关注糖尿病黄斑水肿的光学相干断层扫描分型及相关影像特征

糖尿病性视网膜病变(DR)是目前成人第一致盲眼病。其中,糖尿病性黄斑水肿(DME)是导致糖尿病患者中心视觉功能严重障碍的主要原因。DME不同表现及分型对确定其严重程度及选择治疗方式至关重要。光学相干断层成像(OCT)是目前测量视网膜厚度,评估DME形态及微细结构的主要检查手段。DME的OCT检查有多种形态表现及伴随影像,各种表现反映不同的病理基础。为此,笔者强调通过DME形成机制,理解DME病理基础上的OCT分型方法,掌握相关影像特征及其临床意义,为判断疾病严重程度、选择治疗方案及疾病的预后提供更明确的信息。

Pay attention to OCT-based classification and features of diabetic macular edema

Diabetic retinopathy(DR)is the most common cause of blindness in adults.Among of them,diabetic macular edema(DME)is the major cause of severely impaired central vision for diabetic patients.Different manifestations and classifications of DME are important to determine the severity,outcome assessments and treatment of DME.Optical coherence tomography(OCT)is a main imaging method to measure retinal thickness and evaluate the morphology and microstructure of DME.The OCT-based classifications and related image features of DME is available to map different pathological basis.Therefore,we stress the importance of DME types and associated features on the pathological mechanism of DME in this paper,aiming to determine the severity of the disease,select optimal treatment,and may provide information for the prognosis of the disease.
