The retina is light- sensitive tissue of the eye. Retinopathy (damage to eye) occurs when diabetes damages the tiny blood vessels in the retina. This damage can lead to problems with your vision including blindness.
High blood sugar levels damage small blood vessels. The weakened blood vessels may break and leak fluid and blood. Also, new abnormal blood vessels may grow. These new blood vessels can bleed, cause cloudy vision, and destroy the retina.
ADA recommends comprehensive eye examination by an ophthalmologist shortly after the diagnosis of diabetes and once a year thereafter.
