Charles Bonnet's syndrome is characterized by the existence of visual hallucinations without psychiatric manifestations or cognitive disorder. Most patients are elderly people with severe visual problems. The objective of this paper is to describe the cases of three patients with this syndrome. ⋯ Treatment with neuroleptics or antiepileptics was effective only in one case. We conclude that it is important to know the syndrome and to differentiate it from psychiatric semiology. Deafferentation of the visual cortex could be the decisive factor in the occurrence of visual hallucinations.
