Age-related macular degeneration 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.
You may have either type in just one eye, but over time you may get it in the other eye too.
What causes macular degeneration?
Macular degeneration is the result of damage to the nerve cells in the macula. The process that leads to this damage is different for each type.
