Chronic complications of diabetes -- eye diseases

Diabetics prone to the lens, vitreous fluid and retinal lesions, especially retinal changes for the current visual impairment occurred the main factors. The lesions lens : the lens opacity as a result of the symptoms called "cataract." With diabetes-related cataract usually have two types : a "snow flake cataract" diabetes in young people, due to poor control of diabetes occurred, and progress at a fairly rapid pace, clinical, This type of rare cases. The second "senile cataract", compared with normal subjects, people suffering from diabetes symptoms such opportunities and not necessarily higher only suffering from diabetes in this disease, its progress faster, in other words, lead to visual impairment will be the case earlier, so essential for the early removal of the lens surgery. Retinal lesions : Since insulin and oral hypoglycemic drugs available, the life expectancy of diabetics has been greatly extended, But, correspondingly, the incidence of retinopathy rate has gradually occurred. The basic retinal microvascular changes to the expansion of small hemangioma and vascular sclerosis. Next is the proliferation of retinitis, we can see the phenomenon of angiogenesis. Vascular breeding results have traction, so retinal vascular rupture or peeling. In general, suffering from diabetes, the more long, its incidence of retinopathy higher. However, the quality of diabetes control and the incidence of retinopathy in the relationship, so far, has not been determined. According to French media reports, the number of daily injections of short-acting insulin, contribute to the reduction of retinal small hemangioma happening. Another report indicated that the insulin injection well, will enable the proliferation of retinal change mitigation. Vitreous hemorrhage, and retinal vascular usually proliferation are closely related and proliferation of vascular traction, vitreous backend can peeling off, falling off the vessel, the blood went to make vitreous humor Lane, which leads to visual obstacles. The treatment of eye diseases : cataract treatment with non-diabetic patients, no particular difference But before the surgery, diabetes control as possible, after surgery the chance of an accident occurring will be less and less. Retinal fundamental changes, usually without treatment, but if the vascular changes very close to the most sensitive visual macular site, caused by macular edema, can be photocoagulation therapy, but the results have yet to be confirmed. Proliferative retinopathy, it would seriously harm the patient's eyesight and even blind patients, therefore necessary to be active treatment. The most common approach is photocoagulation, in the United States and Britain have a large-scale clinical study, revealed that the treatment of patients eyesight protection does help. However, the necessary stress is that not all treated patients suffered its benefits. A few patients not only of no help Anti-victimized.
