title: Unilateral Kayser-Fleischer ring.
abstract: A patient is presented who had unrecognised Wilson's disease. He had developed a clinically obvious Kayser-Fleischer ring in only one eye. The eye without the corneal ring had been injured in childhood and had a low intraocular pressure. Possible mechanisms for formation of a Kayser-Fleischer ring are reviewed and the lack of Kayser-Fleischer ring in this case is discussed.
