    摘要: The present invention provides methods and compositions for alleviating and preventing age-associated visual degeneration in a mammal, comprising administrating to the mammal in need thereof an effective amount of L-Ergothioneine, an analog or derivative thereof, or a pharmaceutically acceptable salt, acid, ester, polymer, analog or derivative thereof, as an active ingredient. In particular, the administration of L-Ergothioneine is capable of controlling subretinal choroidal neovascularization (CNV) level in the mammal's retina; activating Nrf2-mediated antioxidant genes to scavenge chronic reactive oxygen species and decrease vascular endothelial growth factor (VEGF) level in the mammal's retinal pigment epithelium (RPE); activating Nrf2-mediated antioxidant genes by lowering the damage induced by oxidative stress (OS) in the mammal's RPE; and/or inhibiting oxidation-induced epithelial-to-mesenchymal transition (EMT) to prevent epithelial fibrosis in RPE in mammals' RPE.
