Charles bonnet syndrome, management with simple behavioral technique

J Neurosci Rural Pract. 2013 Jan;4(1):63-5. doi: 10.4103/0976-3147.105618.


Charles Bonnet syndrome occurs in visually impaired but cognitively normal individuals. This report describes a condition of vivid visual hallucination (phantom images) in an 85-year-old conscious man, who had been blind by bilateral progressively worsening glaucoma. This common, but rarely reported, condition was managed by behavioral approach of repeated blinking, intermittent eyes closure, and reassurance. While emotional, mood and cognitive disorders need to be ruled out, the condition, though frightening to the afflicted, is benign and remediable with simple, inexpensive approach. Health workers managing people with terminal blindness should always ask for the presence of hallucinations from their patients to forestall a preventable distress resulting from wrong perception without visual stimulus.
