1, What is diabetic retinopathy?
Long-term blood sugar in diabetic patients as a result of increased metabolic disorder, caused by systemic microcirculation. Fundus easily damaged retinal blood vessels, which occurred in diabetic retinopathy (diabetic retinopathy, DR). Diabetic retinopathy is one of serious complications of diabetes, diabetes is also one of the main reasons caused by the blind.
Epidemiological survey 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, there is leakage, resulting in surrounding tissue edema, bleeding, followed by the occlusion of capillaries caused by retinal ischemia, a lack of blood supply and nutrition, resulting in tissue necrosis and neovascularization of the release of growth factors and thus generated new blood vessels, which will lead to a large number of retinal hemorrhage and vitreous hemorrhage in a large number of produce proliferative vitreoretinopathy. The greater age, longer duration, higher incidence of fundus. Than young people a greater risk of the elderly patients, often adverse prognosis. If control of diabetes mellitus can be timely, not only to occur in less damage to the retina at the same time lighter, otherwise progressive retinopathy, recurrent bleeding occurred, resulting in proliferative retinal changes, and even retinal detachment, or complicated cataract.
Diabetic retinopathy What performance?
Diabetic retinopathy is caused due to diabetes, with the exception of symptoms to more than drink, more food, more urine and urine, characterized by elevated blood sugar, there will also be bright red eyes appeared retinal capillary hemangioma, flame-shaped hemorrhage, the latter are off-white exudative, bright red neovascularization, vitreous prone to blood red as the main features of the fundus changes.
Does not affect the early eye macular lesions, the vision will not be affected, patients with no symptoms, and sometimes feel that patients with vision loss, or have a shadow before flying or fluttering. If the lesion development of 3-5 years or poor blood sugar control, can cause varying degrees of retinal hemorrhage, exudation, edema, hemangioma. Macular involvement, such as fundus, visual acuity may be decreased, the immediate shadow, the dark vision of the Center, the decline in visual acuity and visual symptoms such as metamorphopsia. Repeated if the retina into the vitreous hemorrhage, 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 your vision to improve the quality of life.
