我们对高画质便携式非散瞳眼底相机进行了改进和重建，并将其与台式眼底相机进行了比较，以评估新相机对视网膜疾病的检测效果。我们设计并制作了一种新型的手持式眼底照相器，并带有远程医疗系统。通过拍摄254名患者的364只眼的照片，将眼底相机的图像质量与现有的商用桌面相机进行了比较。在由两种类型的相机拍摄的全部800张眼底图像中，每个相机400张图像用四种图像清晰度分类进行分级。使用便携式眼底照像机，总体质量优63%(252/400)，良20.5%(82/400)，可11.75%(47/400)，差4.75%(19/400)。台式眼底照相总体质量优70.75%(283/400)，良20.4%(51/400)，可13.25%(53/400)，差3.25%(13/400)。常见的视网膜疾病很容易从便携式眼底相机获得的眼底图像中识别出来。该新型非散瞳便携式眼底相机具有专业的眼底图像质量。革命性的筛查摄像头提供了一个基础平台，可以潜在地改善视网膜筛查计划的可及性。
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. 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. 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. 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.
