Abstract
Iron is essential for normal cellular function, however, excessive accumulation of iron in neural tissue has been implicated in both cortical and retinal diseases. The exact role of iron in the pathogenesis of neurodegenerative disorders remains incompletely understood. However, iron-induced damage to the brain and retina is often attributed to the redox ability of iron to generate dangerous free radicals, which exacerbates local oxidative stress and neuronal damage. Iron chelators are compounds designed to scavenge labile iron, aiding to regulate iron bioavailability. Recently there has been growing interest in the application of chelating agents for treatment of diseases including neurodegenerative conditions, characterized by increased oxidative stress. This article reviews both clinical and preclinical evidence relating to the effectiveness of iron chelation therapy in conditions of iron dyshomeostasis linked to neurodegeneration in the brain and retina. The limitations as well as future opportunities iron chelation therapy are discussed.
