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.
我们通过在眼球后方垂直于肌锥的平面进行计算机断层扫描（CT），研究了眼球处于不同注视位置时直肌的侧向移位情况。我们发现，上视或下视时水平直肌以及左视或右视时垂直直肌均无一致的侧向移位。然而，我们发现收缩和舒张的肌肉存在明显移位。因此，我们在通过内直肌和外直肌的水平平面进行了CT扫描，结果发现，在眼球处于原位时，直肌走行呈曲线状。肌肉舒张时该曲线的曲率增加，肌肉收缩时则减小。
