Diabetic retinal neurodegeneration is a serious complication of diabetes mellitus,manifested by apoptosis and gliosis,and its pathogenesis is closely related to the oxidative stress induced by high glucose levels.The increase in blood glucose in the body leads to excessive production of reactive oxygen species and the downregulation of antioxidant defense signaling pathways,which leads to oxidative stress in the body,which in turn induces apoptosis,mitochondrial damage and autophagy,resulting in diabetic retinal neurodegeneration.Antioxidant stress therapy with gene therapy,flavonoids,recombinant Ad-β-catenin carriers,and autophagy inducers to exert neuroprotective effects.In the future,more clinical trials are needed to explore the effective dosage and side effects of drugs,and to develop new drugs and treatment strategies for oxidative stress to prevent and treat diabetic retinal neurodegeneration and protect retinal nerve function.
