概要	Background: The aim of this study is to investigate the effect of glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RA), liraglutide, against diabetic retinal edema using an animal model of type 2 diabetes. Methods: Male spontaneously diabetic torii (SDT) fatty rats at 8 weeks of age were randomly assigned to three groups; the liraglutide group has been subcutaneous injected liraglutide for 8 weeks. Other group was provided both insulin against hyperglycemia and hydralazine against hypertension for matching both levels of blood glucose and blood pressure with the liraglutide group. A control group was injected only a vehicle. Results: Control group exhibited hyperglycemia and hypertension, whereas two treatment groups similarly reduced both blood glucose and blood pressure levels. While retinal thickening for the retinal edema was found in control group, the degree was significantly prevented in the liraglutide group. Furthermore, the effect was also brought by the treatments of both insulin and hydralazine. Conclusions: Liraglutide prevented the retinal edema characterized in the early phase of diabetic retinopathy via reduction of both blood glucose and blood pressure levels.
