This study assesses the quality of retinal images captured using a non-mydriatic fundus camera within a teleophthalmologic platform in Taiwan. The objective was to evaluate the effectiveness of non-mydriatic fundus cameras for remote retinal screening and identify factors impacting image quality. From June 2020 to August 2022, 629 patients from five rural infirmaries underwent ophthalmic examinations, with fundus images captured without pupil dilation. These images were reviewed by senior ophthalmologists and graded based on quality. The results indicated that approximately 70% of images were of satisfactory diagnostic quality. Risk factors for poor image quality included older age, the presence of cataracts, pseudophakia, and diabetes mellitus. This study demonstrates the feasibility of using non-mydriatic fundus cameras for teleophthalmology, highlighting the importance of identifying and addressing factors that affect image quality to enhance diagnostic accuracy in remote settings.
本研究评估了在台湾的远程眼科平台上使用非散瞳眼底相机拍摄的视网膜图像质量。目的是评估非散瞳眼底相机用于远程视网膜筛查的有效性，并确定影响图像质量的因素。2020年6月至2022年8月，来自五个农村医务室的629名患者接受了眼科检查，在未散瞳的情况下拍摄了眼底图像。这些图像由资深眼科医生进行审查，并根据质量进行分级。结果表明，约70%的图像具有令人满意的诊断质量。图像质量差的风险因素包括年龄较大、存在白内障、人工晶状体眼和糖尿病。本研究证明了使用非散瞳眼底相机进行远程眼科检查的可行性，强调了识别和解决影响图像质量的因素以提高远程环境中诊断准确性的重要性。
