Pigmented corneal rings in a patient with primary biliary cirrhosis.
A patient with primary biliary cirrhosis who had high hepatic, serum, and urine copper levels was found by slit-lamp biomicroscopy to have pigmented corneal rings similar to Kayser-Fleischer rings. Wilson's disease was excluded on the basis of the elevated serum ceruloplasmin and copper levels, the lack of neurological disease despite advanced liver disease, a negative family history, and the typical clinical features of primary biliary cirrhosis. Although the exact chemical nature of the corneal rings is unknown, the cornea may be another tissue associated with elevated tissue copper levels in primary biliary cirrhosis.
