摘要
糖尿病黄斑水肿(DME)是糖尿病视网膜病变患者中心视力丧失甚至失明的首要原因。相较于传统的FFA检查,OCT能快速获得高分辨率的三维立体图像,从而便捷地反映眼底组织的细节并实现定量测量。OCT血管成像(OCTA)作为一种新兴的血管成像技术,对观察视网膜及脉络膜不同层面的血管结构形态,量化一定范围内的血流密度及病灶面积有其无可比拟的优势。因此,结合OCT和OCTA的检查结果对DME患者进行形态学、血管及血流定性和定量分析,对DME的诊断及分型、指导治疗、评估预后具有指导性作用。
Diabetic macular edema is the leading cause of central vision loss and even blindness in diabetic retinopathy.Compared to FFA,OCT can obtain the high-resolution 3D image quickly,easily to reflect the details of the tissue and realize the quantitative measurement.As a novel technology,OCT angiography(OCTA)can display microvascular structure from different layers of retina and choroid,having its advantage of quantifying the vessel density and the lesion area.By detecting fundus morphology,quantifying and quantitating the retinal vessels and vessel density,the combination of OCT and OCTA could play a guiding role in diagnosis,classification,treatment and prognosis of diabetic macular edema.
