Abstract

Orbital emphysema is radiologically apparent in 50% of cases of orbital fractures, but it is generally a benign, self-limited condition. However, visual loss may occur if a fracture produces orbital compression via a ball-valve effect, allowing air to enter but not leave the orbit. A case of compressive orbital emphysema complicated by ischemic optic neuropathy is reported. Intraorbital needle aspiration relieved the compression with improvement of visual acuity and normalization of intraocular pressure.

摘要

眼眶气肿在50%的眼眶骨折病例中放射学表现明显，但通常是一种良性的自限性疾病。然而，如果骨折通过球阀效应导致眼眶受压，使空气进入但无法离开眼眶，则可能会发生视力丧失。本文报告了一例伴有缺血性视神经病变的压迫性眼眶气肿病例。眶内针吸减压后视力改善，眼压恢复正常。
