Antioxidants & Age-Related Eye Disease
Cataracts and age-related macular degeneration (AMD) are the leading causes of visual impairment and acquired blindness in the U.S. These diseases affect millions of aging Americans.AMD is the leading cause of blindness in people over age 55 in the Western world. As the population ages, AMD is expected to triple by 2025.Cataract extractions are the most common surgical procedure performed in the U.S., accounting for more than 2 million procedures a year.
