A Trial of Patients With a Charles Bonnet Syndrome
キーワード
概要
説明
Patients with a visual acuity of 0.5 LogMAR or less in the better eye were screened for CBS. Instruments used were an interview asking for details of the hallucinations, a mental test and a scale concerning quality of life. Patients with CBS were randomized by minimization in two groups: in group 1, a patient-doctor interview by an ophthalmologist was performed and in group 2 an interview and if needed, a therapy by a psychiatrist. At the 3-months follow up, the psychological strain of patients was recorded again.
