Background

Eye anatomy.

Clinical Features

Corneal Abrasions from Airbag Deployment
Corneal Abrasions from Airbag Deployment
  • Foreign body sensation
  • Photophobia (+/- consensual)
  • Decreased vision
    • If associated iritis or if abrasion occurs in visual axis
  • Eye pain
    • Relief of pain with topical anesthesia
      • Virtually diagnostic of corneal abrasion

Differential Diagnosis

Unilateral red eye

^Emergent diagnoses
^^Critical diagnoses

Evaluation

  • A complete eye exam should be conducted
  • Eyelid Exam
    • Flip upper lid and exam lower lid for foreign body
    • If concern for foreign body despite normal exam, consider orbital CT or MRI if certain foreign body is nonmetallic
  • Fluorescein Exam
    • Apply 1 gtt of flourescein or use strip with anesthetic
    • Use Wood's lamp or slit lamp with cobalt blue light
    • Fluorescein will fill corneal defects and glow
    • Multiple vertical abrasions suggests foreign body embedded under the upper lid
  • Topical anesthetic (ie proparacaine or tetracaine) may assist in patient cooperation with exam once open globe excluded.
    • Repeated doses or Rx for topical anesthesia is controversial given concerns for impaired healing

Additional Considerations

  • Contact lens wearer
    • If white spot or opacity on exam concerning for infiltrate or Corneal ulcer refer for same day ophtho appt
  • Fluorescein Examination
  • Visual acuity
    • If poor, consider corneal edema versus infectious infiltrate
  • Pupil shape and reactivity
    • Irregular or nonreactive pupil suggests pupillary sphincter injury and possible penetrating trauma
  • Hyphema or hypopyon
    • Hyphema suggests possible penetrating injury
    • If present then same same-day ophtho consult is required
  • Extruded ocular contents
    • If yes then place eye shield and obtain emergent ophtho referral
  • Corneal Ulcer
    • Grayish white lesion
    • Worsening symptoms >1day

Corneal abrasion vs. corneal ulcer

Characteristic Corneal abrasion Corneal ulcer
History *Acute pain immediately after injury *Delayed pain frequently 2-3 days or more after initial event
Lesion viewable on fluorescein exam *Yes *Yes
Lesion viewable on white light exam *No *Yes
Lesion morphology *Frequently linear, punctate, patterned, and/or irregular *Commonly circular

Management

Antibiotics

Does Not Wear Contact Lens

Wears Contact Lens

Antibiotics should cover pseudomonas and favor 3rd or 4th generation fluoroquinolones

  • Levofloxacin 0.5% solution 2 drops ever 2 hours for 2 days THEN q6hrs for 5 days OR
  • Moxifloxacin 0.5% solution 2 drops every 2 hours for 2 days THEN q6hrs for 5 days OR
  • Tobramycin 0.3% solution 2 drops q6hrs for 5 days OR
  • Gatifloxacin 0.5% solution 2 drops every 2 hours for 2 days THEN q6hrs for 5 days OR
  • Gentamicin 0.3% solution 2 drops six times for 5 days

Pediatric

Same topical regimens as adults

  • Erythromycin 0.5% ointment applied QID x 3-5 days (preferred in young children)
  • Moxifloxacin 0.5% ophthalmic solution 1-2 drops QID x 5 days

Analgesia

  • Systemic NSAIDs or opioids
  • Cycloplegics can be consider for patients with large abrasions (>2mm) and/or severe pain
  • Ophthalmic NSAIDs
  • Topical anesthetics
    • Tetracaine 1% 1 drop q30min has been found to be safe in the first 24 hrs[1]
    • Proparacaine 0.05% ophthalmic (dilute 1 mL of proparacaine 0.5% with 9 mL of NS in flush syringe then place 3 mL in bottle) 1-2 drops in eye Q30 min PRN pain for 24-48 hours only[2]

Other


Medication Dosing

Cyclopentolate 1 drop 1% q6-8hr Topical ophthalmic Ketorolac 1 drop 0.4% q6hr x 2-3 days Topical ophthalmic Tetracaine 1 drop 1% q30min x 24hr Topical ophthalmic

Disposition

  • Ophtho follow up in 48h for routine cases
  • Minor abrasions will heal in 48-72h
