Glutathione and a Pool of Metabolites Partly Related to Oxidative Stress Are Associated with Low and High Myopia in an Altered Bioenergetic Environment

Autor: Salvador Mérida, Amparo Návea, Carmen Desco, Bernardo Celda, Mercedes Pardo-Tendero, José Manuel Morales-Tatay, Francisco Bosch-Morell

Publikováno v: Antioxidants, Vol 13, Iss 5, p 539 (2024)

Oxidative stress forms part of the molecular basis contributing to the development and manifestation of myopia, a refractive error with associated pathology that is increasingly prevalent worldwide and that subsequently leads to an upsurge in degener
