Kayser-Fleischer corneal ring
The Kayser-Fleischer corneal ring (cornea = cornea) is a change in the cornea of the eye as a characteristic symptom of Wilson's disease .
description
Wilson's disease is an inherited metabolic disorder with copper overload in the body. At the edge of the cornea, a greenish, sometimes brownish, ring forms due to the deposition of copper in the Descemet's membrane . The ring doesn't have to be completely closed. The findings can be ascertained particularly clearly in the examination with the slit lamp . Often the phenomenon is so clear that one can speak of a visual diagnosis . The corneal ring is named in honor of the German ophthalmologists Bernhard Kayser and Bruno Fleischer , who described it in 1902 and 1903, respectively.
“Kayser Fleischer Corneal Rings” must not be confused with the “ Fleischer Ring ” that can occur with keratoconus . Here there is increased iron deposition from the tear film.
