CGM Use Associated with Significantly Lower Risk of Developing Diabetic Retinopathy

A retrospective cohort study published in JAMA Network Open showed that CGM use was associated with lower odds of developing diabetic retinopathy (DR) and proliferative diabetic retinopathy (PDR). Among 550 adults with type 1 diabetes (T1D) included in the analysis, 62.7% patients used CGM, 58.2% used an insulin pump, and 47.5% used both. After adjusting for age, sex, race and ethnicity, diabetes duration, microvascular and macrovascular complications, insurance type, and mean HbA1c, CGM was associated with lower odds of DR (odds ratio [OR], 0.52; 95% CI, 0.32-0.84; P=0.008) and PDR (OR, 0.42; 95% CI, 0.23-0.75; P =0.004), compared with no CGM use. These findings show that CGM can be beneficial preventing DR—the leading cause of blindness among adults in the United States—even in individuals with well managed T1D.
