Diabetic eye disease is very closely related to blood glucose, so from the day you are diagnosed with diabetes, you need to pay attention to the prevention of eye disease. A fundamental requirement is to strictly regulate the control of blood glucose to meet the standard. Research has proven that early and effective control of blood glucose to the normal range can effectively reduce the occurrence of diabetic eye disease, or delay the development of eye disease. Diabetic patients who do not have diabetic eye disease should allow endocrinologists to develop an effective treatment plan, including oral hypoglycemic drugs, or insulin, dietary therapy, exercise therapy, and other methods to control the diabetic condition. This is the fundamental principle of prevention and treatment of diabetic eye disease. Secondly, for diabetics with comorbidities such as high blood pressure and high blood cholesterol, diabetic ophthalmopathy occurs and develops more rapidly, so controlling blood glucose and stabilizing blood pressure are important aspects. For diabetic eye lesion treatment, there is no specific drug that can effectively treat diabetic eye lesions. Once the eye disease occurs, there is no cure. Only symptomatic treatment, slow down the development of the disease, not a cure. Some proprietary Chinese medicines have preventive and therapeutic effects on diabetic eye disease, such as Compound Thrombolysis, Salvia divinorum and so on. Therefore, for the prevention of diabetic eye disease, it is advisable to do it early, not wait until it has already occurred and then treat it, then it will be too late.
