Visual function of prematurely born children with and without perceptual-motor difficulties.
The relationship between visual and perceptual-motor abilities at 6 years of age was investigated in a cohort of 141 prematurely born children without cerebral palsy. Visual acuity was assessed using the Sonksen-Silver Acuity System and stereopsis with the Titmus stereo test. Perceptual motor abilities were evaluated using the Movement Assessment Battery for Children and the Developmental Test of Visual-Motor Integration. The results showed a higher incidence of abnormalities both of linear acuity and stereopsis in the study group when compared to a group of reference children. Whereas abnormalities of linear acuity were not associated with perceptual-motor difficulties, abnormal stereopsis was significantly associated with poor performance on both perceptual-motor tests. Our results suggest that infants born preterm, even in the absence of other major neurological signs, are at risk for abnormal visual function and perceptual-motor difficulties. As these could interfere with everyday life and school performance, a longitudinal assessment of both areas of competencies is recommended so that diagnosis and possible intervention can take place as early as possible.
