title: Ultrasonographic measurement of upper eyelid thickness in Korean children with epicanthus.
abstract: OBJECTIVE
  Upper eyelid thickness was measured to determine whether there is a difference in the thickness of the upper eyelids in children with and without epicanthus.
  
  
  METHODS
  Children were enrolled into the epicanthus group or non-epicanthus (control) group. The children with epicanthus were classified into four subgroups according to the Duke-Elder's classification. The thickness of the upper eyelid was measured at five points with A-scan ultrasonography.
  
  
  RESULTS
  There was no significant difference in upper eyelid thickness between the epicanthus group and control group (P > 0.05) or between the subgroups of the epicanthus group (P > 0.05).
  
  
  CONCLUSIONS
  This result suggests that the etiology of epicanthus may not be hypertrophy of soft tissue.
