Definition: Macular degeneration is an eye disease that disrupts the central, specialized part of the retina called the macula. The macula is responsible for giving us clear, sharp central vision and enables us to see things in great detail. We use our macula when we are reading printed material or looking at street signs.

Macular degeneration may affect only one eye, although it commonly affects both. Some types of macular degeneration can occur in young people; however, the main type, age-related macular degeneration (ARMD), mainly affects people 55 years of age and older.

Macular degeneration is generally painless and progresses very slowly, although in some cases it can progress rapidly and cause significant and permanent central vision loss. There is no cure for macular degeneration. Treatment is focused on preventing further vision loss.
