Assessment of visuoperceptual disturbance in children with spastic diplegia using measurements of the lateral ventricles on cerebral MRI.

The authors estimated perceptual disturbance in children with spastic diplegia from the difference between the visual and performance IQ scores (VIQ-PIQ) on the Wechsler Intelligence Scale for Children-Revised (WISC-R), having found a strong negative correlation between this score and the PQ obtained on the Frostig Developmental Test of Visual Perception (DTVP). The ratio of the areas of the posterior horns to the anterior horns (P/A) correlated negatively with visuoperceptual disturbance. This ratio can therefore be used to assess perceptual disturbance at an early age in children with spastic diplegia.
