AB  - BACKGROUND: Preterm infants are more likely to develop visual perceptual and 
      visual-motor impairments. Visual perceptual deficiencies may contribute to 
      significant difficulties in daily life, but few reports are available relating 
      electrophysiological assessment of the visual system to spatial information 
      problems in premature preschoolers with average intelligence quotients. AIM: This 
      study was designed to investigate preterm preschoolers' responses to various 
      spatial frequencies of pattern reversal visual evoked potential (PRVEP) and 
      compare them to normal children. DESIGN: Participants were 20 very low birth 
      weight (VLBW), 41 low birth weight (LBW) and 41 normal children who were 4 to 6 
      years old and were free from major disability and developmentally appropriate for 
      gestational age at birth. They were evaluated using the Chinese population 
      adaptation of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) 
      and recorded PRVEP at five levels of spatial frequency (checkerboard pattern 
      (check) sizes of 108', 54', 27', 13' and 7') using a VikingQuest-IV 
      neuroelectrophysiological device (Nicolet, Madison, WI, USA). RESULTS: Compared 
      with normal children, the LBW and VLBW groups had significantly lower level in 
      the tests of verbal, performance and overall intelligence quotients, particularly 
      in performance, although the levels were within the average range. The PRVEP P100 
      wave latencies were significantly prolonged at all five degrees of spatial 
      frequency in the VLBW group compared with the controls, while showing delay in 
      the LBW with 13' and 7' check size. In the meanwhile, the amplitudes of P100 at 
      all five spatial frequencies were significantly smaller in the VLBW and LBW 
      groups than in the normal children. And VLBW group had even lower P100 amplitudes 
      than the LBW group. CONCLUSIONS: Preterm preschoolers with average cognition 
      capability are at risk of defect in visual-spatial perception, especially when 
      they are confronted with more complicated information. PRVEP may provide an 
      objective and convenient measurement in detecting the problem of visual 
      perception in children.
