Eye measurements in preterm and term newborn infants

The purpose of this study was to establish normal anthropometric standards for eye measurements in newborn infants born between 27 and 41 weeks of gestation. In 198 term and preterm newborn infants, palpebral fissure size and inner and outer canthal distances were measured and the interpupillary distance was calculated. The mean and 2 SD from the mean for each gestational week was determined, and the normal values are presented as intrauterine growth curves of these parameters for gestational age.
