Definition

Charles Bonnet syndrome (CBS) is named after the Swiss naturalist Charles Bonnet; In 1760 he described a condition in which vivid, complex visual hallucinations (fictive visual percepts) occur in mentally healthy people; He first documented it in his 87 year old grandfather, who was nearly blind from cataracts in both eyes but perceived men, women, birds, carriages, buildings, tapestries and scaffolding patterns; Most who are affected by this are people with visual impairments due to old age, damage to the eyes or optic pathways
