Wilson's disease presenting with rapidly progressive visual loss: another neurologic manifestation of Wilson's disease?

Wilson's disease (WD) is a rare autosomal recessive disorder of copper metabolism resulting in copper-induced tissue damage that primarily involves the liver and central nervous system. The neurologic manifestations of WD almost universally involve a derangement of basal ganglia function or psychiatric disturbance. We report the case of a 46-year-old man presenting with end-stage liver disease caused by WD who had associated rapidly progressive optic neuropathy. We also discuss the possible association between the two conditions.
