photos were analyzed. The isolated nuclear cataract was the most frequently detected subtype (37.5%), followed by a nuclear cataract associated with a cortical cataract (30.3%). The device's accuracy was 88.5% (Confidence intervals (CI), 83.19%-94.69%), specificity was 84.62% (CI 71.79%-97.30%), positive predictive value was 91.78% (CI 74.36%-97.30%), and negative predictive value was 82.50% (CI 74.36%-97.30%).

Conclusion: The portable device is a simplified user-friendly cataract screening technique that can interpret results in remote regions. This innovation could mitigate the occurrence of cataract-induced blindness and prevent premature surgical interventions in early-stage cataracts.
