Sunflower cataract: do not forget Wilson's disease

A 41-year-old man with liver cirrhosis of unknown aetiology for 6 years was admitted to our department to confirm the diagnosis of Wilson9s disease. He consulted an ophthalmologist who suspected the presence of a sunflower cataract and Kayser–Fleischer ring. At admission, his liver function tests were modestly impaired (Child–Pugh C, 10 pts). Neurological examination was normal, but cognitive functions were mildly impaired. Based on the copper metabolism abnormalities and clinical manifestation, we diagnosed Wilson9s disease (Ferenci score, 6 pts) and started treatment with d-penicillamine. Presenting the case we would like to emphasise the significance of the ophthalmological examination in Wilson9s disease diagnosis.
