RT Journal Article SR Electronic T1 Orbital blowout fracture from nose blowing JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2018-224633 DO 10.1136/bcr-2018-224633 VO 2018 A1 Sam Myers A1 Daniel Bell YR 2018 UL http://casereports.bmj.com/content/2018/bcr-2018-224633.abstract AB Orbital blowout fractures are nearly always caused by acute trauma. Non-traumatic cases of orbital blowout fractures have only been rarely described. In this case study, we discuss an orbital blowout fracture directly caused by nose blowing. The patient developed unilateral eye swelling and orbital emphysema. It is important for the clinician to investigate all suspected orbital blowout fractures with imaging and full ophthalmological examination regardless of a trauma history. Most cases of orbital emphysema resolve spontaneously, however one must always exclude compression of the central retinal artery. This may present as acute loss of vision and/or ophthalmoplegia.
