Diabetic retinopathy, referred to as glucose retinopathy, is one of the most common microvascular complications of diabetes and is related to the length of diabetes, individual variability, and the level of control of blood pressure, blood glucose, and lipids. Long-term diabetes can lead to retinal detachment, creating a state of blindness. The treatment of glucose retinal disease mainly includes the following points: 1, control of blood sugar, blood sugar is the root cause of diabetic complications, only good control of blood sugar can slow down the development of glucose retinal disease. 2, to improve circulation, anti-oxidative stress treatment, such as calcium hydroxybenzene sulfonate, lipoic acid, etc. 3, retinal photocoagulation therapy, the use of laser treatment to destroy neovascularization, close the leaking blood vessels to avoid further development of the lesion to prevent retinal detachment. There is no effective treatment for diabetic retinopathy, and it is difficult to reverse once it appears. Therefore, diabetic patients need to strictly control blood glucose from the time of diabetes diagnosis to avoid the development and progression of complications.
