Seeing Things
It was a pleasure to attend the first day of the Seeing Things interactive art exhibition, which is taking place at the lovely Forum in Norwich over the next two weeks.
Charles Bonnet Syndrome is a type of visual hallucination which people can experience after sight loss. In comparison with other types of hallucination, those who experience these know that they are just a creation of the brain as a reaction to visual loss.

The Art of Charles Bonnet
This art exhibition, set up by the NNAB, features art from people who suffer from the syndrome, as well as other visual artists who have been inspired from speaking to those who experience these vivid hallucinations, which have their own unique attributes in comparison with other types of hallucinations.

Experiences
Dominic Ffytche, a world expert in the condition, gave a fantastic lecture about the Syndrome, and it was indeed fascinating to listen to the experienced of sufferers from the condition. The audience comprised of people who suffered from the condition, people who had not previously heard of the syndrome and clinicians, such as myself, who are aware about the condition but want to understand more and gain perspective.
I was particularly intrigued by the number of people who experience hallucinations of old period clothing from different eras, which seems to be a consistent feature of the syndrome. Interestingly, even when the syndrome was first described 250 years ago - the literature describes sufferers talking about people wearing period dress of the time. Perhaps 18th century formal-wear has a hallucinatory quality to it?

Gaps
Even though Charles Bonnet Syndrome was first described 250 years ago, by a Swiss philosopher who was writing about his grandfather's experiences having lost his sight to cataracts, we still do not know why exactly it happens. Certainly, we suspect that the brain fills in the gaps generated from visual loss by producing new fantastic pictures or old images which it might have stored. For many people, these hallucinations are not a problem but for some they can, understandably, be distressing. Certainly, it helps to understand these hallucinations and it is useful for both sufferers, the public and clinicians (such as yours truly) to be aware and understand this fascinating condition.

To this end, it is fantastic to have an art exhibition which both raises awareness and bewitches us, humbling us as clinicians into realising there is still so much about the eyes and the brain that we don't yet understand.
