Neonatal jaundice treatment. View of a premature baby undergoing phototherapy to treat jaundice. Neonatal jaundice consists of yellowing of the skin and whites of the eyes due to the accumulation of bilirubin, a bile pigment, in the blood. It is a common condition in babies and especially for premature ones. It is usually caused by immaturity of the liver which does not excrete bilirubin efficiently. The blue light causes the chemical breakdown of bilirubin which is then excreted in the urine. The baby's eyes are covered to protect them from this light.
