Coronation Street: What is Charles Bonnet syndrome?

Charles Bonnet syndrome causes a person whose vision has started to deteriorate to see things that aren’t real (hallucinations).

According to the NHS website, hallucinations may be simple patterns or detailed images of events, people or places. However they’re only visual and don’t involve hearing things or other sensations.

Hallucinations associated with Charles Bonnet syndrome are caused by failing eyesight and not mental health problems or dementia.

There are two types of hallucinations with the syndrome. These are simple repeated patterns or complex images of people, objects or landscapes.

Simple repeated patterns can take the form of grids, shapes or lines which can appear in bright or vivid colours.
