This degenerative disease affects central vision and is the leading cause of vision loss in older Americans.
What is macular degeneration?
Macular degeneration, or age-related macular degeneration (AMD), is a leading cause of vision loss in Americans 60 and older. It is a disease that destroys your sharp, central vision. You need central vision to see objects clearly and to do tasks such as reading and driving.
Macular degeneration affects the macula, the part of the eye that allows you to see fine detail. It does not hurt, but it causes cells in the macula to die.
There are two types of macular degeneration: wet and dry. Wet macular degeneration happens when abnormal blood vessels grow under the macula. They often leak blood and fluid. Wet macular degeneration damages the macula quickly. Blurred vision is a common early symptom. Dry macular degeneration happens when the light-sensitive cells in the macula slowly break down. You gradually lose your central vision. A common early symptom is that straight lines appear crooked.
Regular comprehensive eye exams can detect macular degeneration before the disease causes vision loss. Treatment can slow vision loss. It does not restore vision.
