Abstract

The Charles Bonnet syndrome (CBS) is a condition associated with complex visual hallucinations occurring in the elderly in patients with visual impairment and normal mental health. Here, we report the case of a 78-year-old woman who has a limited visual acuity with a CBS that we postulated to be in relationship to a vitamin B12 deficiency. This case is the first report of vitamin B12 deficiency-associated CBS.
