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.
