Diabetes-related elevated blood sugar results in diabetic retinopathy. Your retina, which detects light and transmits information to your brain via a nerve in the back of your eye, can become damaged over time if there is too much sugar in your blood.
New blood vessels might develop when diabetic retinopathy worsens and endanger your vision. Over time, having too much sugar in your blood can cause the little blood capillaries that feed the retina to become blocked, so severing the retina's blood supply. The eye makes an effort to generate new blood vessels as a result.
