Diabetes is one of the leading causes of blindness. I just examined a 43 year old who has a 20 year history of diabetes. He stated that his sugar has not been under the best of control and has not his eyes checked for about five years. The patient did have a small amount of diabetic change in the back of the eye for which we referred. Diabetics should have their eyes examined no less than once per year and more if eye problems are discovered. It could make the difference of possibly saving one's vision.
