视网膜疾病大多以周边视网膜病变为首要表现，后者的早期诊断、监测对于视网膜疾病的治疗及预防起着至关重要的作用。以往传统眼底成像技术仅能提供20°视网膜的可视范围，即便使用蒙太奇拍摄技术，也只能采集部分眼底范围。目前眼底成像技术已步入最新的超广角时代，其所提供的眼底视野至少可达200°，并且基于该技术的超广角眼底彩色照相、荧光素血管造影、光学相干断层扫描及其血管造影等已广泛应用于临床实践中，对于诊断及评估视网膜疾病发挥重要作用，如糖尿病性视网膜病变、视网膜静脉阻塞、早产儿视网膜病变、视网膜色素变性及视网膜脱离等。本文将从超广角成像技术的产生、发展及其国内外的临床应用现状作一综述，旨在为临床工作及研究提供指导意义。

Retinal diseases primarily feature with peripheral retinopathy, and its early diagnosis as well as the later following up both play a vital role in the treatment and prevention of retinal diseases. In the past, traditional fundus imaging technology can only provide the visual range of 20 degrees. Even if montage photography technology is used, it can only partially reveal the fundus field. At present, fundus imaging technology has entered the latest era of ultra-wide-field, which provides at least 200-degree fundus field of vision. Ultra-wide-field fundus photochromy, fluorescein angiography, optical coherence tomography and angiography based on this technology have been widely used in clinical practice, and play an important role in the diagnosis and evaluation of retinal diseases, such as diabetes retinopathy, retinal vein occlusion, retinopathy of prematurity, retinitis pigmentosa and retinal detachment. This article aims to review the occurrence and development of ultra-wide-field fundus imaging technology and its clinical applications up to now to provide a relative guideline for clinic and research.
