We examined the patients clinically diagnosed as congenital superior oblique palsy with magnetic resonance imaging. Patients who had atrophic superior oblique muscle showed larger horizontal and vertical deviation than patients with normal volume of superior oblique muscle. The patients who had atrophic superior oblique muscle required more muscles to be operated than the patients with normal volume superior oblique muscle. We proposed a new surgical algorithm, and we showed the effectiveness of the algorithm. The eyes with atrophic superior oblique muscles had higher risk of astigmatism and treatment of amblyopia was more often required. Forced traction testing of superior oblique tendon correlated with imaging study.We studied the relationship between superior oblique muscle atrophy and facial asymmetry utilizing cephalometric x-ray. There was no relationship between bony anomaly of face and the volume of superior oblique muscle. The facial asymmetry does not seem to be the cause of superior oblique muscle atrophy but the result.We examined the eye movement on the patients with third nerve palsy, and who underwent excision of the lateral rectus muscle. After the surgery, the eye still moved laterally, which suggested the existence of connective tissue between the eye ball and extra ocular muscle.We performed contralateral rotation of eye after macular translocation surgery with 3 60-degree retinotomy. The eye was rotated 10-35 degrees, but the position of extra ocular muscles in orbit did not change. This finding suggests, that extra ocular muscles are strongly connected to the orbit by pulley structure.

我们对临床诊断为先天性上级斜肌麻痹的患者进行磁共振检查。上级斜肌萎缩患者的水平和垂直偏斜均大于上级斜肌体积正常的患者。上级斜肌萎缩患者需要手术的肌肉数量多于上级斜肌正常者。我们提出了一种新的手术算法，我们证明了算法的有效性。上级斜肌萎缩的患眼有较高的散光风险，更常需要弱视治疗。通过上级斜肌肌腱牵引试验与影像学研究相结合，利用X线头影测量研究了上级斜肌萎缩与面部不对称的关系。面部骨性异常与上级斜肌的体积无关。面部不对称似乎不是上级斜肌萎缩的原因，但结果。我们检查了眼运动的第三神经麻痹的病人，谁接受了外直肌切除。手术后眼球仍向外侧移动，提示眼球与眼外肌之间存在结缔组织。眼球旋转10-35度，但眼眶中额外眼肌的位置没有改变。这一发现表明，额外的眼肌通过滑轮结构与眼眶紧密相连。
