Diabetic Retinopathy

Diabetic retinopathy is a complication from diabetes that affects the eyes. It sometimes leads to partial vision loss and eventually results in blindness. The leading cause of blindness in adults, diabetic retinopathy is caused by damage to or swelling of the blood vessels in the back of the eye (the retina), which is constructed of light-sensitive tissue. In some cases, blood vessels can leak fluid into the eye's macula causing blurred vision. In other cases, new blood vessels grow abnormally, attaching to the surface of the retina. Anyone with type 1 or type 2 diabetes is at risk but especially longtime diabetics and those with less controlled blood sugar levels.
