For example, you could see a clock but not be able to tell what time it is. Macular degeneration alone does not result in total blindness. Most people continue to have some useful vision and are able to take care of themselves. Many older people develop macular degeneration as part of the body's natural aging process. It is caused by aging and thinning of the tissues of the macula.
Vision loss is usually gradual.
It results when abnormal blood vessels form at the back of the eye. These new blood vessels leak fluid or blood and blur central vision. Vision loss may be rapid and severe. Despite ongoing medical research, there is no cure yet for the condition. Some doctors believe that nutritional supplements may slow macular degeneration, although this has not yet been proven.
