我们通过在垂直于眼球后方的肌锥的平面上进行计算机断层扫描 (CT) 扫描，研究了眼睛在不同注视位置时直肌的侧向位移。我们发现，向上或向下凝视时的水平直肌或向左或向右凝视时的垂直直肌没有一致的侧向位移。然而，我们发现收缩和放松的肌肉发生了很大的位移。因此，我们在水平面上通过内侧和外侧直肌进行 CT 扫描，发现当眼睛处于主要位置时，直肌遵循弯曲的路径。路径的曲率随着肌肉放松而增加，随着肌肉收缩而减小。
We investigated the sideways displacement of recti muscles with the eye in various gaze-positions by making computed tomographic (CT) scans in a plane perpendicular to the muscle cone, posterior to the globe. We found no consistent sideways displacement of the horizontal recti in the up or down gaze or the vertical recti in the left or right gaze. We found a substantial displacement, however, of the contracting and relaxing muscles. Consequently, we made CT scans in a horizontal plane through medial and lateral recti and found that, with the eye in primary position, the recti muscles follow a curved path. The curvature of the path increased following muscle relaxation and decreased following muscle contraction.
