Oxidative Stress in Age-Related Macular Degeneration: Nrf2 as Therapeutic Target. Along with various genetic and environmental factors that contribute to AMD, aging and age-related oxidative damage have critical involvement in AMD pathogenesis.
To this end, dietary intake of antioxidants is a proven way to scavenge free radicals and to prevent or slow AMD progression. This review focuses on AMD and highlights the pathogenic role of oxidative stress in AMD from both clinical and experimental studies.
The beneficial roles of antioxidants and dietary micronutrients in AMD are also summarized.

It Fee an imbalance between the Energy recovery systems of free radicals and radocals ability of antioxidants to neutralize them. Caffeine and reaction performance, cells produce metabolic-derived end products and generate mauclar by reducing molecular oxygen to water. During this process, small amounts of partially reduced reactive oxygen species are produced as byproducts of mitochondrial respiration. Reactive oxygen species ROS can damage the component of the cell lipid, proteins, and nucleic acid. Cells have an antioxidant system to counter the effect of ROS. In ocular tissue, metabolism occurs in the cornea, natural crystalline lens, retinal pigment epithelium. Glucose is metabolized through series of cellular cycles glycolysis, Krebs cycle, hexose monophosphate shunt, sorbitol pathway.Video

AMD Caffeine and reaction performance a degenerative disease of the andd, leading to loss of central Caffeine and reaction performance. Indeed it is the foremost cause of blindness in the developed world. Although AMD is a complex multifactorial disease, oxidative stress is likely to be a key instigator in its pathogenesis. Evidence for this includes studies that demonstrate the presence of lower systemic antioxidant levels in association with AMD, although systemic levels of reactive oxygen species are not correlated. There is also some evidence that sequence variations in antioxidant genes may be associated with AMD, especially in animal models.
