Purpose: The aim of this study is to investigate the prevalence and clinical characteristics of Charles Bonnet syndrome (CBS) in a group of Turkish patients with various retinal diseases. Methods: Two hundred and sixty-four patients with a best-corrected visual acuity of <= 20/40 in the better-seeing eye were asked with a standardized question whether they had symptoms of CBS. If they responded positively, a questionnaire was verbally administered to learn more about the details of the symptoms. Results: There were 125 (47.3%) females and 139 (52.7%) males with a mean age of 72.1 years (range 31-90). Seventeen (6.4%) patients were diagnosed with CBS. Three (17.7%) patients had noncomplex hallucinations and 14 (82.3%) had complex hallucinations. Conclusion: CBS is not uncommon in visually impaired patients with retinal disease. Clinicians who care for visually impaired patients should be aware of CBS. (C) 2016 S. Karger AG, Basel
