The retina is the part of the eye that receives light to allow a person to see. The tissue and cells of the retina are fed by the retinal vessels. The high levels of glucose seen with diabetes leads to damage of the blood vessel wall causing leakage into the retina. This leads to blurry vision. Eventually, the damage leads to growth of new abnormal vessels. Abnormal vessels can bleed into the retina causing scarring and blindness. Diabetes is the leading cause of blindness in young people.
