Macular degeneration results from damage to the macula, the part of the eye responsible for central vision and the ability to see fine details clearly.1 Most cases of macular degeneration occur as part of the aging process and are known as age-related macular degeneration (AMD).2 AMD is a progressive retinal disease, usually occurring at age 55 years or older, with multiple environmental and genetic risk factors.3
