Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes, which seriously threatens the vision of patients. The pathogenesis of DR is complex, and the main treatment methods for DR Include: panretinal laser photocoagulation therapy, pars plana vitrectomy and intravitreal injection of drugs, etc. However, all the treatment methods have certain limitations. In recent years, progress has been made in the fields of intravitreal injection of anti-vascular endothelial growth factor drugs, anti-inflammatory therapy, anti-oxidative stress injury drugs, neuroprotective drugs, gene therapy and stem cell therapy. DR treatment drugs are loaded with nanoparticles, hydrogels and photosensitive materials, which can be continuously and efficiently released in the eye, extending the time interval of administration. In the future, personalized and precise treatment based on biomarker detection can develop more accurate treatment plans for patients and improve curative effect.
