Sugar Land - Visiting Nurse Assn. Diabetic eye disease refers to a group of eye problems that people with diabetes may face as complications. All can cause severe vision loss or even blindness. Diabetic eye disease can often be treated before vision loss occurs. All people with diabetes should have a dilated eye exam at least once a year.
Diabetic retinopathy is a leading cause of blindness in American adults.
It is caused by changes in the 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 may result in vision loss or blindness. Diabetic retinopathy cannot be completely avoided, but the risk can be greatly reduced. Better control of blood sugar level slows the onset and progression of retinopathy and lessens the need for laser surgery for severe retinopathy.
