这方面争论很多,目前关于发病机制的看法主要来自临床观察。关于眼外肌运动生理,有许多不同见解,尤其对于垂直直肌和斜肌的作用,意见迄今尚不一致。但明显的是:眼球在垂直方向上的运动,系由两个上举肌(上直、下斜)渐次地收缩,和两个下降肌(下直、上斜)渐次地共动地抑制所形成。各水平转动肌则维持原始位置时的收缩状态。上直肌为外转位置的主要上举肌,而内转时则主要为下斜肌。前者在原始位置为更有效的上举肌。向正上方转动时,上直肌与下斜肌就垂直运动而言,为协同肌,但就其辅助的转动及旋动而言,则互为颉抗肌。在正常情况下,此种颉抗作用能巧妙地互相平衡。
Many controversies in this regard, the current view on the pathogenesis mainly from clinical observation. There are many different opinions about the movement physiology of extraocular muscles, especially for the effects of vertical rectus and oblique muscles, which have so far not been reconciled. However, it is obvious that the movement of the eyeball in the vertical direction is gradually reduced by two upper lifting muscles (upright and downwards inclined), and the two down muscles (lower straight and diagonal) form. The level of muscle rotation to maintain the original position of the contraction state. The upper rectus abdominus position for the main lift on the outside, while the main transfer when the lower oblique. The former in the original position for more effective on the lift muscle. To the top of the rotation, the upper rectus and inferior oblique muscle in terms of vertical movement, as the synergistic muscle, but its auxiliary rotation and rotation, the mutual Jiejie muscle. Under normal circumstances, this antagonistic effect can skillfully balance each other.
