Bilateral orbital emphysema from compressed air injury

Area of Science:

• Ophthalmology
• Trauma Surgery

Background:

• Automobile tire explosions can cause significant pressure waves.
• Ocular trauma from such events requires careful evaluation.

Observation:

• A 60-year-old man presented with bilateral subconjunctival air after a tire explosion.
• Ophthalmic examination revealed no conjunctival lacerations.
• Computed tomography confirmed orbital emphysema without fracture.

Findings:

• Subconjunctival air and orbital emphysema were diagnosed.
• Visual acuity initially decreased but returned to baseline within two weeks.
• Resolution of subconjunctival air occurred by the two-week follow-up.

Implications:

• Orbital emphysema can result from high-pressure air injuries.
• The absence of a visible entry site does not rule out significant injury.
• This case highlights the importance of considering emphysema in ocular trauma from pressure events.
