What is Charles Bonnet syndrome?

Charles Bonnet syndrome (CBS) is a common condition among people who have lost their sight. It causes people who have lost a lot of vision to see things that aren't really there, known as visual hallucinations.

CBS is more common in people who have an eye condition such as age-related macular degeneration, cataracts, glaucoma or diabetic eye disease. Many of these conditions are more common in older people so many people who have CBS are also older. However, CBS can affect anyone of any age, including children.

More information can be found on our Charles Bonnet Syndrome web page.

We also have a Charles Bonnet syndrome leaflet, part of our Understanding series:
