Background
- Also known as retrobulbar hematoma
- Most often due to blunt orbital trauma
- Can also be 2/2 spontaneous bleeding
- Can cause loss of vision due to abrupt increase in intraocular pressure → orbital compartment syndrome (OCS)
Clinical Features
- Pain
- Proptosis
- Decreased visual acuity
- Elevated IOP
- (Do not perform tonometry if globe rupture is suspected)
Diagnosis
- CT Orbit
- Ocular ultrasound[1][2][3]
- Dx of retrobulbar pathology via ultrasound is technically difficult, has not been validated in the clinical setting and false-negatives have been reported[4] - therefore, CT should remain the standard diagnostic tool for suspected retrobulbar pathology.
