Eligible patients with diabetes mellitus and\u002For non-proliferative diabetic retinopathy (NPDR), who meet the inclusion and exclusion criteria, will be recruited. General and disease-related information will be collected. All eligible participants will be required to voluntarily sign an informed consent form after fully understanding and accepting the study. Successfully enrolled subjects will be randomly assigned to the Ginaton group or the conventional treatment group, and will receive the corresponding interventions as specified in the study protocol. Follow-up assessments will include blood pressure, blood glucose, glycated hemoglobin, blood lipids, hemorheological parameters, glomerular filtration rate, microalbuminuria, nerve conduction velocity by electromyography, visual acuity, wide-field fundus photography, quality of life (SF-36 questionnaire), and adverse events. The study aims to evaluate the efficacy and safety of ginkgo biloba extract tablet in preventing the development of diabetic retinopathy in patients with long-standing diabetes, as well as in treating patients with mild to moderate NPDR without concomitant diabetic macular edema (DME).",[52],"Non-proliferative Diabetic Retinopathy (NPDR)","NOT_YET_RECRUITING","2025-11-14",{"date":56,"type":57},"2025-11-19","ACTUAL",{"date":59,"type":46},"2025-11-20",{"date":61,"type":46},"2028-12-31",{"name":5,"class":6}]
