The Charles Bonnet Syndrome (CBS) is typically characterized by visual hallucinations in elderly people without cognitive defects. This article presents the case of an 80-year-old male patient with a one-year history of visual hallucinations, secondary to glaucoma, in both eyes. Neither a dopamine agonist nor cholinesterase inhibitor therapy improved his symptoms. In this case, the hallucinations were gradually improved after administration of a GABAergic drug, pregabalin, for diabetic polyneuropathy. Placebo-controlled clinical trials would be needed to support this effect of pregabalin, as suggested by this association.
