The term diabetic eye disease represents a group of eye problems that people with diabetes may face as a complication of the disease. All of which can cause severe vision loss or even blindness.
Diabetic retinopathy is the most common diabetic eye disease, and a leading cause of blindness in adults. It is caused by changes in the blood vessels of the retina. In some people with diabetic retinopathy, blood vessels may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. The retina is the light-sensitive tissue at the back of the eye. A healthy retina is necessary for good vision. If you have diabetic retinopathy, at first you may not notice changes to your vision. However, over time, diabetic retinopathy can get worse and cause vision loss. This condition, usually affects both eyes.
