Dry macular degeneration is a chronic eye disease that causes vision loss in the center of your field of vision. Dry macular degeneration is marked by deterioration of the macula (MAK-u-luh), which is in the center of the retina — the layer of tissue on the inside back wall of your eyeball.
Dry macular degeneration is one of two types of age-related macular degeneration. The other type — wet macular degeneration — is characterized by swelling caused by leaky blood vessels in the back of the eye. Dry macular degeneration isn't associated with swelling and is the more-common form of the disease.
Dry macular degeneration doesn't cause total blindness, but it worsens your quality of life by blurring or causing a blind spot in your central vision. Clear central vision is necessary for reading, driving and recognizing faces.
