Age-related macular degeneration is a condition in which there is a slow breakdown of cells in the center of the retina (the light-sensitive layers of nerve tissue at the back of the eye). This blocks vision in the center of the eye and can cause problems with activities such as reading and driving. Age-related macular degeneration is most often seen in people who are over the age of 50. Also called AMD, ARMD, and macular degeneration.

Age-related macular degeneration (AMD) is a disease that affects an individual's central vision. AMD is the most common cause of severe vision loss among people over 60. Because only the center of vision (the macula) is affected, people rarely go completely blind from this disease. However, AMD can have devastating effects, making it difficult or impossible to read, drive, or perform other daily activities that require fine, central vision.
AMD occurs when the macula, which is located in the center of the retina and provides us with sight in the center of our field of vision, begins to degenerate. With less of the macula working, central vision begins to deteriorate, while peripheral vision may stay intact.Helpful? 1 person found this helpful.
Age-related macular degeneration is an eye disease that causes blurry vision and makes it hard to read, drive, and see pictures or faces. It happens because of damage to the macula, the part of the eye that helps you see the fine detail in things that are in front of you.
There are two types of macular degeneration: wet and dry.
- In the dry form, central vision grows dimmer or more blurry as the disease progresses.
- In the wet form, symptoms appear suddenly, get worse rapidly, and often lead to severe central vision loss.
The wet form is much less common, but it is more sudden and severe.

UCLA Health answeredAge-related macular degeneration (AMD) is deterioration of the macula, which is the central part of the retina that distinguishes fine detail. It causes a gradual loss of central vision, making it difficult to see objects, and is the leading cause of vision loss in Americans age 60 or older. There are two types of AMD: dry and wet. The dry type usually starts with blurred vision, which often goes away in brighter light. The classic early symptom in wet AMD is straight lines that appear crooked.
Jeffrey Heier, MD, Ophthalmology, answeredAge-related macular degeneration (AMD) strikes at the macula, the heart of the eye's vision center. This small part of the retina (the innermost layer of the eye), which measures only about 3 by 5 millimeters (less than one-quarter-inch square) is responsible for sharp, central vision. People with AMD often develop blurred or distorted vision and cannot clearly see objects directly in front of them. Eventually they may develop a blind spot in the middle of their field of vision that increases in size as the disease progresses.
Although the disorder eventually can become debilitating, in the earliest stages of AMD there often are no warning symptoms. If the condition progresses to intermediate AMD, some people begin to notice blurring in the center of their vision. At the advanced stage, the blurred area increases, making it hard to read or even recognize people. About eight million Americans have early or intermediate AMD, and more than two million people ages 50 and older have an advanced form that is characterized by severe vision problems.Helpful? 1 person found this helpful.
Over age 60? Get screened for age-related macular degeneration (AMD), the leading cause of vision loss in people of that age group. With AMD, the most sensitive part of the retina -- the macula -- degenerates to the point that central vision is gradually lost. Picture a large smudge in the center of a movie screen.
Celeste Robb-Nicholson, Internal Medicine, answeredAmong the vision problems that plague older women, age-related macular degeneration (AMD) is perhaps the most serious. Although the chance of developing AMD is lower than the risk of cataracts (30% vs. 70% in women over 75), macular degeneration is more difficult to treat and thus a greater source of disability in older women. However, promising approaches to preventing and treating AMD are emerging.
When the macula, a collection of cells in the center of the retina, begins to deteriorate, central vision is eroded. Nine out of 10 people with AMD have the dry, or atrophic, form of this disease, which progresses slowly through early, intermediate, and advanced stages. The remaining 10% have wet AMD, which begins as the dry form and is characterized by the sudden growth of abnormal blood vessels behind the macula.
Smoking increases the risk of developing both types of AMD. Diets low in green, leafy vegetables and high in fat are also associated with AMD.
Age-related macular degeneration (AMD) is a disease of the macula, the small part of the eye’s retina that is responsible for our central vision. This condition affects both distance and close vision and can make some activities — like threading a needle or reading — very difficult or impossible. Macular degeneration is the leading cause of severe vision loss in people over the age of 50.
Many people with AMD have deposits under the retina called drusen. Drusen alone usually do not cause vision loss, but when they grow in size or number, there is an increased risk of developing advanced AMD. People at risk of developing a late stage of AMD may have a large amount of drusen or they may have abnormal blood vessels growing beneath the macula in one eye.
