Research progress of oxidative stress in diabetic keratopathy

Abstract

It is estimated that currently, about 46%-64% of patients with diabetes mellitus(DM)suffer from diabetic keratopathy(DK). With the increasing prevalence of DM, DK has gradually been concerned by ophthalmologists. Nevertheless, its pathogenesis is not yet clear. Oxidative stress is a pathological process that causes excessive production of reactive oxygen species(ROS)and reactive nitrogen species(RNS)in the body, which damages tissues and cells. It participates in the occurrence and development of many diseases, including the ocular complications of DM. This study aims to review the research progress of oxidative stress in the pathogenesis and the treatment of diabetic corneal lesions, thus providing references for clinical diagnosis and treatment of DK.
