Abstract:The Charles Bonnet syndrome (CBS) is characterized by the presence of complex visual hallucinations in psychologically normal people. The prevalence of CBS has been reported to vary from 0.4% to 40% in different ophthalmological populations. Little is known about its etiology and pathogenesis. The clinical characteristics of CBS show rich variety. There is no effective pharmacotherapy for CBS. Timely diagnosis and explanation, along with reassurance about the relatively benign nature of the condition, provided immeasurable relief. Further exploration of treatment options will be necessary in the future. This paper reviews recent published medical reports on CBS.
