Charles Bonnet综合征（CBS）的主要特征为发生于非精神异常患者的复杂性幻视，患病率约为0.4%~40％。其病因学尚不明确，临床特征亦复杂多样，目前尚无有效药物治疗。及时诊断、合理解释将有助于缓解患者情绪。治疗方案仍有待进一步研究。本文将近年来有关CBS的研究进行综述。

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.
