SAEM Clinical Image Series: Eye Injury

eye

An 11-year-old male presented to a pediatric trauma center following a motor vehicle collision (MVC). He was the restrained front-seat passenger when his vehicle was struck head-on, causing frontal airbag deployment. His primary complaint was pain around his right eye with associated blurry vision. He denied diplopia, pain with extraocular movements, flashers, floaters, or curtains in his vision.


HEENT:

  • Superficial abrasions to the right periorbital area with mild upper-eyelid edema
  • Textured honeycomb pattern overlying 80 percent of the right cornea visible on direct visualization and more prominent with fluorescein staining under ultraviolet light
  • Pupils equal, round, and reactive to light, 3 mm in size
  • Bilateral visual fields intact to confrontation

Visual Acuity: Right eye 20/100, left eye 20/20

Intraocular Pressure: Right eye 12 mm Hg, left eye 18 mm Hg

Corneal pH: Right eye 7, Left eye 7

Airbag trauma

While the use of airbags has long been associated with a reduction in MVC mortality, the incidence of ocular-related airbag trauma has been well described in ophthalmologic literature [1-6]. Airbag-related injuries include alkali burns, lens dislocation, corneal abrasions, traumatic cataracts, globe rupture, and others.

Most modern airbags are equipped with a nylon bag that deploys upon vehicle impact and can cause significant facial injury. This is the likely cause of the textured honeycombed corneal abrasion in our patient described above. Airbag-related eye injuries have been found to be exceedingly rare when the vehicle occupant survives the incident and a restraint system was used appropriately [7].

 

The patient was treated with erythromycin ointment and moxifloxacin eye drops and discharged home with directions for a prompt outpatient ophthalmology follow-up.

Take-Home Points

  • In trauma patients with eye complaints following an MVC with airbag deployment, a high index of suspicion should be maintained, and a thorough ocular examination conducted.
  • Remember to check the corneal pH as alkali-related ocular injuries are potentially blinding and represent a true ophthalmologic emergency.
