Abstract:
Dry eye disease is a multifactorial chronic ocular surface disorder that is challenging to manage because its pathogenesis is not well understood. The gut-eye axis theory provides insights into its pathogenesis to guide prevention and treatment. Intestinal flora dysbiosis induces dry eye disease through complex mechanisms involving inflammation, ocular surface microbiota, nerve damage, and microbial metabolites. This article reviews the immunometabolic regulation of the gut-eye axis and summarizes gut flora-targeted interventions(fecal microbiota transplantation, probiotic supplementation, and dietary modification)to provide a theoretical basis for dry eye disease prevention and treatment.
