**1. Introduction**

Periorbital infections are typically classified as either preseptal or orbital cellulites and are common in children and adults. One of the major anatomical structures determining the lo‐ cation of disease is the orbital septum, which is a thin membrane originating from the orbital periosteum inserting into the anterior surfaces of the tarsal plates of the eyelids. The septum separates the superficial eyelid from the deeper orbital structures, forming a barrier that pre‐ vents infection in the eyelid from extending into the orbit.
