 This study found that the incidence of age-related macular degeneration, AMD, increases with age, especially after the age of 55. The researchers also identified certain risk factors associated with the development of late AMD, such as having early AMD and being a smoker. This information can be used to better understand the disease and its progression, as well as to develop prevention strategies. This article was authored by Annette Peters, Robert P.
