“…Two of our visual cognitive measures, the VMI and MVPT, correlated significantly with the IQ scores of the participants ( p < .05 and p < .005, respectively), with better performance correlated with higher IQ. These associations may be due to similarity in task demands, and are consistent with previous studies reporting a relationship between IQ and visual‐cognitive task performance in preterm children (Jongmans et al ., 1996; Davis et al ., 2005).…”

Many studies report chronic deficits in visual processing in children born preterm. We investigated whether functional abnormalities in visual processing exist in children born preterm but without major neuromotor impairment (i.e. cerebral palsy). Twelve such children (< 33 weeks gestation or birthweight < 1000 g) without major neuromotor impairment and 12 born full-term controls were assessed at 8-12 years of age by means of ophthalmological assessment (visual acuity, colour vision, stereopsis, stereoacuity, visual fields, ocular motility, motor fusion), cognitive tests of visual-motor, visual-perceptual and visual-spatial skills and pattern-reversal visual evoked potentials (PR-VEPs). All participants also underwent magnetic resonance imaging (MRI) of the brain and neuromotor assessments. No significant differences were found between the groups on the ophthalmological, visual cognitive, neurological, neuromotor or MRI measures. The P100 component of the PR-VEP showed a significantly shorter latency in the preterm compared with the full-term participants. Whilst this P100 finding suggests that subtle abnormalities may exist at the neurophysiological level, we conclude that visual dysfunction is not systematically associated with preterm birth in the context of normal neurological status.

“…Selon l'étude de Goyen, Lui et Woods (1998), 11 à 20% des enfants prématurés présenteraient des déficits au niveau des habiletés visuo-perceptuelles et visuo-motrices, alors que cette incidence s'élève à 71% en ce qui concerne la motricité fine. Ceux-ci peuvent se manifester en dépit d'un QI dans la moyenne (Davis, et al, 2005), ainsi qu'en l'absence d'atteintes neuromotrices (O'Reilly, et al, 2010). Notons, par ailleurs, que plus d'un tiers de ces enfants se voient prescrire des verres correcteurs, en comparaison à seulement 10% chez les enfants nés à terme (Saigal, et al, 2001).…”

ResumenLos nacimientos prematuros (≤ 37 semanas de gestación) se consideran una de las causas más importantes de mortalidad perinatal en las sociedades industrializadas. Hoy en día, gracias a la mejora de los cuidados pre-peri-y post-natales, es posible salvar a niños con edades y pesos gestacionales significativamente menores que anteriormente. Con el aumento de la tasa de supervivencia, cada vez más estudios se interesan por el impacto de la prematuridad en el neurodesarrollo de niños nacidos a las 37 semanas de gestación o incluso antes. En efecto, los estudios realizados hasta este momento indican que los niños prematuros tienen alto riesgo de presentar problemas de orden cognitivo, comportamental y de aprendizaje. Los mismos pueden mantenerse hasta la edad escolar e incluso hasta la adolescencia y la edad adulta. Esta revisión de la literatura tiene por objeto presentar los distintos problemas cognitivos, comportamentales y de aprendizaje documentados en estudios recientes interesados por las consecuencias de la prematuridad. Palabras clave: Prematuridad; cognición; comportamiento; problemas de aprendizaje. ResumoNascimentos pré-termo (≤ 37 gestational weeks) tem sido identificados como uma das causas mais importantes de mortalidade perinatal em sociedades industrializadas. Com a melhoria dos serviços pré-peri-e pós-natais, atualmente é possível salvar estas crianças com significativos baixos peso e idade gestacional. Frente às crescentes taxas de sobrevivência, cada vez mais estudos abordam o impacto da prematuridade no neurodesenvolvimento de crianças nascidas até 37 semanas de gestação. Pesquisas até então sugerem que crianças prematuras apresentam alto risco de dificuldades cognitivas, comportamentais e de aprendizagem, sendo que estas últimas podem se prolongar até a idade escolar, mantendo-se até mesmo na adolescência e/ou vida adulta. Esta revisão visou a identificar tais dificuldades em investigações recentes sobre as consequências da prematuridade. Palavras-chave: Prematuridade; cognição; comportamento; dificuldades de aprendizagem. AbstractPreterm births (≤ 37 gestational weeks) have been identified as one of the most important cause of perinatal mortality in industrialized societies. With improvement in pre-peri-and post-natal care, it is now possible to save these children at significantly lower weight and gestational age than previously. With increasing survival rates, more and more studies address the impact of prematurity on the neurodevelopmental outcomes of children born at or before 37 weeks of gestation. Studies to date indicate that children born prematurely are at high risk of experiencing cognitive, behavioural and learning problems, and that the latter can last up to school age and even into adolescence and/or adulthood. The aim of this review is to identify the various cognitive, behavioural and learning difficulties documented in recent studies investigating the consequences of prematurity.

“…Preterm children are at risk of a number of visual impairments, including difficulties with visual acuity (VA) 9 (1-3), contrast sensitivity (CS) (4,5), stereopsis (3,4), and visual perception (1,6,7), all skills that are important for a range of more complex and adaptive visual tasks such as classroom learning and overall school performance (8,9). Brain injury (10)(11)(12), retinopathy of prematurity (13)(14)(15)(16), and oxygen therapy during the neonatal period (17) have been reported to be associated with visual impairments, but other factors such as specific nutrients and agents that might optimize ocular and cortical development require further exploration.…”

Background: Children born preterm are at risk of visual-processing impairments. Several lines of evidence have contributed to the rationale that docosahexaenoic acid (DHA) supplementation of preterm infants may improve outcomes in visual processing. Objective: The aim was to determine whether at 7 y of age children who were born very preterm and who received a high-DHA diet have better visual-processing outcomes than do infants fed a standard-DHA diet.Design: This was a follow-up study in a subgroup of children from a randomized controlled trial. Infants were randomly assigned to milk containing a higher concentration of DHA (1% of total fatty acids; high-DHA group) or a standard amount of DHA (0.2-0.3% of total fatty acids as DHA; control group). The randomization schedule was stratified by sex and birth weights of ,1250 or $1250 g. A total of 104 (49 in the high-DHA group and 55 in the standard-DHA group) children aged 7 y were assessed on a range of visual-processing measures, including visual acuity, contrast sensitivity, vernier acuity, binocular stereopsis, and visual perception. Results: There was no evidence of differences between the high-DHA and standard-DHA groups in any of the visual-processing measures. In the majority (12 of 13) of variables assessed, the direction of effect favored the control group. The study was large enough to detect a moderate treatment effect, if one truly existed. Conclusion: Supplementing human milk with DHA at a dose of w1% of total fatty acids given in the first months of life to very preterm infants does not appear to confer any long-term benefit for visual processing at school age. This trial was registered at anzctr.org/au as ACTRN12606000327583.Am J Clin Nutr 2016;103:268-75.
