Abstract

Saccadic velocity was measured using Life-Tech's Visulab apparatus(saccadic velocity measuring module) in 37 healthy males aged from 24 to 25 yrs. Interfixational amplitude was 30 degrees(15 degrees left from the center and 15degree right from the center) and each fixation lamp was on for one second alternately and volunteers were instructed to fix left target for one second and then right target for one second alternately. Saccadic velocities were measured three times and these results were averaged. The mean saccadic velocity toward right and left was 578 degrees +/- 84/sec and mean saccadic velocity from right to left was 576 degrees +/- 88/sec and that from left to right was 580 degrees +/- 81/sec. There was no statisiticaly significant velocity difference between leftward and rightward velicities.
