Very preterm are at risk of cognitive and executive deficits that persist in adulthood. Mechanisms are only partly understood and current clinical methods cannot detect such problems in infancy. The purpose of the study is to investigate if early visual functioning is predictive of perceptual, cognitive, social characteristics and executive functions at 12 years of age.The LOVIS study (LOngitudinal VISual follow-up of visuomotor development) included a population-based cohort of 113 very preterm children born 2004-2007. Infants were assessed repeatedly, including visual tracking at 2 and 4 months, Bayley Scales of Infant Development at 2.5 years and Wechsler Intelligence Scale for Children at 6.5 years. The present cohort includes 104 children, of which 30 also belong to the national EXPRESS study with controls that will be used in the project.The LOVIS project at 12 years includes: 1) gaze recording and psychological/phonological assessments; 2) cerebral MRI, and 3) ophthalmological examination, salivary cortisol and motor function.Preliminary data from this unique project indicate close relationships between early visual tracking ability and neurodevelopment. Due to the range of domains assessed it will be possible to examine the relative impact of impaired visual perception as it affects different domains of cognition, behavior and motor function. Improved knowledge about these disabilities provides a starting point for effective help and training.
