Unilateral K-F ring in Wilson's disease

Abstract

Wilson's disease, also called hepatolenticular degeneration, has varied clinical manifestations and poses diagnostic challenges. Kayser-Fleischer ring, when present, is considered pathognomic of Wilson's disease. Although its presence is most commonly seen with the neuro-psychiatric form of the disease, it can also be present in hepatic form and asymptomatic patients. We report a case of unilateral Kayser-Fleischer ring in the normal, functional eye of a patient which subsequently led to the diagnosis of Wilson's disease in the patient. This case also highlights the examination of the normal appearing eye in all the patients presenting with complaints in only one eye.

Keywords: Kayser-Fleischer ring; Wilson’s disease; diagnosis; unilateral.
