Definition
The Kayser-Fleischer rings are an ocular symptom due to the deposition of copper in the corneal tissue; therefore, they are typically associated with Wilson's disease and progression status. They appear as circular or semi-lunar formations of golden or brown-greenish color, which arise at the periphery of the cornea, more precisely at the level of the Descemet membrane (border area between the cornea and the sclera). As Wilson disease progresses, other half-moons may appear to affect the entire circumference of Descemet's membrane.
The Kayser-Fleischer rings can be seen on examination with the slit lamp, an instrument used in the eye sector, and sometimes even with the naked eye.
Rarely, the Kayser-Fleischer rings occur in other disorders of the liver and in the course of diseases that lead to cholestasis (eg primary biliary cirrhosis).
