The orbit is defined as the soft tissues of the orbital cavity posterior to the orbital septum in the eyelid and includes the extraocular muscles.
The eyelid is composed of multiple layers; these are, in order from outermost to innermost, epidermis, dermis, subcutaneous tissue including a thin layer of adipose tissue, orbicularis oculi muscle, orbital septum, levator muscle, tarsal plate, Muller muscle, and palpebral conjunctiva.
If there is no improvement within a few minutes, the surgeon should consider proceeding with disinsertion of the superior canthal tendon, followed by transconjunctival or transcutaneous division of the orbital septum from its attachment to the orbital rim.
In addition, opening the orbital septum via an infraorbital approach and control of bleeding via a Lynch-type external ethmoidectomy approach should be considered.
1) The dividing line that designates an infection as either pre- or postseptal is the orbital septum and the tarsal plate that is contiguous with the periosteum of facial bone.
