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.
眼眶爆裂性骨折几乎总是由急性外伤引起。非创伤性眼眶爆裂性骨折的病例鲜有报道。在本病例研究中，我们讨论一例因擤鼻直接导致的眼眶爆裂性骨折。患者出现单侧眼部肿胀和眼眶气肿。对于临床医生而言，无论有无外伤史，对所有疑似眼眶爆裂性骨折的患者进行影像学检查和全面的眼科检查都很重要。大多数眼眶气肿病例可自行缓解，然而必须始终排除中央视网膜动脉受压的情况。这可能表现为急性视力丧失和/或眼肌麻痹。
