糖尿病视网膜病变 (DiabeticRetinopathy ,DR)是糖尿病最常见的并发症之一。多年来对其发病机理的研究主要集中在视网膜毛细血管微循环的改变上 ,而对视网膜神经组织的研究较少。事实上 ,视网膜是由血管和神经元组成的复杂结构 ,主要由神经网膜组成 ,神经细胞构成了神经网膜的 Diabetic Retinopathy (DR) is one of the most common complications of diabetes. For many years, the research of its pathogenesis mainly focused on the changes of retinal capillary microcirculation, but less on the retina nerve tissue. In fact, the retina is a complex structure composed of blood vessels and neurons, mainly composed of the neural network, the nerve cells constitute the neural network
