Diabetic macular edema (DME) is characterized by a retinal thickening or hard exudation deposition in the fundus microvasculature, capillary leakage, increased vascular permeability, extracellular fluid accumulation in the fovea of a foveal disc. Optical coherence tomography angiography (OCTA) is a new item of fundus structure examination. OCTA is to reconstruct the retinal choroidal vascular structure from the continuous same cross-sectional views and blood flow signals obtained by optical scanning, thereby obtaining an image. It is very significant to evaluate, diagnose, treat and manage the disease.
糖尿病性黄斑水肿(DME)的特征是眼底微血管中视网膜增厚或硬性渗出物沉积、毛细血管渗漏、血管通透性增加、黄斑中心凹的细胞外液积聚。光学相干断层扫描血管造影(OCTA)是眼底结构检查的新项目。OCTA 是通过光学扫描从连续的相同横截面视图和血流信号中重建视网膜脉络膜血管结构,从而获得图像。它对评估、诊断、治疗和管理疾病具有非常重要的意义。
