Objective: To investigate the neurodevelopmental outcomes in children with developmental disorder according tovisual evoked potential (VEP) results.
Methods: We retrospectively analyzed children who visited our Department of Pediatric Rehabilitation Medicinewith a chief complaint of developmental disability from January 2001 to July 2015. Of the 549 medical recordsreviewed, 322 children younger than 42 months who underwent both Bayley Scales of Infant and ToddlerDevelopment second edition (BSID-II) and VEP studies were enrolled. We compared the development of 182children with normal VEP latency and 140 children with delayed VEP latency results using the BSID-II results. TheMann-Whitney U-test was used to analyze the differences between the two groups.
Results: There were no significant differences in baseline characteristics between the two groups. The delayedVEP latency group showed a significant delay in BSID-II index scores and developmental quotients comparedwith the normal VEP latency group. In addition, a comparative analysis of developmental quotients of mental andpsychomotor domains according to age (younger than 12 months, 12?23 months, and 24?42 months) revealedsignificantly lower values in children with delayed VEP latency compared to children with normal VEP latency,younger than 12 months and from 12 to 23 months.
Conclusion: Children with delayed VEP latency showed more developmental delay than children with normalVEP latency. It is suggested that VEP can be easily applied to children with suspected developmental delay whenphysicians have concerns about visual impairment. Furthermore, it is proposed that VEP results could provide aninsight into children’s development and serve as early indicators for consultation with an ophthalmologist for theexisting problem.
