A 34 years old man was prescribed pregabalin 75 mg per day for chronic back pain. After 2 weeks of the start of the therapy, the patient developed seeing circular dark spots in his vision in the left eye along with decreased colour perception for all colours. The drug was stopped and the circular dark spots in his vision decreased gradually and colour perception was better after 7-10 days. The patient had no history of prior disturbance of vision. He was non-, diabetic and non-hypertensive. The event recurred when a combination drug containing pregabalin and methylcobalamin was administered after 6 months. The drug was stopped immediately and the event resolved.
