A CT should be ordered after performing a lateral canthotomy and cantholysis to minimize the complications associated with elevated retrobulbar pressure including ischemia and permanent loss of vision. This photograph depicts a patient who presented to the ED suffering from the effects of orbital compartment syndrome (OCS) after being punched in the eye. OCS can develop from as little as 7mL of fluid accumulation in the retro-orbital space and can rapidly lead to permanent blindness if ischemia is present for more than 100 minutes. Symptoms of OCS requiring immediate lateral canthotomy and cantholysis include: proptosis, increased intraocular pressure, Marcus-Gunn pupil, decreased acuity, or restricted ocular movements. Importantly, OCS is a clinical diagnosis, and treatment of this condition should not be delayed for further testing or diagnostic workup. While treatment may not result in the return of vision, there are many case reports of patients regaining full or partial vision up to two hours after the onset of symptoms.
