What is age-related macular degeneration (AMD)?
Age-related macular degeneration (AMD) is a disease that causes blurring of your central vision. The blurring happens because of damage to the macula, a small area at the back of the eye. The macula helps you see the fine detail in things that your eyes are focusing on.
Macular degeneration makes it harder to do things that require sharp central vision, like reading, driving, and recognizing faces. It does not affect side vision, so it does not lead to complete blindness.
There are two types of macular degeneration—wet and dry. The dry form is by far the most common type. The wet form is much less common, but it happens more quickly and is more severe.
