“…The present results are in agreement with those of several studies demonstrating decreased VEP amplitudes in preterm populations 8 24. We report normal latency, which was found in the same cohort at 5 years,3 in contrast to previous reports of delayed latencies in study groups at the ages of 4–6 years24 and 11 years 8. However, essential differences exist between our study and those of earlier ones, which included extremely preterm children,8 very low birthweight children8 and appropriate for gestational age children in their control groups,3 as opposed to the full-term controls used here.…”

“…Compared with term-born peers, MLP infants are at double the risk of neurodevelopmental disability at 2 years of age, with most impairment observed in the cognitive domain, supporting the notion that even with MLP gestations, preterm birth may impede the normal trajectory of brain development 23. The present results are in agreement with those of several studies demonstrating decreased VEP amplitudes in preterm populations 8 24. We report normal latency, which was found in the same cohort at 5 years,3 in contrast to previous reports of delayed latencies in study groups at the ages of 4–6 years24 and 11 years 8.…”

“…21 At the midoccipital electrode location (Oz), the waveform obtained with this method is characterized by a negative component peaking at around 75 milliseconds after stimulus onset (N75 or N1), followed by a positive component at 100 milliseconds (P100 or P1). 22 In children born preterm as compared to full-term, some studies have shown lower P1 amplitudes 23,24 and longer P1 latencies 24 whereas others have reported shorter P1 latencies 22 and N1 latencies 25 or else no significant differences at all. 26,27 These contradictory findings likely reflect the fact that, in many of the studies, participants were not stratified by neurologic status.…”

Visual Development and Neuropsychological Profile in Preterm Children from 6 Months to School Age

et al. 2014

The aim of this semilongitudinal study was to investigate the development of central visual pathways in children born preterm but without major neurologic impairments and to establish their cognitive and behavioral profile at school age. Ten children born preterm were assessed at 6 months and at school age, using visual evoked potentials at both time points and cognitive and behavioral tests at school age. We also tested 10 age-matched children born full-term. At 6 months' corrected age, we found no significant differences between preterm and full-term groups for either amplitude or latency of N1 and P1 components. At school age, the preterm group manifested significantly higher N1 amplitudes and tended to show higher P1 amplitudes than the full-term group. We found no significant differences in cognitive and behavioral measures at school age. These results suggest that preterm birth affects visual pathways development, yet the children born preterm did not manifest cognitive problems.

“…In fact, because that maturation of the visual system not only takes place during the prenatal period, but also continues during the first years of life (Chau, Taylor, & Miller, 2013), it is considered immature at birth in full-term children, even more so in preterm children. Throughout the years, many VEP studies have supported this view, by showing lower amplitudes in preterm samples (Feng et al, 2011;Hammarrenger et al, 2007;Kuba et al, 2008) in response to pattern-reversal stimuli, which were interpreted as a disruption of normal visual development. Consequently, our results regarding lower N2 amplitudes in preterms at 12 months for oriVEP and texVEP suggest that processing of orientation and textured visual stimuli, which is related to feedforward connections, is poorer for these children when compared to their full-term counterparts of the same age.…”

Early childhood development of visual texture segregation in full-term and preterm children

et al. 2015

To date, very little is known about the normal development trajectory of visual texture segregation, or how it is affected by preterm birth. The goal of this study was to characterize the development of visual texture segregation using texture segregation visual evoked potentials (tsVEPs) in children born full-term and children born preterm without major neurological impairment. Forty-five full-term and 43 preterm children were tested at either 12, 24 or 36 months of age (corrected age for prematurity at 12 and 24 months old). VEPs were obtained using two lower-level stimuli defined by orientation (oriVEP) and two higher-level stimuli defined by texture (texVEP). TsVEP was obtained by dividing by two the subtraction of oriVEP from texVEP. Results show a clear maturation of the processes underlying visual texture segregation in the full-term group, with a significant N2 latency reduction between 12 and 36 months of age for all conditions. Significant N2 amplitude reduction was observed for oriVEP between 12 and 24 months, as well as for texVEP between 12 and 24 months, and 12 and 36 months. Comparison between full-term and preterm children indicated significantly lower N2 amplitude for the preterm group at 12 months for oriVEP and texVEP. These differences were no longer apparent at 24 months of age, suggesting that children born preterm catch up with their full-term counterparts somewhere between 12 and 24 months of age. Our results appear to reflect a maturational delay in preterm children in both lower-level and higher-level visual processing during, at least, early childhood.
