Orbital emphysema can be produced by trans-conjunctival migration of air from a high pressure airgun. In an industrial accident an 8 mm conjunctival laceration was produced in the superior fornix which acted as a portal of entry for air into the subconjunctival, subcutaneous, and retrobulbar spaces. Computed tomography revealed no evidence of orbital fracture and showed that traumatic orbital emphysema occurred without a broken orbital bone.
眼眶气肿可由高压气枪中的空气经结膜迁移所致。在一次工业事故中，上穹窿处出现了一个8毫米的结膜裂伤，该裂伤成为空气进入结膜下、皮下和球后间隙的入口。计算机断层扫描未发现眼眶骨折的迹象，显示外伤性眼眶气肿是在眼眶骨未骨折的情况下发生的。
