Charles Bonnet Syndrome (CBS) is defined by the occurence of visual hallucinations (VH) in the absence of any mental disorder. Elderly patients with reduced visual acuity due to ophthalmic diseases are most affected. Conditions are often associated with the syndrome of age-related macular degeneration, cataract or glaucoma. Existing data on the syndrome's prevalence in Europe reveal diverse results. Aim of this study was to assess the prevalence of CBS in patients with low visual acuity and to evaluate, if an additional therapeutic interview with and treatment by a psychiatrist is beneficial.
