What to do about diabetes-associated eye disease
Millions of people in the world suffer from Diabetis. There are a lot of side effects to this disease and one of them is diabetis can cause lost of eyesight. It is a condition known as Diabetic retinopathy which affects the blood vessels in the retina of the eye.
What causes retinopathy is unknown but it occurs in two stages. The first stage being the weakening of the walls of the small blood vessels that eventually become abnormal. Fluid leaks into surrounding tissue leaves deposits of protein and fat called hard exudates, then vessels develop micro aneurysms. Micro aneurysms are tiny bulges or pockets in their walls that tend to leak red blood cells into the retina causing abnormalities that robs the retina of its blood supply. Nerve fibers then died off due to poor circulation and lack of oxygen, creating white cottony patches known as soft exudates. These changes may not alter your vision may eventually impair your eyesight.
