Charles Bonnet syndrome (CBS) is diagnosed when a visually impaired patient without any mental disorder develops visual hallucinations. A survey of patients in a National Leprosarium revealed that the point prevalence of CBS in leprosy was 0.4%. This prevalence appears to be high, as few cases with CBS have been reported. The semeiology of visual hallucinations was typical of CBS. However, the clinical features were different from previous reported cases because of the history of leprosy and associated multi-sensory loss. Patients with leprosy appear to be at increased risk for CBS, due to frequent eye complications combined with sensory loss, ageing, and intact intellectual functions.
查尔斯·博内综合征（CBS）是指在没有任何精神障碍的视力受损患者中出现视幻觉时所做出的诊断。一项对某国家麻风病院患者的调查显示，麻风病患者中CBS的点患病率为0.4%。这一患病率似乎较高，因为此前报道的CBS病例较少。视幻觉的症状学表现为CBS的典型症状。然而，由于麻风病史以及相关的多感官丧失，其临床特征与先前报道的病例有所不同。由于频繁的眼部并发症、感觉丧失、衰老以及智力功能完好，麻风病患者似乎患CBS的风险增加。
