There are two types of age-related macular degeneration (AMD). Wet AMD and dry AMD.
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.
There is no medical treatment for dry AMD but research is going on around the world.
Around 10-15% of people with dry AMD go on to develop wet AMD. If you have dry AMD and notice a sudden change in your vision, it is important that you contact your optometrist, or hospital eye specialist, urgently. If you have AMD in one eye, the other eye may also be affected within a few years.
