BACKGROUND:We modified and reconstructed a high image quality portable non-mydriatic fundus camera and compared it with the tabletop fundus camera to evaluate the efficacy of the new camera in detecting retinal diseases.
METHODS:We designed and built a novel portable handheld fundus camera with telemedicine system. The image quality of fundus cameras was compared to that of existing commercial tabletop cameras by taking photographs of 364 eyes from the 254 patients. In all 800 fundus images taken by two camera types, 400 images per camera, were graded with the four image clarity classifications.
RESULTS:Using the portable fundus camera, 63% (252/400) images were graded as excellent overall quality, 20.5% (82/400) were good, 11.75% (47/400) were fair, and 4.75% (19/400) were inadequate. Using the tabletop fundus camera, 70.75% (283/400) images were graded as excellent overall quality, 20.4% (51/400) were good, 13.25% (53/400) were fair, and 3.25% (13/400) were inadequate. Common retinal diseases were easily identified from fundus images obtained from the portable fundus camera.
CONCLUSION:The new type of non-mydriatic portable fundus camera was qualified to have professional quality of fundus images. The revolutionary screening camera provides a foundational platform which can potentially improve the accessibility of retinal screening programmes.

背景：我们修改并重建了高图像质量的便携式非散瞳眼底照相机，并将其与台式眼底照相机进行比较，以评估新照相机在检测视网膜疾病中的功效。
方法：我们设计并制造了一种新型的带有远程医疗系统的便携式手持眼底照相机。通过拍摄254名患者的364眼照片，将眼底照相机的图像质量与现有商用台式照相机的图像质量进行了比较。在两种相机类型拍摄的全部800张眼底图像中，每台相机400张图像被分为四个图像清晰度分类。
结果：使用便携式眼底照相机，将63％（252/400）的图像评为总体质量优良，20.5％（82/400）的图像质量良好，11.75％（47/400）的图像是良好的，以及4.75％（19/400）的图像）不足。使用台式眼底照相机，将70.75％（283/400）的图像评为总体质量优良，20.4％（51/400）的图像质量良好，13.25％（53/400）的图像质量良好，3.25％（13/400）的图像质量良好不足。从便携式眼底照相机获得的眼底图像很容易识别出常见的视网膜疾病。
结论：新型非散瞳便携式眼底照相机经鉴定具有专业的眼底图像质量。革命性的筛查摄像机提供了一个基础平台，可以潜在地改善视网膜筛查程序的可及性。
