Understanding Charles Bonnet Syndrome: A Hidden Challenge for the Visually Impaired
3/8/2026, 7:58:23 AM
Overview of Charles Bonnet Syndrome
Charles Bonnet Syndrome (CBS) is a condition characterized by visual hallucinations in individuals who have experienced sight loss. Patients like Alex Patterson and Elaine Orwin describe vivid, often alarming visions, such as insects on food or even a tiger walking down Royal Avenue in Belfast. These hallucinations are not indicative of mental health issues but rather a response from the brain attempting to compensate for lost visual input. Professor Tunde Peto, a Clinical Ophthalmology expert at Queen's University Belfast, explains that the brain generates images to fill in gaps caused by sight loss, leading to these hallucinations.
Personal Experiences and Coping Mechanisms
Elaine Orwin, who began losing her sight at the age of four, experienced her first hallucinations in childhood but was not diagnosed until her 30s. She recalls episodes triggered by stress or fatigue, where dark clouds would descend, affecting her remaining peripheral vision. Alex Patterson, who has been severely sight impaired for 15 years, has developed coping strategies, including techniques like blinking and looking away, as well as relying on his guide dog, Angus, to help distinguish between reality and hallucinations.
Both Patterson and Orwin emphasize the importance of understanding CBS, as many individuals remain undiagnosed and may mistakenly believe they are experiencing dementia. Orwin notes that sharing experiences in support groups has been beneficial, helping others recognize their symptoms and seek help.
The Need for Awareness and Diagnosis
Despite the prevalence of CBS, with research suggesting that approximately one in five adults experiencing sight loss develop the condition, it remains under-reported and under-diagnosed in the UK. The Royal National Institute of Blind People (RNIB) estimates that at least one million adults in the UK are living with CBS, yet specific statistics for Northern Ireland are lacking.
Professor Peto highlights that many patients do not report their symptoms, and discovering that CBS is a recognized condition often brings relief. She stresses the importance of raising awareness, especially given the ageing population, to ensure that more individuals understand and seek help for their symptoms.
Upcoming Awareness Initiatives
To address the lack of awareness surrounding CBS, an event is scheduled at Stormont, where patients, healthcare professionals, and Members of the Legislative Assembly (MLAs) will gather to discuss the condition and its implications. This initiative aims to foster dialogue and promote understanding of CBS, encouraging those affected to come forward and seek support.
Verbatim Quotes
- “If Angus doesn't flinch when we're out walking and nothing bothers him, I know I'm just having an episode and I trust him so I walk on.” — Alex Patterson, CBS Patient
- “It might be frightening to start with, but it is practically never threatening,” — Professor Tunde Peto, Clinical Ophthalmology Expert
- “Now I know and acknowledge what it is, it makes it much easier and that's why I'm hoping other people who are suffering in silence will come forward.” — Elaine Orwin, CBS Patient
Conclusion
Charles Bonnet Syndrome poses significant challenges for those with sight loss, yet it remains largely misunderstood. Increased awareness and understanding are crucial for encouraging individuals to seek diagnosis and support, ultimately improving their quality of life.
