Diabetes marker could miss complications

A recent study has highlighted that the blood sugar levels at which damage to the eye starts to happen is well below the threshold for diagnosis. Diabetes is usually diagnosed using fasting blood sugar levels.
However, retinopathy, a common complication of the disease that in many cases leads to eventual blindness, starts at blood sugar levels well below that considered to be diabetic . The results were gleaned by an Australian research team at the University of Melbourne .
Lead researcher Dr. Wong, of the university, was reported as commenting: “Retinopathy, which is one of the complications traditionally associated with diabetes, occurs at fasting glucose levels below the threshold that is used to define diabetes.”
