Retinopathy is a complication of microangiopathy in diabetic patients, in the human body blood vessels with high sugar content, with the prolongation of time, a variety of tissues within the human eye will occur qualitative changes in the vascular wall tissue is the most obvious, manifested in the early stage of small hemangiomas, small hemorrhagic spots, when the patient does not yet have vision loss, and also not to the hospital for examination. With the prolongation of time, macular degeneration, retinal hemorrhage and exudation, vitreous hemorrhage, proliferation and even retinal detachment, vision is greatly reduced until blindness. At this time, then check and treat, has lost the best time for treatment. Therefore, diabetic patients should go to the eye hospital for regular checkups and early treatment is necessary. Among all the treatments, the most fundamental is to keep the blood sugar within the normal index range, which is the most basic treatment for diabetic fundopathy. Without this foundation, other treatments will be futile. Diabetic patients should be reminded to routinely have their fundus examined once a year and have their fundus photographed for comparison. For those who have developed fundus disease, they should be examined once every three to six months. In addition, prevention is the most important aspect of diabetic retinopathy. Once diagnosed with diabetes, the fundus should be examined in an ophthalmology clinic for early detection of lesions and treatment. Specific treatments mainly include the following: 1, active control of primary disease: early diagnosis of diabetes, early control of diabetes using dietary control, oral hypoglycemic drugs or insulin injections, as well as appropriate exercise and other measures to control diabetes, is to prevent, delay or mitigate diabetic retinopathy. 2.Laser treatment: It can directly coagulate and close neovascularization, microangioma and capillaries with fluorescence leakage, stop vitreous hemorrhage and retinal edema without affecting the function of macula. When treating neovascularization with laser, it closes its feeding artery first and coagulates the retina around it at the same time, so as to make it turn from hypoxic state to non-oxygen-demanding state, so it can reduce the production of neovascularization or make it atrophy. However, it is necessary to make laser supplemental treatment every year to close the incipient neovascularization. 3, vitrectomy: in recent years, for proliferative diabetic retinopathy, can be used to remove intravitreal mechanized material of the treatment method, in order to prevent traction retinal detachment, and improve visual acuity. 4, drug conservative treatment: diabetic retinopathy is due to microangiopathy in the retinal microcirculation with the formation of microthrombi, so the following drug therapy can be used: antiplatelet coagulant drugs, such as aspirin, Pansentin, Danshen, etc.; anticoagulant drugs, heparin on behalf of the; pro-fibrinolytic drugs, urokinase, streptokinase on behalf of the.
