The Charles Bonnet syndrome is characterized by the presence of complex visual hallucinations among elderly patients with ophthalmic disease previously free of any psychiatric disorder. It has long been considered rare because of the reluctance of patients for fear of being thought mentally ill.
The objective of this work is to recognize the clinical characteristics of Charles Bonnet syndrome, allowing early detection and adequate care, through the presentation of two cases.
The authors report two cases of elderly, free of any dementia, patients, with the result of an intervention on cataract complicated by a bilateral blindness. Charles Bonnet syndrome is revealed by complex visual and stereotyped hallucinations.
These hallucinations exacerbated at night, disturbing the sleep of these patients.
Only when the insomnia was associated with anxiety agitation, their respective families decided to make the patients consult the psychiatrist.
The evolution under antipsychotic and antidepressant drugs was only partial.
