Abstract

Objective: To determine if visuocortical development in premature infants with high bilirubin levels is more adversely affected than that in full-term infants.

Study design: 57 preterm infants were managed using institutional guidelines for hyperbilirubinemia. At 12-months corrected age, Vernier acuity, contrast sensitivity, and grating acuity measured using the sweep visual evoked potential (sVEP) were correlated to total serum/plasma bilirubin (TSB) levels in the first week of life.

Result: As TSB levels increased, Vernier acuity worsened in infants <34 weeks' gestation compared with those >34 to <37 weeks' gestation (p < 0.001). Contrast sensitivity varied as a function of TSB levels (Spearman correlation 0.63, p < 0.001). Grating acuity was unaffected.

Conclusion: Vernier acuity in preterm infants <34 weeks' gestation is more vulnerable to the effects of bilirubin, suggesting that the extrastriate visual cortex is primarily affected by bilirubin. Therefore, guidelines for management of hyperbilirubinemia in preterm infants (<34 weeks' gestation) should be revised.

期刊介绍： The Journal of Perinatology provides members of the perinatal/neonatal healthcare team with original information pertinent to improving maternal/fetal and neonatal care. We publish peer-reviewed clinical research articles, state-of-the art reviews, comments, quality improvement reports, and letters to the editor. Articles published in the Journal of Perinatology embrace the full scope of the specialty, including clinical, professional, political, administrative and educational aspects. The Journal also explores legal and ethical issues, neonatal technology and product development. The Journal’s audience includes all those that participate in perinatal/neonatal care, including, but not limited to neonatologists, perinatologists, perinatal epidemiologists, pediatricians and pediatric subspecialists, surgeons, neonatal and perinatal nurses, respiratory therapists, pharmacists, social workers, dieticians, speech and hearing experts, other allied health professionals, as well as subspecialists who participate in patient care including radiologists, laboratory medicine and pathologists.
