Findings
Preseptal Soft tissues and Orbital Adnexa
The preseptal soft tissues are swollen/edematous. There is no definite abnormal air collection in the preseptal soft tissues. There is postseptal air.
There is no foreign body in preseptal areas of soft tissue swelling; however, there is an approximately 3 mm area in the post-septal soft tissues, suggesting the presence of a foreign body and/or a focus of hemorrhage.
There is a tract of air along the medial orbital wall between the superior oblique and medial rectus muscles supporting a likely penetrating injury.
Eyes and Optic nerves
There is proptosis is on the left side but the optic sheath/nerve does not have a stretched appearance and there are no signs of tension orbit.
The anterior segment structures of the eye are normal. There is no evidence of a subretinal, subchoroidal, subhyaloid or intravitreous hemorrhage or other fluid collection. The junctions of the optic sheath/nerve and eye are normal and there is no evidence of hemorrhage in or along the optic nerve and/or sheath.
Orbits
There is an abnormal air collection in the postseptal extraconal and intraconal orbital compartments likely due to a penetrating injury. The extraconal and intraconal orbital fat are edematous mainly medially and back to the orbital apex. Blood products may be present. The superior oblique and medial rectus muscles are swollen and there is abnormal soft tissue swelling, extending to the orbital apex and superior orbital fissure.
The bones of the orbit including the optic canal are normal.
Brain
No There are no intra-axial or extra-axial abnormalities of the brain that might be related to the eye/orbital pathology.
