AbstractOrbital 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.
