Age-related macular degeneration (AMD)
View original article on NHS Choices
- Age-related macular degeneration (AMD) is a common condition that affects the middle part of your vision. It usually first affects people in their 50s and 60s.
- It does not cause total blindness. But it can make everyday activities like reading and recognising faces difficult.
- Without treatment, your vision may get worse. This can happen gradually over several years ("dry AMD"), or quickly over a few weeks or months ("wet AMD").
- The exact cause is unknown. It's been linked to smoking, high blood pressure, being overweight and having a family history of AMD.
