Pregabalin in the treatment of Charles Bonnet syndrome

Charles Bonnet syndrome is a condition characterised by the presence of visual hallucinations in patients having visual impairment most commonly reported in the seventh decade. We describe a case of a 55-year-old lady who had developed retinopathy causing significant visual loss secondary to diabetes mellitus. She had started seeing images of men for the past 2 months which made her feel uncomfortable and seek psychiatric help. She was aware that the hallucinations were not real but a part of her imagination. A detailed history did not reveal any psychopathology but the patient had several medical complications due to her uncontrolled diabetes. Pregabalin, which was started for her neuropathy, dramatically remitted her symptoms within 2 days.
