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.
