Charles Bonnet syndrome (CBS) was first described by Swiss philosopher Charles Bonnet in 1760. The defining characteristics of the syndrome include visual impairment, complex visual hallucinations, preservation of mental competence, and insight. The syndrome is an infrequently diagnosed but rather common cause of complex visual hallucinations. Its prevalence in patients with visual impairment varies from 10% to 15%, and it occurs most commonly in elderly people.
