摘要
眼外肌及其筋膜组织共同维持眼球运动。既往斜视研究中更多地关注于眼外肌肌纤维的病理学变化特点，对眼外肌筋膜组织解剖及其功能认识相对较少。Pulleys是位于眼球赤道部附近与眼眶壁相连的一种弹性组织结构，直肌穿过该结构到达巩膜附着点，其限制眼外肌在眶内的滑动，是直肌运动的功能性起点，筋膜组织在眼球运动中发挥着更为主动的作用。Pulleys随着年龄增长可出现退行性变化，Pulleys异常与眼球运动障碍有关。在斜视诊断、手术设计以及结果评估中，斜视手术医生应充分考虑到Pulleys的存在。
Extraocular muscles and orbital fascia tissue cooperate in ocular motility. Previous stud- ies have mainly focused on the pathological changes of extraocular muscle fibers, rarely on the role of orbital fascia tissue in ocular motility. Pulleys is a resilient structure located near the orbital wall and connected to the equator of the eyeball, the rectus muscle reaches its sclera attachment through the structure. Pulleys con- trois the extraocular muscle （EOM） path and serves as the EOM＇s functional origin. Orbital fascia tissue plays more active role in ocular motility. Age-related degenerative changes of Pulleys can occur and abnormal Pulleys is related with the ocular motility disorders, which should be fully taken into account by the surgeons in the diagnosis and treatment of strabismus.
