Charles Bonnet Syndrome

Charles Bonnet syndrome is the term that is used to describe visual perceptions without physical substrate in the setting of poor ocular health. Basically, the eye that does not function well sends incomplete/inaccurate data to the brain, and the brain “conjures up” images by trying to create sensible images out of that imperfect data.

In the December 2022 issue of the journal Ophthalmology, Dr. Katrina daSilva Morgan and colleagues published an article suggesting that stimulating the brain through external electrodes can help decrease the symptoms of Charles Bonnet Syndrome. They also suggest that there are no significant side effects with this treatment, which makes this very interesting.
