ARMD: age related macular degeneration
Macular degeneration is the leading cause of central vision loss among older people. It results from changes to the macula which is the portion of the retina responsible for clear, sharp vision. The macula is many times more sensitive than the rest of the retina and without a healthy macula, seeing detail or vivid color is not possible.
There are several causes for macular degeneration. In one type, the tissue of the macula becomes thin and stops working well. This type is thought to be a part of the natural aging process in some people.
In another, fluids from newly formed blood vessels leak into the eye and cause vision loss. If detected early, this condition can be treated with laser therapy, but early detection and prompt treatment is vital in limiting damage.
Macular degeneration develops differently in each person, so the symptoms may vary. Unfortunately, there is no way to restore the central vision damaged by macular degeneration. Therefore, early detection of macular degeneration is the most important factor in determining if you can be treated effectively.
