[Clinical Picture] Lipaemia retinalis in familial chylomicronaemia syndrome
A 5-year-old boy presented to our department with a 2-day history of acute febrile illness. During evaluation, his blood samples were found to be so lipaemic (figure) that it caused interference in analyte measurements. The child was born of a non-consanguineous marriage, there was no history of failure to thrive or developmental delay, and there were no reports of any previous episodes of acute pancreatitis. Neither xanthomata nor hepatosplenomegaly was found at clinical examination. Laboratory test results found a normal fasting blood glucose concentration (4·5 mmol/L).
