PURPOSE: Vision loss from age-related macular degeneration (AMD) has a profound effect on vision-related quality of life (VRQoL). The pupose of this study is to identify clinical factors associated with VRQoL using the Rasch- calibrated NEI VFQ-25 scales in bilateral advanced AMD patients. METHODS: We retrospectively reviewed 47 patients (mean age 83.2 years) with bilateral advanced AMD. Clinical assessment included age, gender, type of AMD, high contrast visual acuity (VA), history of medical conditions, contrast sensitivity (CS), central visual field loss, report of Charles Bonnet Syndrome, current treatment for AMD and Rasch-calibrated NEI VFQ-25 visual function and socioemotional function scales...

For fear of being ridiculed, individuals with visual hallucinations hide their experiences and thus remain unrecognized and miss treatment. An elderly blind woman secondary to glaucoma experienced visual hallucinations accompanied by gross behavior disturbances. She improved with sodium valproate after haloperidol failed and remained relatively improved upon 3 months follow-up.

Charles Bonnet syndrome (CBS) is a diagnosis of exclusion. Typical affected patients have impaired visual acuity, vivid recurring visual hallucinations, and no cognitive impairment. Vision loss is most commonly due to macular degeneration, although many other causes exist. Here, we report a case of an 87-year-old woman with CBS and discuss the diagnosis and treatment.

Purpose: To report a case of closed-eye visualizations and to clarify the different types of hallucinations and their etiologies. Methods: Retrospective case report of a patient with closed-eye visualizations secondary to hyponatremia. Clinical findings, physical exam, laboratory assessment, treatment, and disease course from the patient's hospitalization were used in creating this report. Follow-up data after discharge were also obtained. Results: Closed-eye visualizations were diagnosed as secondary to hyponatremia, as they did not occur with the eyes open, and potential alternate causes were excluded...

Background: Charles Bonnet syndrome is characterized by formed visual hallucinations in individuals with vision loss. It is reported that one in five older adults with vision loss suffer from Charles Bonnet syndrome and the suspected lack of awareness amongst family physicians may lead to misdiagnosis and inappropriate treatment. Objective: To assess Canadian family physicians' awareness of Charles Bonnet syndrome. Methods: We conducted a national perception and practices survey of family physicians across Canada to assess (i) the level of awareness of Charles Bonnet syndrome amongst family physicians; (ii) the frequency of family physicians' encounters with patients with visual hallucinations and (iii) management strategies and referral patterns for patients with Charles Bonnet syndrome presenting to family physicians...

We assessed incidence, predictors, and impact on 6-month mortality of contrast-induced acute kidney injury (CI-AKI) after coronary angiography with or without percutaneous coronary intervention in patients with acute coronary syndrome (ACS), according to 3 different CI-AKI definitions. Serum creatinine (sCr) was assessed at baseline and 48 to 72 hours after procedure to classify patients into 3 CI-AKI groups: Group 1: increase in sCR ≥25% over baseline but absolute increase <0.5 mg/dl; Group 2: absolute increase ≥0...

Descriptions of hallucinatory phenomena have figured prominently since the beginning of recorded history. Jean Etienne Esquirol (1772-1840) is usually credited for having introduced the term in 1817, differentiating between hallucinations and illusions. Both are wrong perceptions, but in illusions, an external stimulus is always present whereas hallucinations are perceptions that occur in the absence of corresponding sensory stimuli. They occur in a variety of conditions but more often in the mentally ill, especially in schizophrenia where hallucinations, particularly auditory hallucinations represent for many, such as Henri Ey one of the cardinal features...

Purpose: We investigate the prevalence of the Charles Bonnet syndrome (CBS) in patients with neovascular age-related macular degeneration (AMD) and analyze the role of oral proton pump inhibitors (PPIs) and other potential risk factors. Methods: A total of 510 consecutive patients with neovascular-AMD followed at a single tertiary center in Portugal were screened for CBS. Using a structured questionnaire, psychiatrically healthy individuals were interviewed systematically and divided into a CBS group and a non-CBS group...

Charles Bonnet Syndrome describes the triad of complex visual hallucinations secondary to ophthalmic pathology in psychologically normal people. We present a rare case of acute-onset Charles Bonnet Syndrome following cardiac surgery that resulted in profound loss of visual acuity in both eyes with characteristic visual hallucinations that were initially mistaken for delirium. Computed tomography of the brain revealed bilateral occipital infarcts, providing the substrate for Charles Bonnet Syndrome. A high index of suspicion should be maintained in cognitively intact patients with visual loss who are also experiencing visual hallucinations to ensure prompt diagnosis and management of this often overlooked condition...

Charles Bonnet Syndrome (CBS) is a common cause of visual hallucinations seen in elderly people with visual impairment. Well-formed visual hallucinations in clear consciousness with preserved insight are commonly reported in literature. We report a case of CBS having multisensory hallucinations. An elderly patient with visual impairment fulfilling the criteria of CBS presents with various modalities of hallucinations viz. visual, auditory and tactile hallucinations improved completely with low dose of antipsychotics...

OBJECTIVES: Charles Bonnet syndrome (CBS) is a common cause of visual hallucinations in older people. The relationship between CBS and cognitive impairment is unclear, but anecdotal reports exist of dementia emerging in patients diagnosed with CBS. This work set out to determine if there is an increased incidence of dementia, and increased severity of cognitive impairment, in people with CBS compared to controls from the same clinical setting. METHOD: People over 65 attending low-vision and glaucoma clinics, and a cohort of age-matched controls, underwent a psychiatric assessment...

Individuals with Charles Bonnet syndrome (CBS) typically have severe visual loss and experience visual hallucinations yet have no psychiatric disease. Visual impairment often is due to end-stage glaucoma or macular degeneration. We report 3 cases of CBS in patients who underwent an oculoplastic surgical procedure. One patient experienced binocular visual distortion due to excessive topical ophthalmic ointment, and 2 patients experienced monocular visual impairment from patching. Visual hallucinations resolved once vision returned to baseline...

Musical hallucination is a disorder of complex sound processing of instrumental music, songs, choirs, chants, etc. The underlying pathologies include moderate to severe acquired hearing loss (the auditory equivalent of Charles Bonnet syndrome), psychiatric illnesses (depression, schizophrenia), drug intoxication (benzodiazepines, salicylate, pentoxifylline, propranolol), traumatic lesions along the acoustic pathways, and epilepsy. The hallucinations are most likely to begin late in life; 70% of patients are women...

Charles Bonnet syndrome (CBS) can develop after trans-sphenoidal adenomectomy (TSA); however, the neural mechanisms remain unknown. Sensory deprivation and releasing phenomenon are both hypothetical explanations for this condition; however, there is no definite evidence that strongly supports either supposition. We report the first case of CBS after TSA without optic nerve atrophy. Postoperatively, the patient's vision seemed to be relatively well preserved, apart from the left-side hemianopsia in the right eye...

BACKGROUND: Charles Bonnet Syndrome (CBS) is a rare clinical condition which is characterized by complex hallucinations in visually impaired patients. The pathophysiology of this disorder remains largely unknown, and there is still no proven treatment for this disease. In our study, we aimed to investigate the neural activity through Electroencephalography (EEG) power and evaluate the effect of rivastigmine in combination with alpha-lipoic acid on hallucination in two CBS patients with diabetic retinopathy...
