We present the first reported case of vision loss due to tension orbital emphysema associated with tension pneumocephalus resulting from blunt trauma. In the setting of trauma, intraorbital air indicates paranasal sinus-orbital communication. Tension orbital emphysema may cause vision loss through optic nerve compression, ischemia, or contusion; or central retinal artery occlusion. Vision impairment after craniofacial injury should prompt urgent computed tomography. Tension orbital emphysema with associated vision impairment requires treatment including direct decompression and, in some cases, high-dose steroids to preserve vision. Increases in sinus pressure from coughing, nose-blowing, or vomiting should be avoided until definitive treatment can be instituted.
我们报告了首例因钝性创伤导致的张力性气颅相关的张力性眼眶气肿引起视力丧失的病例。在创伤情况下,眶内积气提示鼻窦-眼眶相通。张力性眼眶气肿可通过视神经受压、缺血或挫伤导致视力丧失;或引起视网膜中央动脉阻塞。颅面部损伤后出现视力障碍应立即进行计算机断层扫描。伴有视力障碍的张力性眼眶气肿需要进行治疗,包括直接减压,在某些情况下,还需要使用大剂量类固醇来保护视力。在进行确定性治疗之前,应避免因咳嗽、擤鼻或呕吐导致鼻窦压力增加。
