Blood vessel problems are a common diabetes complication. Having diabetes increases a person’s risk of developing coronary heart disease and it makes the disease worse by damaging the small blood vessels of the heart. They found that nerve damage in the retina precedes the development of abnormal blood vessels normally blamed for vision loss in diabetic retinopathy. The exact connection between this vessel damage and Alzheimer’s disease isn’t exactly clear, he added. It helps out the enzymes which are involved in methylation pathways. Early detection of eye disease can help prevent permanent damage. Non-proliferative Diabetic Retinopathy, or Background Diabetic Retinopathy (BDR), is caused by leakage of the tiny retinal blood vessels.
The second stage of the disease is pre-proliferative retinopathy, which is when more severe changes begin to become evident in the retina. Sometimes, deposits of cholesterol or other fats from the blood may leak into the retina
