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. This treatment needs much more research before scientists can know for sure if it is helpful. Almost all people with macular degeneration lose their central vision but retain their peripheral or side vision.
