Dry age-related macular degeneration (AMD) is a slow deterioration of the cells of the macula, as the retinal cells die off and are not renewed often over many years. The term dry does not mean the person has dry eyes, just that the condition is not wet AMD. The progression of dry AMD varies, but in most people it develops over many months or years. People often carry on as normal for some time.
The macula is part of the retina at the back of the eye. It is only about 5mm across but is responsible for all of our central vision, most of our colour vision and the fine detail of what we see.
