Question 8

How to diagnose/manage retrobulbar hematoma

Answer 8

severe pain, proptosis, subconjunctival hemorrhage, and loss of vision. Imaging is not required and in most situations not recommended due to the the delay in treatment. If diagnosis is suspected but the clinician is not certain, measuring intraocular pressures can provide clues to the diagnosis. An intraocular pressure greater than 20 mm Hg is abnormal, with a value greater than 30 mm Hg being worrisome. Intraocular pressure greater than 40 mm Hg is considered an indication for an emergency lateral canthotomy
