糖尿病视网膜病变(DR)是糖尿病最常见和严重的微血管并发症,也是造成20-65岁成年人失明的首发原因。视网膜光凝术可减少新生血管的生成,阻止糖尿病视网膜病变的进一步发展,从而有效稳定病情[1]。但激光本身也是一种病理过程,对视网膜产生光损伤可能造成患者视功能的下降。本研究将明睛合 Diabetic retinopathy (DR) is the most common and serious microvascular complication of diabetes mellitus, and is also the leading cause of blindness in adults aged 20-65 years. Retinal photocoagulation can reduce the formation of neovascularization, prevent the further development of diabetic retinopathy, so as to effectively stabilize the condition [1]. However, the laser itself is also a pathological process, light damage to the retina may result in decreased visual function in patients. This study will be bright eyes together
