“…It can also be classified as a pseudohallucination, in which the hallucinatory experience has characteristics more similar to those of the representative image, especially the absence of corporeality and location in the internal subjective space. Finally, it can be classified as hallucinosis, with the hallucinatory experience located in the external objective space caused by an organic impairment and which is promptly criticized by the individual, who recognizes it as something unreal (5,6,7).…”

“…Antiepileptics have been used as medications and can reduce or extinguish visual hallucinations in some cases, while the use of antipsychotics does not always provide an effective response, so favorable results have only been reported in isolated cases. The use of pharmacotherapy is indicated according to the characteristics and severity of each case (6,8).…”

Introduction: Charles Bonnet syndrome (CSB) is a neuropsychiatric clinical condition characterized by the presence of visual hallucinations in patients with significant deterioration of vision and preserved cognitive status. Considering the emotional disorder caused by this pathology, recognizing the symptoms is essential in the therapeutic management of these patients. Goal: Highlight the importance of the diagnosis of CBS for the quality of life of the population with decline in acuity and visual field. Method: Integrative literature review based on 8 articles taken from the "Scielo" and "Pubmed" databases, using the descriptors "Charles Bonnet Syndrome" and "Vision Disorders". Results: CBS is estimated to occur in 11-15% of the population with vision loss. Variations between studies regarding prevalence are probably due to differences in population, age, etiology of visual impairment and underdiagnosis of the condition. The occurrence occurs after days or weeks of loss of visual field, persisting from minutes to years. Patients describe simple or complex figures, such as people, animals, inanimate objects or scenes, often irritating ones that cause fear, worry, anxiety and disturbance. Such visual hallucinations may disappear with closing the eyes, changes in lighting or gaze direction, and increase with social contact. Many patients prefer to hide their disorder for fear of having a serious psychiatric illness and often when they question their views they receive inadequate responses. It is strictly important to recognize differential diagnoses, ruling out serious causes of visual hallucinations, such as psychiatric, neurological, ocular disorders or drug intoxication. Therefore, it is essential to know about CBS, which is often underdiagnosed and unidentified. Conclusion:In view of the emotional disorder caused by this disease, the diagnosis of CBS is essential to alleviate the suffering of patients.It is necessary to monitor and choose effective and appropriate therapeutic management.

A Síndrome de Charles Bonnet (SCB) é uma condição na qual há ocorrência de alucinações visuais em indivíduos que apresentam alguma patologia ao longo das vias visuais. Estes pacientes geralmente mantém cognição intacta e insight da irrealidade das alucinações. O tratamento é baseado em abordagem multiprofissional com reforço ao paciente quanto à benignidade das alucinações, porém quando estes métodos falham, a terapia medicamentosa tem se mostrado pouco promissora. Neste trabalho será apresentada uma revisão acerca da síndrome e o relato de caso de um paciente que obteve boa resposta ao tratamento farmacológico com Clobazam 10mg/dia.Palavras-chave: Síndrome de Charles Bonnet, Benzodiazepinas, Alucinações

Since its first description in 1760, Charles Bonnet syndrome (CBS) has been reported in many studies. The main characteristics are visual hallucinations, preserved awareness of unreal visions, and absence of psychotic symptoms. CBS can occur with lesions located anywhere along the central visual pathway, from the eye to the calcarine fissure.ObjectiveTo describe patients with CBS and carry out a review of the literature.MethodsSix patients with visual hallucinations were evaluated in an outpatient memory clinic between 2001 and 2008, and their clinical characteristics recorded.ResultsFour patients were female, and the mean age was 74.5±16.9 years. Three patients had visual loss secondary to eye disease and three due to cerebral lesions. The visions consisted of animals, persons, moving objects, bizarre creatures or colored forms, and were considered disturbing by five patients. Five patients received treatment, and only three reported partial benefit from the therapy. Complete recovery was not seen in any of the subjects.ConclusionsCBS is relatively rare and its recognition is important to avoid misdiagnoses with psychiatric or dementing illnesses.
