目的：评价欧堡Daytona 200度超广角激光扫描检眼镜检查近视患者眼底周边部视网膜病变的应用价值。方法：本研究为前瞻性病例研究，收集爱尔眼科医院要求行屈光手术的近视患者1 000例(2 000只眼)，分别进行小瞳下欧堡Daytona 200度超广角激光扫描检眼镜眼底检查和散瞳后三面镜检查，记录检查结果并进行比较分析。结果：通过欧堡Daytona 200度超广角激光扫描检眼镜检查发现有周边视网膜病变共230例(310只眼)，检出阳性率为15.50%；三面镜检查发现周边部视网膜病变共242例(322只眼)，检出阳性率为16.10%。两种检查方法对近视患者周边部视网膜病变检出阳性率具有很好的一致性(Kappa值0.8~1.0)。结论：欧堡Daytona 200度超广角成像系统为检查周边部视网膜病变提供了更省时高效的方法，在屈光手术前筛查视网膜周边部病变，具有广阔的临床应用前景。

Objectives: To evaluate the clinical value of peripheral retinal diseases in myopic patients examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona). Methods: This was a prospective case-control study. We collected 1 000 myopic patients (2 000 eyes) who were scheduled to undergo refractive surgery in Aier Eye Hospital. They were examined by 200-degree ultra-wide field laser ophthalmoscope (Daytona) with non-mydriasis and three-mirror contact lens with mydriasis. The examination results were recorded and statistically analyzed. Results: A total of 230 cases (310 eyes) with peripheral retinopathy were found by 200-degree ultra-wide field laser ophthalmoscope (Daytona). The positive rate was 15.50%; 242 cases (322 eyes) with peripheral retinopathy were found by three- mirror contact lens, and the positive rate was 16.10%. The two methods were consistent in the detection of peripheral Retinopathy in myopic patients (the Kappa value is between 0.8 and 1.0). Conclusion: 200-degree ultra-wide field laser ophthalmoscope (Daytona) is an effective and rapid method for detecting peripheral retinopathy. It provides a broad clinical application prospects for peripheral retinopathy screening before refractive surgery.

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.
