Glucagon-Like Peptide-1 Receptor Agonists are Not Associated with an Increased Risk of Progressing to Vision-Threatening Diabetic Retinopathy

PURPOSE: Glucagon-like peptide-1 receptor agonists (GLP-1RA) are used to treat type 2 diabetes mellitus (DM) by augmenting insulin release and sensitivity. We assessed the overall risk for development of vision-threatening diabetic retinopathy (VTDR), proliferative diabetic retinopathy (PDR), and diabetic macular edema (DME), among GLP-1RA users. METHODS: A retrospective cohort of patients with NPDR newly started on a GLP-1RA from a national insurance claims database was compared to a cohort of patients treated with other oral anti-diabetic agents and matched for age, sex, race, index year, and number of active diabetic medications. Exclusions occurred for < 2 years in the database before diagnosis; prior diagnoses of PDR, DME, vitreous hemorrhage, and/or other retinal vascular diseases; and prior intraocular treatment for VTDR. RESULTS: = 0.20). CONCLUSION: We found no difference in the risk for vision-threatening diabetic retinopathy, nor for its component diseases, DME or PDR, with GLP-1RA use compared to other oral anti-hyperglycemic agents in patients with NPDR.
