Orbital compartment syndrome
|Orbital compartment syndrome|
|Retrobulbar bleeding resulting in orbital compartment syndrome|
|Specialty||Emergency medicine, ophthalmology|
|Symptoms||Decreased vision, bulging of the eye, double vision, pain, firm eye|
|Causes||Retrobulbar bleeding, infection, cancer, burns, air|
|Diagnostic method||Based on symptoms, supported by medical imaging|
Orbital compartment syndrome (OCS) is the result of rapid increase in pressure within the orbit. Symptoms may include decreased vision, bulging of the eye, double vision, and pain. The eye is typical firm to touch with a dilated non reactive pupil. Without treatment complications can include blindness.
Relatively common causes include retrobulbar bleeding due to either injury or eye surgery. Other causes include infection, cancer, burns, and air behind the eye. Diagnosis is based on symptoms, though may be supported by medical imaging in unclear cases.
Treatment is by lateral canthotomy. This should be performed as soon as the diagnosis is suspected when vision problems are present. While it is generally best for this to be performed rapidly after the onset of the condition, cases of vision recovery in delayed cases have been reported.
