糖尿病性视网膜病变（diabetic retinopathy，DR）是导致全球成年人视觉障碍的主要原因之一。超广角眼底成像是近年来新发展的眼底成像技术，可以捕获约80%的视网膜面积，具有视野广、操作简易快捷、免散瞳、分辨率高等优势。它能够发现隐匿于周边的视网膜损伤，提高DR检出率，有助于重新认识周边视网膜损伤在DR病理机制中的作用，改进和完善DR分型，指导视网膜激光光凝的治疗方案，减少新生血管性青光眼的发生，对控制病情发展具有重要作用。该文对超广角眼底成像在DR中的诊疗价值及应用进展作一综述。

Diabetic retinopathy (DR) is one of the leading causes of visual impairment among adults worldwide. As a novel fundus imaging technology in recent years, ultra-wide-field imaging can capture approximately 80% of the retina surface with the advantages of wide image, easier operation, more rapid acquisition, no pupil dilation and high resolution. It is useful in identifying latent peripheral lesions and improving positive detection rate of DR. It will assess the pathogenesis of periphery retina in DR comprehensively, promote development of classification and laser photocoagulation, reduce the incidence of neovascular glaucoma, and play an important role in restraining pathological development. This article presented a review on the clinical value and research advances of ultra-wide-field imaging inDR.
