There are many forms of macular disease, including age-related macular degeneration (AMD). All macular diseases affect central vision and do not cause complete sight loss, there is always some peripheral vision remaining. You may find your central vision becomes blurry or distorted and gaps or dark spots may appear in your vision. As AMD progresses, your ability to see clearly will change.
AMD usually affects people over 60 but it can happen earlier. In the UK around 600,000 people are affected by AMD – it is the most common cause of sight loss in the developed world. About half of people affected by AMD are registered as visually impaired, although it's important to remember that no matter how advanced your macular degeneration is, you will not lose all your sight.
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.
