Types of Eye Diseases in the Retina
Types of Eye Diseases in the Retina, There are three types:
1. Macular degeneration. For more information click here
2. Diabetic retinopathy as detailed below.
3. Retinal detachment. For more information click here
Diabetic retinopathy is caused by changes in blood vessels of the retina. In some people with diabetic retinopathy, retinal blood vessels may swell and leak fluid, while in others, abnormal new blood vessels grow on the surface of the retina. These changes can result in vision loss or blindness.
Diabetic retinopathy can not be completely avoided, but the risk can be greatly reduced. Better control of the level of blood sugar slows the onset and progression of retinopathy and lessens the need for laser surgery for severe retinopathy.
You may not have symptoms or pain in the beginning stages of diabetic retinopathy and vision may not change until the disease progresses.
A condition called macular edema may occur when the macula, a part of the retina, swells from the leaking fluid and causes blurred vision. When new vessels grow on the surface of the retina, they can bleed (hemorrhage) inside the eye, blocking vision.
Effects of Diabetes on the Body
Diabetes is a disease of worldwide distribution. The term diabetes, considered in isolation, means pass through . This concept was attributed many centuries ago of an alleged kidney disorder responsible for the production of polyuria, one of the hallmarks of the disease. From a clinical standpoint, diabetes mellitus usually occurs in two stages of life, denominating juvenile diabetes to that observed mainly in adolescence or young adulthood and adult diabetes, one that affects a mature individual.
Glucose Metabolism
The glucose goes into the tissues in order to provide the basis for the same energy. The cells incorporate it in two ways: 1) through insulin used as a transport, and 2) without the hormone. Tissues that require the participation of insulin to glucose incorporation, such as resting muscle tissue and adipose tissue, called insulin, and those that do not require the hormone to incorporate glucose, such as the brain, called insulin-dependent tissues. The active muscle tissue behaves as non-insulin-made which is recommended for diabetic patients in sport.
