Purpose of Review

Early detection and treatment are important for preventing vision loss from diabetic retinopathy. Historically, the gold standard for grading diabetic retinopathy has been based on 7-field 30-degree color fundus photographs that capture roughly the central third of the retina. Our aim was to review recent literature on the role of ultra-widefield (allowing capture of up to 82% of the retina in one frame) fundus imaging in screening, prognostication, and treatment of diabetic retinopathy.

Recent Findings

Ultra-widefield fundus imaging can capture peripheral retinal lesions outside the traditional 7-field photographs that may correlate with increased risk of diabetic retinopathy progression. The speed and ability to image through undilated pupils make ultra-widefield imaging attractive for tele-ophthalmology screening. Ultra-widefield fluorescein angiography may help guide targeted laser treatment in eyes with proliferative diabetic retinopathy.

Summary

Ultra-widefield imaging has potential to help shape new diabetic retinopathy screening, staging, and treatment protocols.

超广角眼底成像和荧光血管造影在糖尿病视网膜病变诊断和治疗中的作用

审查目的

早期发现和治疗对于预防糖尿病视网膜病变导致的视力丧失很重要。从历史上看，糖尿病视网膜病变分级的金标准是基于 7 视野 30 度彩色眼底照片，这些照片大约捕获了视网膜中央的三分之一。我们的目的是回顾最近关于超宽视野（允许在一帧中捕获多达 82% 的视网膜）眼底成像在糖尿病视网膜病变的筛查、预后和治疗中的作用的文献。

最近的发现

超宽视野眼底成像可以捕捉传统 7 视野照片之外的周边视网膜病变，这些病变可能与糖尿病视网膜病变进展的风险增加有关。通过未散瞳的瞳孔成像的速度和能力使超广角成像对远距眼科筛查具有吸引力。超宽视野荧光素血管造影可能有助于指导增殖性糖尿病视网膜病变眼的靶向激光治疗。

概括

超宽场成像有可能帮助塑造新的糖尿病视网膜病变筛查、分期和治疗方案。
