After observing the living conditions of the modeled mice and detecting their fasting blood glucose (FBG), it was found that the modeled mice exhibited clinically similar symptoms in patients with type I diabetes, and their FBG was larger than 16.7 mmol/L, indicating that the experimental mouse model was obtained. The mice were divided into groups. The control group was divided into negative control group (A), light positive control group (B), diabetic control group (C), and diabetes care group (D) according to different treatment methods, and the experimental group was divided into treatment group 1 (LR1), treatment group 2 (LR2) and treatment group 3 (LR3) according to different injection doses. The eyes of mice in each group were extracted and retinal tissue sections were made, and the sections were stained with HE. The retinal morphology was observed and it was found that compared with group A, the outer nucleus layer was significantly thinner in group B and C, and the group D was the thinnest. After treatment with liraglutid...
