Area of Science:

  • Ophthalmology
  • Trauma Surgery
  • Emergency Medicine

Background:

  • Orbital barotrauma is an uncommon injury.
  • Industrial suction devices can cause facial trauma.
  • Understanding rare injury mechanisms is crucial for diagnosis and treatment.

Observation:

  • A 24-year-old man experienced orbital and facial injury from an industrial suction device.
  • Clinical signs included proptosis and restricted ocular motility.
  • Computed tomography confirmed orbital soft tissue hemorrhage and edema.

Findings:

  • The injury mechanism involved a sudden decrease in extravascular atmospheric pressure.
  • Findings mimicked conditions associated with increased intravascular pressure.
  • Absence of retinal hemorrhages and exudates differentiated it from Purtscher's retinopathy.

Implications:

  • This case expands the understanding of orbital barotrauma.
  • It highlights the importance of considering barometric pressure changes in orbital injuries.
  • Physiological similarities to other pressure-related syndromes warrant further investigation.
