What is Charles Bonnet Syndrome?

Charles Bonnet syndrome is a visual condition that causes hallucinations. These hallucinations are brought on by the brain’s adjustment to loss of vision. This condition is most common in elderly patients that have other eye related conditions such as macular degeneration.

This syndrome is a very common condition; but a lot of people do not know that they have it. Around 50% of patients with vision loss will experience Charles Bonnet syndrome.

Research has shown that a lot of people will not go to their doctors about the hallucinations as they are worried that they may be related to mental health problems rather than vision problems. As your brain gets used to the changes in vision, the hallucinations should stop/ become less noticeable.

As mentioned before the cause of Charles Bonnet syndrome is thought to be linked to a problem with vision loss. Although the exact cause and full understanding of the condition is still unknown.

Here is a list of the most common associated signs and symptoms:

• Severe vision loss
• Visual hallucinations
• Inability to control your hallucinations

How do you know if you have Charles Bonnet syndrome and what do the hallucinations look or feel like?
