Visual-perceptual impairment in children with periventricular leukomalacia

Brain Dev. 2004 Dec;26(8):506-12. doi: 10.1016/j.braindev.2004.02.002.


We set out to define visuo-perceptual impairment related to periventricular leukomalacia (PVL) using the Developmental Test of Visual Perception (DTVP). Correlations were sought between visual-perceptual deficits and DTVP profile and neuroradiological and neurophthalmological findings. The DTVP was administered to 20 children (m/f: 10/10), aged between 5 and 8 years (mean: 6.95 years), presenting with: spastic diplegia; PVL documented by brain MRI; normal or mildly impaired visual acuity; mild-moderate upper limb functional impairment. The mean General Visual-Perceptual Quotient was impaired, showing a great variability among the patients. Despite this, an uneven DTPV profile, characterised by a significant difference between the VMIQ and the Non-Motor Visual-Perceptual Quotient (P < 0.001) and a poor result on the Closure subtest (identification of whole figures from incomplete visual information) was observed in all the subjects. This profile reflects a deficit in eye-hand coordination and in praxic-constructional abilities and could be the expression of malfunctioning of the occipital-parietal pathway of visual integration, the so-called 'dorsal stream,' a hypothesis reinforced by the emergence of a statistically significant correlation between the neuroradiological data and the presence of visual-perceptual impairment.
