Quetiapine Therapy for Visual Hallucinations Caused by Charles Bonnet Syndrome / 대한정신약물학회지

The case of a 77-year-old man with Charles Bonnet syndrome was presented. This patient lost his vision due to glaucoma, and he subsequently developed complex visual hallucinations. No other psychotic symptoms (e.g., delusions, perceptual disturbances) and no evidence of cognitive impairment or neurological diseases were reported. The visual hallucinations disappeared after treatment with quetiapine, an atypical antipsychotic, without any side effects. The visual hallucinations reappeared after quetiapine was discontinued. Treatment with a small dose of quetiapine has been maintained to prevent the exacerbation of symptoms.
