根据眼眶Lemke八分区法,将眼眶分为眶隔前区、骨膜下区、肌锥外区、肌锥区、肌锥内区、泪腺区、眼球区及视神经鞘区等 8 个区域。
眶隔前区是指位于眼眶眶隔前方的区域,主要包括眼睑;
肌锥区是指眶隔后 4 块眼直肌的区域;
视神经鞘区包括视神经及其鞘膜;
肌锥内区是指视神经鞘区与肌锥区之间的区域;
肌锥外区是指肌锥区与眶骨膜之间的区域;
骨膜下区是指眶骨膜与眶骨之间的潜在间隙;
眼球与泪腺分别称为眼球区、泪腺区。
The muscle cone, a connection between the four rectus muscles, divides the orbit into the intraconal and extraconal compartment. The optic nerve passing the central part of the intraconal compartment is, as with the rectus muscles themselves, a separate compartment. The outer limit of the extraconal compartment is the bony orbit, followed by the subperiosteal compartment.The lacrimal gland and the globe are separate compartments. The ventral border of the extraconal compartment is the orbital septum, the upper and lower lids are the anteriorly neighboring compartment.
