OBJECTIVES: To study Charles Bonnet syndrome (CBS) and its characteristics in the Service of Ophthalmology at the San Carlos Clinical Hospital in Madrid. METHODS: 45 patients referred from the Service of Ophthalmology diagnosed with CBS during the last year by the Units of Psychiatry, Neurology and Ophthalmology were studied. Characteristics of the hallucinations were checked, (colour and movement), duration, frequency, time of evolution, trigger factors and associated, and general and ocular associated pathology. RESULTS: 60 % were women with a visual acuty less than 0.3 in 99 % of the cases. In the vast majority the content of the hallucinations were people (40 %), plants and trees (30 %) and animals (10 %). In 55 % they were in colour and in movement. Average time of evolution was one year, with a frequency of daily hallucinations in 80 % of the cases. The main associate factors were the dazzle and low lighting. The major reason for blindness was DMAE followed by glaucoma. COMMENTS: CBS is a common disorder in our field due to increased quality of health care and life expectancy of our patients. Secondary visual deficits age-macular degeneration or glaucoma favours the development of CBS without the patient presenting a psychiatric pathology. CONCLUSIONS: CBS is a pathology whose knowledge is fundamental for ophthalmologist community to avoid inadequate diagnostic procedures or potentially harmful treatments.
