What is age-related macular degeneration?

Normal Vision

Macular Degeneration

Age-related macular degeneration is a condition that is caused by damage to the delicate cells of the macular. We do not know why this is, although it tends to happen, as people get older.

Because macular degeneration is an age-related process it usually involves both eyes though they may not be affected at the same time. With many people the visual cells simply cease to function. Macular degeneration is not painful, and never leads to total blindness. It is the most common cause of low vision in people over 60 but never leads to complete sight loss because it is only the central vision that is affected. Macular degeneration never affects the outer edges of the eye. This means that almost everyone with macular degeneration will have enough side vision to get around and retain his or her independence.

What are the symptoms?

In the early stages your central vision may be blurred or distorted with things looking an unusual size or shape. This may happen quickly or develop over several months. You may be very sensitive to light or actually see lights that are not there. This may cause some discomfort occasionally but otherwise macular degeneration is not painful.
