Visual Hallucinations in Psychologically Normal People:Charles Bonnet's Syndrome
Lancet 347:794-797, Teunisse,R.J.,et al, 1996
See this aricle in Pubmed

Article Abstract
Although diagnostic criteria demand merely"partial insight",all patients had full insight into the unreal nature of their hallucinations.Other characteristics varied.In 46(77%)patients,hallucinations lacked a personal meaning.Sensory deprivation and a low level of arousal seemed to favour the occurrence of hallucinations.CBS caused considerable distress in only 17(28%)patients.However,all patients were glad to be told that their hallucinations were not due to mental disease.The proper diagnosis had been made in only one of the 16 patients who had consulted a doctor. Although largely unrecognised in clinical practice,CBS should be considered as a diagnosis in patients who complain of hallucinations and who meet defined diagnostic criteria.There is no proven treatment,by many patients will benefit from reassurance that their hallucinations do not imply mental illness.
