Diabetic retinopathy is a disease that leads to blurry, distorted vision and blindness. It occurs when diabetes weakens blood vessels inside your eye. These weak vessels leak fluid into the retinal area. New, distorted vessels may grow, and then bleed. These vessels can damage areas of the retina, causing vision loss.
You can have diabetic retinopathy without knowing it. Usually, there is no pain and no outward sign. Over time, you may notice gradual blurring or some vision loss. Symptoms may come and go. If diabetic retinopathy is severe, you may have clouded vision or blindness. You should have regular eye exams to help your doctor detect changes in your eyes before your vision is damaged.
Treatment may help slow the progress of diabetic retinopathy and sometimes can restore lost vision. Your treatment depends on your condition, but may include frequent exams to monitor your condition, laser treatment, surgery or other procedures.
