| 基金项目： | 通过对两例单侧垂直后退综合征患者临床表现及核磁共振结果的分析，探讨其发病机制。对两例垂直后退综合征患者行MRI检查,运用多平面重组(MPR)技术进行多维重组,分别在沿神经长轴的层面显示眼运动神经的走行和毗邻结构。核磁共振结果显示两位患者其眼眶内异常结构均附着于眼球的颞下方且大小相似，但是两位患者的临床表现不同。连续斜冠状位核磁共振结果示患者眼眶内异常结构具有不同的起源和异常的神经支配。异常眶内组织结构和神经支配可能是导致患者上方注视时眼球后退、睑裂变小的原因。 |

| 摘 要： | 对两例单侧垂直后退综合征患者临床表现及核磁共振结果的分析，探讨其发病机制。MRI显示发自总腱环的与眼外肌等信号的条索样结构至于眼球后壁，两位患者眶内异常结构均附着于眼球的颞下方，表现出不同的斜视。连续斜冠状位核磁共振结果示两患者眼眶内异常结构起止点不尽相同，且具有可疑的异常神经支配，与患者上方注视时眼球后退、睑裂变小相关。

MRI of unilateral vertical retraction syndrome with atypical strabismus |

| Abstract: | We report two patients with unilateral vertical retraction syndrome with previously unappreciated mechanism. Magnetic resonance imaging (MRI) of the orbits of the two cases showed similar size and location of the orbital structure, but with dramatically different strabismus type. MRI sagittal reconstruction of the orbits suggested that abnormal muscle tissue arised from the inferior rectus, which might be associated with retraction and narrowing of the palpebral fissure and atypical strabismus as well. |
