Abstract
Diabetic retinopathy (DR) is one of the major microvascular complications of diabetes.(5) It is one of the most common cause of preventable blindness in diabetic adults. A study of over 44,000 individuals from 9 countries,7 which evaluated fasting and 2-h postprandial plasma glucose and HbA1c levels found a curvilinear plot of diabetic retinopathy versus HbA1c, and suggested a threshold for the diagnosis of diabetes, based on several different statistical criteria, defined by the presence of diabetes-specific retinopathy in this large population as a function of HbA1c level. The statistical cutoff point for this diagnosis was determined to be an HbA1c threshold of >6.5%, which is the accepted international standard.
