Eighteen cases of spastic diplegia (SD) ranging in age from 5 year 4 month to 9 year
5 month with preterm birth were studied to clarify the relationship between visuo-perceptual
impairment and their cerebral lesions. All underwent neuropsychological examinations
including the Frostig developmental test of visual perception, Tanaka-Binet or Suzuki-Binet
intelligence test, and MRI examination. Cerebral lesions were detected in all subjects,
and the volume of the peritrigonal white matter of the parietal and occipital lobes
was significantly correlated with the visuo-perceptual impairment (r = 0.74, in the
axial plane; r = 0.64, in the coronal plane). We propose that visuo-perceptual impairment
is caused by cerebral lesions and that the measurement of peritrigonal white matter
by MRI is useful for detecting potential visuoperceptual impairment at an early age.
