what is the name of the condition from the image below where dark rings appear to encircle the iris of the eye?
Kayser-Fleischer rings (KF rings) are dark rings that appear to encircle the iris of the eye. They are due to copper deposition as a result of particular liver diseases. [1] They are named after Dr Bernhard Kayser and Dr Bruno Fleischer, the German doctors who first described them in 1902 and 1903.
