Many older people develop macular degeneration as part of the body's natural
aging process. There are different kinds of macular problems, but the most
common is age-related macular degeneration.
With macular degeneration, you may have symptoms such as blurriness, dark areas
or distortion in your central vision, and perhaps permanent loss of your central
vision. It usually does not affect your side, or peripheral vision.
When macular degeneration does lead to loss of vision, it usually begins in just
one eye, though it may affect the other eye later. Many people are not aware that
they have macular degeneration until they have a noticeable vision problem or
until it is detected during an eye examination.
