Nine, diabetes disease

1, What is diabetic retinopathy?
Patients with diabetes as a result of long-term hyperglycemia, metabolic disorders, caused by systemic microcirculation. Fundus retinal vascular easily damaged, that is, the occurrence of diabetic retinopathy (diabetic retinopathy, DR). Diabetic retinopathy is one of serious complications of diabetes as well as patients with diabetes caused by one of the main reasons blindly.
Epidemiological investigation showed that about 75% of non-importance of glycemic control in diabetic patients, 15 years occurred in the incidence of diabetic retinopathy. In diabetic patients, the occurrence of diabetic retinopathy, and more than 50%.
Diabetes pathological damage caused by the body due to high blood sugar on the micro-vascular damage, which allows retinal capillary endothelial cells and pericytes impaired, resulting in the loss of normal capillary barrier function, leakage phenomenon, caused by surrounding tissue edema, hemorrhage, followed by capillary occlusion caused by retinal ischemia, a lack of blood supply and nutrition, resulting in tissue necrosis and angiogenesis growth factor release and therefore resulting neovascularization, which will cause a large number of retinal hemorrhage and vitreous hemorrhage large, resulting in proliferative vitreoretinopathy.Age the greater the longer the duration, the higher the incidence of fundus. Young people than older patients with greater risk, often adverse prognosis. If diabetes can be control in a timely, not only to occur in less damage to the retina at the same time lighter, otherwise retinopathy progressively heavier bleeding occurred repeatedly, resulting in proliferative retinal changes, and even retinal detachment, or complicated cataract.
Diabetic retinopathy have what performance?
Diabetic retinopathy is caused due to diabetes, with the exception of symptoms to more than drink, more food, polyuria and urine, characterized by hyperglycemia, but also have their eyes appear bright red retinal capillary hemangioma, flame-shaped hemorrhage, the latter has gray exudative, bright red neovascularization, high incidence of vitreous hemorrhage red for the main features of the fundus changes.
Does not affect early retinopathy Macular, the vision will not be affected, patients with no symptoms, and sometimes feel vision loss in patients with, or has the immediate shadow flying or fluttering. If the lesion development in 3-5 years or poor blood sugar control, can cause varying degrees of retinal hemorrhage, exudation, edema, hemangioma. Such as the fundus macular involvement, visual acuity may be decreased, the immediate shadow, the dark vision of the Center, the Center for vision and visual symptoms such as metamorphopsia. If retinal repeated bleeding into the vitreous, the patient has consciously eyes fluttering shadow. When the blood vessels or neovascularization massive bleeding into the vitreous cavity, will seriously affect the vision, even blindness.
Urine disease retinopathy should be about the prevention and control?
• blood glucose control in normal or near normal levels, while blood pressure control of 140/90 mmHg in the normal range.
• appropriate control diet, to strengthen the campaign to control blood sugar.
• early detection of vision and fundus, early treatment, to keep vision improve your quality of life.
