title: Nutritional Interventions against Age-Related Macular Degeneration.
abstract: Age-related macular degeneration (AMD) is the leading cause of irreversible visual loss in the developed world. This disease of the elderly robs them of central vision in one or both eyes leading to a devastating loss of the ability to drive, read, and recognize faces. In recent years, a number of novel treatments for the neovascular form of AMD (also known as "wet" or exudative AMD) have been introduced, and for the first time, the relentless downhill course of vision loss experienced by the majority of patients with this particularly malignant variant of AMD has been transformed to the stabilization and even improvement of vision in at least two-thirds of patients. Likewise, the slower, more insidious form of AMD known as dry AMD which leads to geographic atrophy of the macula has become the focus of pharmaceutical firms' efforts for intervention. Unfortunately, all of these novel treatments have limitations, and they tend to be very expensive. Thus, prevention of AMD is of paramount importance to reduce the healthcare burden of this blinding disorder. Accumulating evidence suggests that encouragement of increased consumption of fruits and vegetables rich in the xanthophyll carotenoids lutein and zeaxanthin is a simple, cost effective public health intervention that might help to decrease the incidence of AMD. In this review article, the scientific underpinnings for these nutritional recommendations will be surveyed.
