We write about an interesting article by Zaggut et al

, that was published in your journal. We wondered what the authors’ opinions are regarding
the concept of the thin orbital floor and medial orbital wall being akin to a biological
orbital “crumple zone.” The orbit has a pyramidal shape with a wide base and narrow
apex.

Ordinarily, forcing the globe into the orbit would increase orbital pressure as the
globe moves posteriorly into a smaller space. Subsequently, the medial orbital wall
or orbital floor would preferentially fracture before the intraocular pressure increased
to levels that might cause the globe to rupture. As recommended by the authors, fixation
for second-time orbital fracture repair may preclude this evolutionary and protective
anatomical mechanism.To read this article in full you will need to make a payment
