Jaundice, also known as
icterus (attributive adjective: "icteric"), is yellowish discoloration of the
skin,
sclera (whites of the eyes) and
mucous membranes caused by hyperbilirubinemia (increased levels of
bilirubin in the blood). This hyperbilirubinemia subsequently causes increased levels of
bilirubin in the extracellular fluids. Typically, the concentration of bilirubin in the
plasma must exceed 1.5
mg/
dL, three times the usual value of approximately 0.5
mg/
dL The majority of this bilirubin comes from the breakdown of heme from expired red blood cells in the process just described. However approximately 20 per cent comes from other heme sources, including ineffective erythropoiesis, breakdown of other heme protrins such as muscle myoglobin and cytochrome enzymes.
Jaundiced eye
It was once believed persons suffering from the medical condition jaundice saw everything as yellow. By extension, the jaundiced eye came to mean a prejudiced view, usually rather negative or critical.
Alexander Pope, in 'An Essay on Criticism' (1711), wrote: "All seems infected that the infected spy, As all looks yellow to the jaundiced eye." Similarly in the mid 19th century the English poet Lord
Alfred Tennyson wrote in the poem 'Locksley Hall': "So I triumphe'd ere my passion sweeping thro' me left me dry, left me with the palsied heart, and left me with a jaundiced eye."
