To study the microscopic anatomy of the orbital septum and evaluate its relationships with the adjoined structures.
Histological evaluation of 11 upper eyelids (5 right, 6 left) from 10 Japanese cadavers (age range: 36-94-year-old, average: 71.1) was performed. The specimens were fixed in 10% formalin and stained with Elastica Van Gieson. Specimens were microscopically analyzed using different magnifications (20×, 40×, and 100×).
The orbital septum was the single fibrous layer in all the specimens, anteriorly separated from the retro-orbicularis fat pad capsule and posteriorly from the preaponeurotic fat pad capsule. At the junction of the orbital septum with the levator aponeurosis, the orbital septum proceeded towards the tarsal plate, and the preaponeurotic fat pad capsule reflected posteriorly.
The orbital septum is constituted of a single layer of fibrous tissue anteriorly separated from the retro-orbicularis fat pad capsule and posteriorly from the preaponeurotic fat pad capsule by the corresponding virtual spaces.
研究眶隔的微观解剖结构并评估其与相邻结构的关系。
对10具日本尸体（年龄范围：36 - 94岁，平均71.1岁）的11只上睑（5只右侧，6只左侧）进行组织学评估。标本用10%福尔马林固定，并用弹性纤维Van Gieson染色。使用不同放大倍数（20×、40×和100×）对标本进行显微镜分析。
在所有标本中，眶隔均为单一纤维层，前部与眼轮匝肌后脂肪垫包膜分离，后部与眶隔前脂肪垫包膜分离。在眶隔与提上睑肌腱膜的交界处，眶隔向睑板延伸，眶隔前脂肪垫包膜向后折返。
眶隔由单层纤维组织构成，前部通过相应的虚拟间隙与眼轮匝肌后脂肪垫包膜分离，后部与眶隔前脂肪垫包膜分离。
