Electroretinography in Neonates Treated With Phototherapy

Abstract
Electroretinographic (ERG) studies were performed in 22 normal control newborns and 28 neonates who had had phototherapy [for hyperbilirubinemia] during the first few days of life. Mean age at ERG testing was 16.8 .+-. 2.9 days in the phototherapy group and 16.4 .+-. 3.7 days in the control group. Results of routine funduscopy were normal in both groups. Amplitudes of a and b waves under dark- and light-adapted states were similar in both groups. Phototherapy did not appear to have deleterious effects on photopic and scotopic retinal function in infants whose eyes were adequately shielded.
