Purpose: This study was to conducted to evaluate the usefulness of light adapted electroretinography (ERG) using the RETevalTM system (LKC Technologies, Gaithersburg, MD, USA) in preterm infants without retinopathy of prematurity.
Methods: Overall, 18 preterm infants underwent light adapted ERG using the RETevalTM system without sedation. Readable results were acquired from 11 patients (61%) and the mean gestational age at birth was 33 ± 3 weeks.
Results: The amplitude and implicit time of the ‘a’ wave was -8.1 ± 6.6 μV and 17.3 ± 7.8 ms, respectively, while those of the ‘b’ wave was 20.4 ± 13.6 μV and 36.7 ± 8.8 ms, respectively. Additionally, 30-Hz flicker results were obtained with an amplitude and implicit time of 6.0 ± 3.8 μV and 32.3 ± 2.8 ms, respectively. Negative correlation was found between the ‘a’ wave amplitude and age at examination (p < 0.05). The light-adapted 3.0 ERG response was decreased in preterm infants and a larger decrease in ‘b’ wave amplitude than ‘a’ wave amplitude was observed, which corresponds to the histological maturation of the retina.
Conclusions: Our study indicates that RETevalTM system is useful for evaluating retinal function in preterm infants.
