Study on the velocity of saccadic eye movements

The velocity of eye movements can be measured by using the corneo-retinal potential of the eyeball. This potential is changed almost in proportion to the eccentricity of the eyeball, and we analyze the detailed motion of the eyeball. Particularly, we measured the velocity of the horizontal saccadic eye movements. Then, we obtained the useful results by investigating experimentally the velocity difference between left eyeball and right eyeball in such following cases. When both eyeballs are opened, the velocity of the adduction is faster than the velocity of the abduction. When one eyeball is covered, the velocity of the covered eyeball is faster than the velocity of the opened eyeball.
