Zusammenfassung

Das Charles Bonnet Syndrom (CBS) wird definiert als das Auftreten von visuellen Halluzinationen (VH) ohne psychopathologische Erkrankungen. Von dieser Erkrankung sind hauptsächlich ältere Patientinnen und Patienten betroffen, die aufgrund ihres geringen Visus bedingt durch ophthalmologische Pathologien (meist durch die altersbedingte Makuladegneration – AMD) VH erleiden. Zur Prävalenz des CBS im europäischen Raum können viele unterschiedliche Ergebnisse gefunden werden. Mehr über diese Erkrankung zu lernen ist essentiell, um gegebenenfalls die Symptome zu erkennen, richtig zu deuten und betroffenen Patienten adäquate Information und Therapie zu kommen zu lassen. Genaue und einheitliche diagnostische Kriterien für ein CBS sind die Grundlage weiterer Studien.

Summary

A 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 often associated with the syndrome are age-related macular degeneration (AMD), cataract and glaucoma. Existing data on the syndrome’s prevalence in Europe reveal diverse results. It is essential for people involved with patients suffering from severe vision loss to learn more about the Charles Bonnet Syndrome. This will make it easier to identify and interpret symptoms correctly and might also lead to a more adequate information and therapy for affected patients. For further studies precise and standardised diagnostic criteria should be defined.
