Which of the following factor is related to diabetic retinopathy?
Correct Answer: Duration of disease
Description: Duration of DM and degree of glycemic control are the best predictors of the development of retinopathy; hypeension is also a risk factor. Nonproliferative retinopathy is found in many individuals who have had DM for >20 years (25% incidence with 5 years, and 80% incidence with 15 years of type 1 DM). Although there is genetic susceptibility for retinopathy, it confers less influence than either the duration of DM or the degree of glycemic control. Ref: Powers A.C. (2012). Chapter 344.
