Definition
Charles Bonnet syndrome (CBS) refers to the presenceof visual hallucinations in individuals with visual acuity loss without havingpsychosis or dementia. The condition is likely caused by the brain continuing to interpret images, even in their absence. Underlying conditions of vision loss associated with Charles Bonnet syndrome are diverse (including conditions such as macular degeneration and stroke) and may affect the eye, optic nerve, or brain. Hallucinations often resolve if the underlying vision deficit is corrected and can also remit in some individuals with static or progressive vision loss. Treatment is individualized.
