Diabetic retinopathy is a disease affects diabetic people and eventually leads to blurry, distorted vision and blindness.
When people suffer with diabetes they may often have unstable glucose levels and they are prone to circulation problems in the back of the eye, known as the Retina. The retina is a very sensitive part of the eye that is responsible for interpreting the images that you see and then transmitting these images to the brain. In the case that someone is diabetic they may experience a restriction on the flow of blood through the vessels within the retina. When this restriction occurs swelling, bleeding and even hemorrhaging may result. Aside from the threat of blood, sometimes fluid can collect under the Retina-this problem is known as macular edema.
Many diabetic patients 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.
