Traumatic eye and intracranial air-movement from a subconjunctival to an intracranial position.

In a 12-year-old boy, air accidentally introduced subconjunctivally from the pointed tip of an air compressor hose, moved to an intracranial position over the sella turcica as demonstrated by x-ray films. The globe and a portion of the optic nerve were also outlined by air contrast. A minor corneal abrasion and traumatic iritis cleared promptly and no fractures or other damage occurred.
