The test of motion perception of the normal Chinese subjects

摘要

Conclusions The characteristic of MP of the normal Chinese subjects was determined and the re- sults provided the normal reference values. Objective To investigate the characteristic of Motion (MP) of normal Chinese subjects. Methods MPs were recorded form 56 normal Subjects (112 eyes), age ranged form 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 in- creased in the 2 pixels (2P) horizontal motion, and the MP rates were decreasing gradually over 40 age- group, and the MP rates wee not affected by the age in the 4 pixels (4p), 6 pixels (6p) horizontal motion and>40 Hz flick motion.
