Age-Related Macular Degeneration
What is ARMD?
Macular degeneration is the leading cause of central vision loss among older people. It results from changes to the macula, a portion of the retina responsible for clear, sharp vision located on the inside back wall of the eye.
What are the causes of ARMD?
1. There is reduced blood circulation to the tissue of the macula which is thought to be a part of the natural aging process in some people.
2. Fluids from newly formed fragile blood vessels leak into the eye and cause vision loss.
What are the symptoms of ARMD?
1. A gradual loss of ability to see objects clearly.
2. Distorted vision. Objects appear to be wrong size or shape or straight lines appear wavy or crooked.
3. A gradual loss of clear color vision.
4. A dark or empty area appearing in the center of vision.

Treatment of ARMD
Some studies show that vitamin and mineral supplements may help to slow any progressive vision loss. Some ARMD can be treated with laser therapy. Since ARMD does not damage side vision, low vision aids such as telescopic and microscopic special lenses, magnifying glasses and electronic magnifiers for close work can be prescribed to help make the most of remaining vision. Once the macula is damaged, there is no way to restore the central vision. Therefore, early detection of ARMD is the most important factor in determining if you can be treated effectively.
