Abstract:
Objective To analyze the related factors of retinopathy in elderly patients with type 2 diabetes mellitus (T2DM) and explore the discriminant efficiency. Methods A retrospective analysis was conducted on 314 elderly patients with T2DM who were treated in Beijing Aerospace General Hospital between April 2022 and April 2025. The related factors of retinopathy in elderly patients with T2DM were explored by logistic regression analysis. ROC curve was drawn to analyze the discriminant efficiency of related factors. Results Compared with the patients in the non-concurrent group, the patients in the concurrent group had a longer course of diabetes mellitus, a higher level of glycosylated hemoglobin (HbA1c), and higher proportions of diabetic peripheral neuropathy, hypertension history, high myopia history and smoking history (P<0.05). After logistic regression analysis, the course of diabetes mellitus, HbA1c, diabetic peripheral neuropathy, history of hypertension and history of high myopia were found to be related factors of retinopathy in elderly patients with T2DM (P<0.05). Based on the above related factors, a model was established for ROC curve analysis, and it was found that the area under the curve was 0.935, with sensitivity, specificity, and 95%CI being 0.867, 0.916, and 0.890-0.979, respectively. Conclusion Course of diabetes mellitus, HbA1c, diabetic peripheral neuropathy, history of hypertension, and history of high myopia are related factors of retinopathy in elderly patients with T2DM. These related factors demonstrate good discriminant efficiency on retinopathy in elderly patients with T2DM.
