Purpose of review The aging of the population and the resultant increase in the number of patients with low vision due to age-related macular degeneration and other ocular diseases necessitate an increase in awareness of the Charles Bonnet syndrome among ophthalmic care providers. Recent findings The clinical features of Charles Bonnet syndrome have been described by several different authors as formed visual hallucinations due to disturbances of the visual system in patients who are otherwise… Expand
Charles Bonnet syndrome.
TLDR
It is prudent to become familiar with the Charles Bonnet syndrome so primary care optometrists can properly identify CBS and help their patients deal with it. Expand
Charles Bonnet syndrome.
TLDR
It is essential to distinguish CBS from mental illnesses, since patients with CBS are fully aware that hallucinations are not real, and therefore avoid patients being misdiagnosed. Expand
Seeing the unseen: Charles Bonnet syndrome revisited
TLDR
Three different ocular morbidities that have been reported to occur in conjunction with CBS are revisited and Psychiatrists and ophthalmologists alike must be sensitive to this clinical condition to ensure prompt diagnosis and treatment. Expand
Charles Bonnet syndrome: characteristics of its visual hallucinations and differential diagnosis.
TLDR
Physicians who care for low vision patients should be aware of CBS and appropriately diagnose its hallucinations after exclusion of psychiatric and neurologic diseases. Expand
The Prevalence and Characteristics of Charles Bonnet Syndrome in Turkish Patients with Retinal Disease
TLDR
Investigating the prevalence and clinical characteristics of Charles Bonnet syndrome in a group of Turkish patients with various retinal diseases found that CBS is not uncommon in visually impaired patients with retinal disease, and Clinicians who care for visually impairment patients should be aware of CBS. Expand
Charles Bonnet plus syndrome: apropos of a case
Purpose Charles Bonnet syndrome plus is an exceedingly rare variant of this disorder. The variant has been described in patients with sight impairment and severe hypoacusis, and is usuallyExpand
Charles Bonnet syndrome: characteristics of its visual hallucinations and differential
ABSTRACTObjective: To present an eight-case serie of patients with Charles Bonnet syndrome (CBS). Method: All patients were initially evaluated byan ophthalmologist and then submitted to a neurologicExpand
Atypical Charles Bonnet syndrome secondary to frontal meningioma: a case report
TLDR
This case aims to present the association of visual hallucinations with complex alterations of the nervous structures adjacent to the visual pathway and an atypical clinical presentation, thus explaining the possible mechanisms involved in the generation of these symptoms. Expand
Charles Bonnet syndrome in cranio-maxillofacial surgery: case report
TLDR
A 68-year-old male patient underwent an operation to repair a unilateral orbital floor fracture and subsequent eye patching by a Frost suture, and complained of complex, colored visual hallucinations three hours after waking from general anesthesia, which may result in acute onset of visual hallucinations.

TLDR
Ophthalmologists should be aware of Charles Bonnet's syndrome, since its prevalence is high among blind or visually impaired people: patients often are reluctant to admit their hallucinatory experiences, because of the fear of being stigmatised. Expand

The Charles Bonnet syndrome: a large prospective study in The Netherlands. A study of the prevalence of the Charles Bonnet syndrome and associated factors in 500 patients attending the University Department of Ophthalmology at Nijmegen.
TLDR
The findings support association of CBS with sensory deprivation and advanced age, as well as possible associated ophthalmic and sociodemographic factors. Expand
Charles Bonnet Syndrome in Age-Related Macular Degeneration: The Nature and Frequency of Images in Subjects with End-Stage Disease
TLDR
The prevalence of Charles Bonnet syndrome in late AMD is high, the main risk factor being poor better eye visual acuity, and the most commonly experienced hallucinations were of people. Expand
Dementia with lewy bodies and charles bonnet syndrome.
TLDR
Ophthalmologists and retina specialists, in particular, should be familiar with the features of dementia with Lewy bodies because the diagnosis of this condition can allow appropriate intervention and help prevent drug-related side effects. Expand
Rehabilitation in Charles Bonnet syndrome: a review of treatment options
TLDR
A review of the literature highlighted a range of visual, pharmacological and social management regimes that may alleviate visual hallucinations associated with Charles Bonnet syndrome, albeit using small samples in uncontrolled trials. Expand
Charles bonnet syndrome associated with age-related macular degeneration.
TLDR
Reestablishment of high resolution visual input leads to a dramatic and almost immediate increase in the stimulus threshold of visual cortex cells as reflected by resolution of symptoms. Expand
Charles Bonnet Syndrome: successful treatment of visual hallucinations due to vision loss with selective serotonin reuptake inhibitors
TLDR
This is the first case to show that selective serotonin (and noradrenalin) reuptake inhibitors may be an effective and well-tolerated treatment for visual hallucinations associated with vision loss, and it adds to evidence implicating serotonergic pathways in the pathogenesis of visual hallucinations. Expand
Treatment of typical Charles Bonnet syndrome with donepezil.
TLDR
The effectiveness of donepezil indicates that the patient's visual hallucinations might be related to dysfunction of cholinergic neurones, although she did not exhibit any cognitive decline, or morphological and physiological brain pathology, and it may be a safer option for the treatment of CBS in the elderly. Expand
Complex visual hallucinations (Charles Bonnet syndrome) in the hemianopic visual field following occipital infarction
TLDR
A rare variant of Charles Bonnet syndrome where such hallucinations occur in the hemianopic visual field of a patient with an occipital infarct whose visual acuity is largely unimpaired is described. Expand
Clinical evaluation of 14 patients with the Charles Bonnet syndrome (isolated visual hallucinations).
TLDR
A group of 14 patients with isolated visual hallucinations who met the criteria proposed by Gold and Rabins for Charles Bonnet syndrome (with the exception of the criterion "hallucinations are stereotyped") underwent psychiatric, neurologic, and ophthalmologic tests and it was concluded that a combination of factors is probably responsible for the Charles Bonnets syndrome. Expand
Visual loss and visual hallucinations in patients with age-related macular degeneration (Charles Bonnet syndrome).
TLDR
The extent of visual loss did not appear to be a predictor for the likelihood of a patient with age-related macular degeneration experiencing a CBS VH, nor was the progression of loss reflected in the complexity of the VHs reported. Expand
