In the rare inherited disease – Wilson’s disease – named after a doctor who described it, copper accumulates abnormally mainly in the liver and brain. Because of excess copper, the lens of the eye can look like a sunflower – sunflower cataracts. A cararact is cloudiness of the eye’s lens which can result from numerous causes.
Treatment for Wilson’s disease includes avoiding foods with copper, using medications which prevent absorption of dietary copper or bind to copper within the body and liver transplantation.
