Age-related macular degeneration (AMD) is the biggest cause of sight loss in the UK, affecting over 600,000 people.
There are many forms of macular disease, but AMD is the most common, usually affecting people over the age of 50.
AMD affects central vision - it may become blurry or distorted and gaps or dark spots may appear. As AMD progresses, your ability to see clearly will change. However, it's important to remember that no matter how advanced your macular degeneration is, you will not lose all your sight as there is always some peripheral vision remaining.
The older we are the greater our risk of developing AMD. Around one in every 200 people has AMD at 60. However, by the age of 90 it affects one person in five. We are all living longer so the number of people affected is increasing. There are two forms of AMD – dry and wet.
