Purpose of Review

For over 50 years, diabetic retinopathy (DR) has been classified by pathologic features seen on clinical examination and conventional retinal photographs. However, newer technology such as optical coherence tomography angiography (OCTA) now enables rapid acquisition of retinal structural and vascular information in a reliable, non-invasive, high-resolution fashion. Here, we highlight recent studies that have explored wide field swept-source OCTA (WF SS-OCTA) for the diagnosis and management of DR.

Recent Findings

Multiple studies have demonstrated the utility of WF SS-OCTA for detection of all clinically relevant features of DR. An updated DR staging system is proposed that leverages the advantages of WF SS-OCTA, including the ability to correlate detailed vascular and structural pathology over time with longitudinal imaging.

Summary

WF SS-OCTA has tremendous potential for evaluating patients with DR. A new WF SS-OCTA-based staging system may be useful in routine clinical practice and for clinical trials.

使用广域扫描源光学相干断层扫描血管造影建立糖尿病视网膜病变的新分期系统

审查目的

50 多年来，糖尿病性视网膜病变 (DR) 一直根据临床检查和传统视网膜照片中的病理特征进行分类。然而，光学相干断层扫描血管造影 (OCTA) 等新技术现在能够以可靠、无创、高分辨率的方式快速获取视网膜结构和血管信息。在这里，我们重点介绍了最近的研究，这些研究探索了用于 DR 诊断和管理的广域扫频源 OCTA (WF SS-OCTA)。

最近的发现

多项研究证明了 WF SS-OCTA 可用于检测 DR 的所有临床相关特征。提出了一种更新的 DR 分期系统，该系统利用了 WF SS-OCTA 的优势，包括将详细的血管和结构病理随时间与纵向成像相关联的能力。

概括

WF SS-OCTA 在评估 DR 患者方面具有巨大潜力。一种新的基于 WF SS-OCTA 的分期系统可能对常规临床实践和临床试验有用。
