title: The test of motion perception of the normal Chinese subjects.
abstract: OBJECTIVE
  To investigate the characteristic of motion perception (MP) of normal Chinese subjects.
  
  
  METHODS
  MPs were recorded from 56 normal subjects (112 eyes), age ranged from 11 to 68 years, and the MP software was controlled by PC compatible computer which appeared as the vertical bar targets in VGA screen.
  
  
  RESULTS
  The Mp rates were ascending gradually from 10 age-group to 30 age-group as the age increased in the 2 pixels (2P) horizontal motion, and the MP rates were decreasing gradually over 40 age-group, and the MP rates were not affected by the age in the 4 pixels (4P), 6 pixels (6P) horizontal motion and > 40 Hz flick motion. There was no relation between the MP and the sex and the different eyes.
  
  
  CONCLUSIONS
  The characteristic of MP of the normal Chinese subjects was determined and the results provided the normal reference values.
