Oxidative stress in AMD. ROS are increased in RPE and photoreceptors since the exposure of environmental risk factors in the early stage of AMD. ROS lead to the deposits of lipid substances, phagocytosis disability, and cell injury in protein, lipids, and DNA, until cell death. AMD: age-related macular degeneration; ROS: reactive oxygen species; RPE: retinal pigmented epithelium.
