Diabetic retinopathy (DR) is one of the most frequent and serious retinal microvascular complications of diabetic mellitus (DM), which belongs to the category of intraocular disturbance diseases of traditional Chinese medicine. Astragaloside Ⅳ (AS-Ⅳ), the main active component of Huangqi (Astragali Radix), integrates multiple pharmacological targets that align with the complex pathogenesis of DR. For the past few years, numerous studies have focused on the impact of AS-Ⅳ on DR, confirming its effects through various mechanisms such as hypoglycemic effect, anti-oxidative stress damage, inhibition of vascular endothelial growth factor (VEGF), anti-apoptosis of retinal cells, suppression of inflammatory responses, and inhibition of ferroptosis, thereby obstructing the occurrence and progression of DR through multiple pathways and targets. This paper mainly reviewed the research progress of AS-Ⅳ on the treatment of DR in order to provide reference for its further development and utilization and clinical application.
