Ophthalmic advices:Diabetes and eye health
The diabetes mellitus is a disease in which the body is reduced ability to store and use the sugar. High levels of blood sugar cause changes in the body and facilitate the development of cardiovascular problems (such as angina, heart attack, hypertension) and kidney failure among others. In the eyes may occur diabetic retinopathy and facilitates the appearance of cataract and glaucoma among other problems.
The diabetic retinopathy is a condition of retina, in which a characteristic damage occurs as a result of metabolic stress of diabetes that affects mainly the vessels. It is caused by damage maintained by high levels of sugar in the blood vessels that nourish the retina, the lack of nutrition in some areas of the retina and the development of new vessels. The affected vessels are malfuncionantes and weak, they drain their liquid content causing macular edema that is the leading cause of vision loss in diabetics. The new vessels grow in the rest of the retina and the optic nerve, are fragile and can break causing bleeding inside the eye in the form of eye hemorrhage. The vessels may grow into the pulling eye and causing the retina retinal detachment. The growth of vessels can proceed toward the iris causing a very aggressive type of glaucoma and very difficult to treat than is the neovascular glaucoma. Diabetic retinopathy is the leading cause of blindness in adults and may respond well to attention and appropriate treatment. It is very important to ophthalmologic examinations in diabetic patients even without discomfort.
It is very important to make early diagnosis of retinopathy to protect vision. The ophthalmologic examinations should start when diabetes is detected and must be closely monitored even though the patient has no discomfort, because in many cases patients can remain undisturbed for many years until the damage already it is very serious and irreversible. It is important to insist on making a very strict controlling sugar levels, blood pressure, renal function and lipids. If good control is the ophthalmologist can begin treatment before sight is affected.
