title: On the presence of bilirubin in the ocular humors of premature infants.
abstract: The yellow pigments observed in the ocular humors of premature infants were identified as the plasma pigments bilirubin and oxyhemoglobin. The blood/vitreous humor barrier to bilirubin was estimated to be (1/0.11) for total bilirubin and (1/0.25) for direct-acting bilirubin. Hall method histochemical staining for bilirubin in sections of premature infant eyes was highly positive for the vitreous humor, and suggestive of uptake of bilirubin by the neural-retinal cells.
