Kayser–Fleischer rings (KF rings) are dark rings that appear to encircle the iris of the eye. They are due to copper deposition in part of the cornea (Descemet’s membrane) as a result of particular liver diseases. They are named after Dr. Bernhard Kayser and Dr. Bruno Fleischer the German doctors who first described them in 1902 and 1903. Initially thought to be due to the accumulation of silver they were first demonstrated to contain copper in 1934.
