Charles Bonnet syndrome, visual hallucinations, visual impairment
Summary of the research project
Charles Bonnet syndrome (CBS) is the experience of visual hallucinations by people with visual impairment. CBS hallucinations vary widely between individuals, from simple geometric shapes and patterns to complete people, animals or entire scenes. CBS is most prevalent in those with recent acquired visual loss, but can vary in duration and frequency, and persist for many years. For many people, once they are aware of the normality of CBS, the hallucinations are perceived as neutral or even pleasant. However, for approximately one third of those experiencing CBS, the hallucinations have a ‘negative impact’, being frightening or disturbing to the person, and potentially impact on quality of life.
This project will evaluate the emotional impact of CBS, particularly for those with negative impact CBS, in order to guide better practice in identifying, managing and treating this condition. The project will involve development of skills in both qualitative and quantitative research methodologies, including interviews and their analysis and development and validation of a patient reported outcome measure. The software and facilities required for the project are available. Participants will be recruited in collaboration with the CBS-specific campaign ‘Esme’s Umbrella’.
