  • Title: Pathogenetic significance of venous hyperoxaemia in retinopathy of prematurity.
    Author: Gmyrek D, Graupner K, Koch R, Schwarze R, Schulze A.
    Journal: Acta Paediatr Hung; 1987; 28(1):1-8. PubMed ID: 3620192.
    Abstract:
    Ten underweight newborns with severe retinopathy of prematurity (ROP) and 18 newborns with slight changes in the sense of ROP were compared with 66 healthy infants. The distribution of 13 possibly pathogenetically effective features in these 3 groups of patients was studied by means of variance analysis. The greatest significance resulted for multiple blood transfusions and exchange transfusions. From this it was concluded that the toxic oxygen effect on the immature retina was probably more dependent on the venous PO2 (determined by Hb concentration, O2-affinity, arterial PO2, and blood flow) than on the isolated arterial PO2.
