What you should know about macular degeneration

Also known as "age-related" macular degeneration (AMD), is an eye disorder commonly associated with aging. It causes the gradual loss of clear central vision. The macula is the tissue at the center of the retina on the inside surface of the back of your eye. The macula is necessary for reading and fine vision. When the macula deteriorates, it causes symptoms such as blurred central vision or a blind spot in the center of your vision.

Two types of AMD — dry and wet

Dry AMD is, by far, the more common type. It occurs when light-sensitive tissue in the macula grow thin and break down over time. The loss of tissue gradually causes blurred central vision. Dry AMD has three stages — early, intermediate and advanced. Dry macular degeneration may worsen your quality of life by causing blurred central vision or a blind spot in your central vision. You need clear central vision for many tasks, such as reading, driving and recognizing faces.

Wet AMD causes the growth of abnormal blood vessels under the retina. This results in leaking blood or fluid, which causes damage to the macula. Wet AMD nearly always starts out as dry AMD. And it can cause rapid central vision loss.

AMD typically affects people with light-colored eyes. Light and dark eyes filter light differently. Researchers and clinicians believe that people with dark colored eyes are much less likely to contract AMD because darker pigment offers better protection for their retinas.
