However, it does not describe how to either counter the ongoing hallucinations or whether to cross stimulate with alternative or logical thinking, games etc. My mother is 97 yr with macular degeneration & cataracts. She recently went from very lucid to the CBS syndrome described above. I would appreciate further suggestions. Regards, Judith Your article was well done.

The literature on CBS suggests that the eyes closed or eyes open condition stops the illusory percepts of CBS only in a minority of cases. So it is apparently not just a complex "modulation" of existing/remaining visual input from the eyes. See for instance Teunisse R.J., Craysberg J.R., Hoefugels WH., Verboek A.I., Zitman F.G. (1996), Visual hallucinations in psychologically normal people: Charles Bonnet syndrome, Lancet 347: 794-797. Hi Tony,

A little help with one question would be appreciated though. Since light does enter the eye, would it be more accurate to describe this Charles Bonnett Syndrome as an illusion ( a misperception of external stimuli), rather than a hullucination (perception caused in the absence of stimuli). Thanks for the greatt read. What an enjoyable article. A little help with one question would be appreciated though.

Apart from "treating" or "dealing with" CBS, one can also conjecture about binding CBS to sensory substitution, like I proposed at <a href="http://www.seeingwithsound.com/imagery.htm" title="Sound-Induced Mental Imagery for the Blind" rel="nofollow">Sound-Induced Mental Imagery for the Blind</a> After all, realistic visual hallucinations with the visual content tightly bound to live but crossmodally encoded camera views would be very much like... true vision for the blind? This would turn a "limited problem" into an real asset - though no one knows at present if it can be made to work as hoped for. Best regards, Peter Meijer Hi Bernard,

Thank you for this nice and well-written article about CBS!

I proposed at

Sound-Induced Mental Imagery for the Blind

After all, realistic visual hallucinations with the visual
content tightly bound to live but crossmodally encoded camera
views would be very much like… true vision for the blind?
This would turn a “limited problem” into an real asset – though
no one knows at present if it can be made to work as hoped for.

Best regards,
