摘要眼眶结缔组织在眼球运动中发挥重要作用,其随年龄增长发生退行性改变,这种变化能够引起眼球控制眼外直肌运动的Pulley结构的位置发生改变,从而引起某些特殊类型的斜视发生,即“松眼综合征”,包括分开功能不足性内斜视及小度数的垂直斜视.眼眶磁共振检查发现其产生与眼外直肌Pulley位置的退行性改变有关.对于松眼综合征产生的不同类型的斜视,其治疗方法及手术方式不同,对于分开功能不足性内斜视,临床上既有内直肌后退手术,也可采用外直肌缩短手术,而对于小度数的垂直斜视,则可采用不同程度的垂直肌部分切除术.

abstractsOrbital connective tissue plays an important role in eye movements.Its degenerative change along with the aging change can cause change of pulley position,which controls the extraocular rectus muscle movement in human eyes,leading to some special types of strabismus,namely " sagging eye syndrome",including divergence insufficiency esotropia or divergence paralysis esotropia,and the occurrence of a small degree of vertical strabismus or cyclovertical strabismus.Orbital magnetic resonance imaging examination revealed that the occurrence was related to the Pulley location degeneration of extraocular rectus muslces.The treatment and surgery of the strabismus caused by orbital connective tissue degeneration is different.Either medial rectus muscle recession or lateral rectus resection is adopted for divergence paralysis esotropia,but different degree partial tenotomy of vertical rectus muscles for treatment of hypertropia is employed.
