WWWTP #10 Answer…

September 22, 2013


This patient came in with trauma to the face after an altercation, here was his head CT:


The patient’s left eye is somewhat proptotic in comparison to the right and he has high density fluid consistent with blood in the retrobulbar space.  This is a retrobulbar hemorrhage.  Turns out clinically he had a proptotic eye, intraocular pressures were 27 and he was having difficulty seeing.  After a lateral canthotomy and cantholysis his vision returned, his pressures dropped to the low 20s.  Here is the rest of his CT imaging:

What is even more interesting about this patient is that he had a inferior orbital wall blowout fracture.  The retrobulbar space should be communicating with the maxillary sinus (as you can see there is a lot of blood in the sinus as well) and orbital compartment syndrome usually doesn’t occur with these type of fractures.
