What is diabetic retinopathy (diabetic eye disease)?

Diabetes is a condition where high level of glucose in the blood causes damage to organs in the body. The retina is one of the most vulnerable parts of the body that can be damaged by diabetes, a condition known as diabetic retinopathy. Diabetes causes damage to the blood vessels of the retina, a thin and delicate tissue that is responsible for vision. In some people suffering from diabetic retinopathy, blood vessels swell and leak fluid. In others, abnormal new blood vessels grow on the surface of the retina that can lead to bleeding and retinal detachment. These changes in the retina causes vision loss. A healthy retina is necessary for good vision. If you have diabetic retinopathy, you may not notice any change to your vision at first. Gradually, the condition can worsen and cause vision loss. Diabetic retinopathy usually affects both eyes, it is therefore very important for early detection and prompt treatment to minimize vision loss.
