Abstract: Introduction: Charles Bonnet syndrome (CBS) is a neuropsychiatric clinical condition characterized by the presence of visual hallucinations in patients with preserved cognitive status and significant deterioration of vision. In view of the emotional disturbance caused by this disease, recognizing its symptoms is essential in the management of these patients. Objectives: To highlight the importance of Charles Bonnet Syndrome diagnosys for the quality of life of people with declining visual acuity. 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: It is estimated that CBS occurs in 11-15% of the population with vision loss. Variations in prevalence between studies are probably due to differences in population, age, etiology of visual impairment and underdiagnosis of the condition. It occurs days or weeks after visual field loss, 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. They may disappear by closing their eyes, changes in lighting or gaze direction and increased social contact. Many patients prefer to hide their disorder for fear that they are suffering from a serious psychiatric illness and often receive inadequate answers when they question their visions. It is strictly important to recognize differential diagnoses, ruling out serious causes of visual hallucinations such as psychiatric, neurological, ocular disorders or drug intoxication. Knowledge of CBS, which is often underdiagnosed and unidentified, is therefore essential. Conclusion: Considering the emotional upheaval caused by this disease, the diagnosis of CBS is essential for relieving patients suffering. Follow-up and the choice of effective and appropriate therapeutic treatment are necessary.
