The Charles Bonnet syndrome: a review

J Nerv Ment Dis. 1997 Mar;185(3):195-200. doi: 10.1097/00005053-199703000-00009.


The Charles Bonnet syndrome (CBS) derives from complex visual hallucinations. Neurologists, ophthalmologists, and psychiatrists have studied this entity for many years. Despite interest in CBS recently in contemporary American medical literature, investigators have not agreed upon a universal definition of this entity. This article reviews the current literature on CBS and related phenomena, offers specific criteria to define this syndrome, and suggests future work in this area.
