Abstract/OtherAbstract:
Objective: Cognitive outcomes and structural changes in the central nervous system were assessed in children born at term small-for-gestational-age (SGA) who showed a normal umbilical artery (UA) Doppler. Outcomes were assessed when the children were 5-6.5 years of age. We used a novel approach to examine changes in neuronal integrity of the optic nerve. Methods: Two cohorts of infants born SGA (n = 40) and appropriate-for-gestational-age (AGA) weight (n = 39) were compared. Neuronal damage was evaluated using optical coherence tomography (OCT) of the optic nerve. Cognitive deficits were assessed with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Visuospatial perception was evaluated with the Rey-Osterreich Complex Figure (ROCF) tasks. Results: SGA infants showed significantly lower average retinal nerve fiber layer (RNFL) thickness (98.2 vs 104.5 µm; p = 0.012). The SGA group exhibited impaired performance in copy tasks on the ROCF (3.27 vs 3.56; p = 0.036), and a higher rate of suboptimal WPPSI Performance IQ, compared with AGA infants (15% vs 0%; p = 0.025). Conclusions: Term infants born SGA with normal UA Doppler are at increased risk for cognitive deficits and axonal loss in the RNFL at the age of 5-6.5 years. Copyright © 2012 ISUOG.
