（43）垂直移動視に就いて

Vertical Locomotopsia

　固視した物体が，それ自身は静止しているに拘わらず，一定の方向へ動いて行く様に感ぜられる現象を，私は移動視と呼び，前後方向に移動するものを，矢状移動視，水平方向に移動するものを，水平移動視とした。今回は垂直方向に移動すると訴えたもの，即ち垂直移動視に該当する3症例に就いて述べることとする。

I had reported the phenomenon that a stared target which moves toward or backward should be called sagittal Locomotopsia and the one which horizontally moves should be named horizontal Locomotopsia.

For this time I described three clinical cases with the same phemomenon of vertical movement. The cases are boys of six, ten and fifteen years old. The one of them can be regarded to be attributed to hysteria and the rest of them to a blow by Karate-chop at the side of the neck during playing prowrestling.

I think it is most suitable for the phenomenon to be called vertical Locomotopsia.
