摘要

糖尿病视网膜病变(DR)以视网膜血管病变为特征,是视力受损的主要原因。光学相干断层血管造影(OCTA)是一种创新的成像技术,能检测出视网膜微血管的各种病变和可量化的变化。我们简要介绍了它的功能原理以及与荧光素血管造影相比的优势,并对其在糖尿病前期、无临床视网膜病变的糖尿病(NDR)、非增殖性糖尿病(NPDR)、增殖性糖尿病(PDR)和糖尿病黄斑水肿(DME)患者筛查或管理中的临床应用进行了全面回顾。OCTA 可显示糖尿病前期和 NDR 眼球的早期微血管改变,这些改变可能与亚临床神经视网膜功能障碍同时存在。它在 NPDR 中的应用包括测量缺血、检测视网膜新生血管以及通过预测视网膜病变恶化或发展成 DME 的风险来确定早期治疗时机。在 PDR 中,OCTA 有助于描述新生血管复合物内的血流特征,并评估其进展或消退对治疗的反应。在患有 DME 的眼睛中,OCTA 灌注参数可能对治疗带来的视觉和解剖效果具有预测价值。我们进一步讨论了 OCTA 的局限性以及将其纳入最新 DR 严重程度量表的益处。

Optical coherence tomography angiography in diabetic retinopathy: A major review

Diabetic retinopathy (DR) is characterized by retinal vasculopathy and is a leading cause of visual impairment. Optical coherence tomography angiography (OCTA) is an innovative imaging technology that can detect various pathologies and quantifiable changes in retinal microvasculature. We briefly describe its functional principles and advantages over fluorescein angiography and perform a comprehensive review on its clinical applications in the screening or management of people with prediabetes, diabetes without clinical retinopathy (NDR), nonproliferative DR (NPDR), proliferative DR (PDR), and diabetic macular edema (DME). OCTA reveals early microvascular alterations in prediabetic and NDR eyes, which may coexist with sub-clinical neuroretinal dysfunction. Its applications in NPDR include measuring ischemia, detecting retinal neovascularization, and timing of early treatment through predicting the risk of retinopathy worsening or development of DME. In PDR, OCTA helps characterize the flow within neovascular complexes and evaluate their progression or regression in response to treatment. In eyes with DME, OCTA perfusion parameters may be of predictive value regarding the visual and anatomical gains associated with treatment. We further discussed the limitations of OCTA and the benefits of its incorporation into an updated DR severity scale.
