Charles Bonnet Syndrome, Time to Drop the Name?

Dear Editor

The report by A Fernandez and others (Ref: Int. J. of Geriatr. Psychiat. 11(a), 1996) is probably one of the more thoroughly investigated cases of `Charles Bonnet Syndrome'.

The available evidence so far seems to point to an organic cause, most probably a cerebrovascular event. It is unlikely that end-organ pathology alone could produce such complex visual imagery. Ocular pathology at best may only be a co-existing disorder. There is probably little to be gained in continuing to refer to the disorder by its present eponym, which is unlikely to be of any help both in terms of aetiology and treatment. It appears sensible to classify the disorder as `organic visual hallucinosis'. It is clearly distinguished from visual hallucinosis of a dissociative disorder as the latter is more likely to have its origin in younger age groups and is probably unresponsive to neuroleptic medication.
