THE TEST OF MOTION PERCEPTION OF THE NORMAL CHINESE SUBJECTS

Objective To investigate the characteristic of motion perception (MP) of normal Chinese subjects. Methods MPs were recorded from 56 normal s ubjects (112 eyes), age ranged from 11 to 68 years, and the MP softwar e was controlled by PC compatible computer which appeared as the verti cal bar targets in VGA screen. Results The Mp rates were ascending gra dually 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 gradu ally 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 flic k motion. There was no relation between the MP and the sex and the dif ferent eyes. Conclusions The characteristic of MP of the normal Chines e subjects was determined and the results provided the normal referenc e values.
