Age-related macular degeneration (AMD) is an eye condition affecting the macula ,part of the retina,at the back of the eye.

AMD causes problems with central vision but doesn’t lead to total sight loss and is not painful. It affects the vision used looking directly at something, for example reading, looking at photos or watching television.

AMD may make this central vision distorted or blurry and over a period of time it may cause a blank patch in the  centre of vision. Age-related macular degeneration is a deterioration or breakdown of the eye’s macula. The macula is the light-sensitive lining the back of the eye and is used to see fine details clearly

The macula only makes up a small part of the retina yet is much more sensitive to detail than the rest of it which is called the peripheral retina. The macula is what allows us to thread a needle, read small print, and read street signs. The peripheral retina gives you side (or peripheral) vision. If someone is standing off to one side of your vision, your peripheral retina helps you know that person is there by allowing you to see their general shape.

Many older people develop macular degeneration as part of the body’s natural aging process. There are different kinds of macular problems, but the most common is age-related macular degeneration.

With macular degeneration symptoms such as blurriness, dark areas or distortion in your central vision, and perhaps permanent loss of your central vision. It usually does not affect your side, or peripheral vision. With advanced macular degeneration someone may be able to see the outline of a clock but not the hands to tell the time.
It is caused by the formation of deposits called drusen .
People with more advanced cases of macular degeneration can learn to use their  peripheral vision.
 which causes a gradual loss of central vision. About 10 percent of people who have macular degeneration have the wet form, but it can cause more damage to your central or detail vision than the dry form.
