A photograph of the eye of a patient with Wilson's disease, showing a Kayser-Fleischer ring. Wilson's disease, also called hepatolenticular degeneration, is a rare autossomal recessive inherited disease. It is primarly caused by an acumulation of copper in tissues all over the body, mainly in the liver, brain, kidneys and cornea. The Kayser-Fleischer ring consists of copper deposition in the cornea. It presents as a greenish or golden brown ring around the cornea.
