Charles bonnet syndrome
MONDO:0022140
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.

Visual release hallucinations
Visual release hallucinations, also known as Charles Bonnet syndrome (CBS), are a type of psychophysical visual disturbance in which a person with partial or severe blindness experiences visual hallucinations. First described by Charles Bonnet in 1760, the term Charles Bonnet syndrome was first introduced into English-speaking psychiatry in 1982. A related type of hallucination that also occurs with lack of visual input is the closed-eye hallucination.
