Diabetic retinopathy (DR) is a complication of diabetes mellitus, a disorder of glucose metabolism that affects all organs and tissues of the body, of which DR is one of the serious complications of diabetes mellitus and the first or second of the four major blindness-causing eye diseases in Europe and the United States. As the number of diabetic patients in China is increasing, the number of DR patients is also increasing, and the trend is rising year by year. The onset of the disease is not related to gender and age, but is very closely related to the course of diabetes. The incidence of fundus lesions increases gradually with the duration of diabetes, and the disease also gradually worsens, according to statistics, 25% of those with a disease duration of more than five years, 60% of those with a disease duration of more than ten years, and 75% of those with a disease duration of more than fifteen years. The more severe the disease, the greater the chance of its development. As a result of damage to the retinal capillary wall caused by diabetes mellitus, fundus hemorrhage and exudation occur. Clinically, according to the performance of the fundus, it can be divided into the following two types and six stages from mild to severe: Simple type Stage I: the retina has microvascular tumors or small hemorrhages. Stage II: Yellowish-white “hard exudate” or hemorrhagic spots in the retina. Stage III: White “cotton wool spots” or hemorrhagic spots in the retina. Proliferative stage IV: retina with neovascularization and/or vitreous hemorrhage. Stage V: retina with neovascularization and fiber proliferation. Stage VI: retina with neovascularization and fibrous proliferation complicating retinal detachment. For the diagnosis of this disease, the most important thing is based on the patient’s medical history, diabetes is its premise, at the same time, when examining the fundus, once DR is found, fundus fluorescence angiography should be performed to determine the stage that is in DR and treat accordingly, therefore, as a diabetic patient, you should regularly go to the hospital ophthalmology to check your eyes, especially those patients who have diabetes for more than 5 or 10 years, to If you find that your eyesight is declining, you should see an ophthalmologist immediately to achieve early detection and early treatment, to preserve effective vision, and to try to control the disease to the least degree, and the treatment effect will be better. The treatment of the disease, in different periods, the treatment is different, in the background, and not found in the non-perfusion zone, the treatment is mainly to take medication, and once found in the non-perfusion zone and the development of the proliferation phase, the fundus laser and surgical treatment, but at this time the treatment is also more passive and negative, but this is the only way, therefore, for diabetic patients, in good control of blood sugar Therefore, for diabetic patients, it is important to pay close attention to DR while controlling blood sugar well, and when DR is found, it should be treated early to try to avoid progressing to the proliferative stage, which will affect the treatment effect. However, if it develops to the proliferative stage, laser and surgery are the best treatment methods, and together with traditional Chinese medicine, the treatment of the disease is still ideal. (For example, in the previous period of time, an outpatient reported a sudden loss of vision in the right eye for 3 days, and the examination revealed a small amount of blood in the vitreous of the right eye, and a large amount of punctate hemorrhage and exudation in the retina, while there is a stripe-like proliferating membrane in front of the retina, but no retinal detachment has occurred yet, this situation is the V stage of DR.)
