Charles bonnet syndrome

Charles Bonnet Syndrome (CBS) or visual release hallucinations are a type of psychophysical visual disturbance and the experience of complex visual hallucinations (VHs) in a person with partial or severe blindness. We present a case of 73-year-old blind male, who lost his vision due to glaucoma, presented with a history of complex VHs. The investigations for alternative pathological causes of VHs were negative and therefore, the etiology of hallucinations was attributed to CBS. Excellent response to low-dose olanzapine was seen, with complete remission by the end of 5th week after starting olanzapine.
