Abstract

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 refence 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.

    Visual deficits in this group are often associated with ROP (O’Connor et al., 2002) or major focal lesions affecting cortical and sub-cortical regions (Cioni et al., 1996, 2000; Eken et al., 1996; Fazzi et al., 2004). However, preterm infants without apparent ocular or brain lesions have a higher incidence of abnormalities, both in linear acuity and stereopsis, than infants born at term (Jongmans et al., 1996) and the underlying cause of impaired visual function in these infants in not known. In this study, only 2 infants had ROP.
