Coronal computerized tomographic scans of 25 patients were reviewed in order to determine the normal relationship of rectus muscles to the globe. Using a horizontal reference line constructed along the anterior cranial fossa, the mean horizontal rectus muscle axis was found to be slightly excyclotorted in both eyes, and the mean vertical rectus muscle axis slightly incyclotorted in both eyes. In addition, the mean superior temporal quadrant angle formed by the intersection of the horizontal and vertical rectus muscle axis was significantly greater than the mean superior nasal quadrant angle in the same eye. The presence of large anatomical variations in individual patients may make it difficult to implicate rectus muscle malposition as an important etiology of A- and V-pattern strabismus.
回顾了25例患者的冠状位计算机断层扫描，以确定直肌与眼球的正常关系。沿着前颅窝构建一条水平参考线，发现双眼的水平直肌平均轴均有轻微外旋转，双眼的垂直直肌平均轴均有轻微内旋转。此外，同一眼内水平直肌轴与垂直直肌轴相交形成的颞上象限平均角度明显大于鼻上象限平均角度。个体患者存在较大的解剖变异，可能难以将直肌位置异常视为A-和V-型斜视的重要病因。
