Signs and Symptoms!!navigator!!

History

  • Direct trauma to the globe
  • Known or potential foreign body
  • Contact lens use
  • History of previous corneal abrasion
  • Ocular/periocular surgery
  • Pre-existing visual impairment
  • Time of onset
  • Associated symptoms or concomitant injury
  • Treatment before visit
  • Occupational risks: Use of safety glasses (pounding, drilling, grinding metal) or eyeglasses
  • Systemic disease (diabetes, autoimmune disorders)
  • Tetanus status
Pediatric Considerations
  • Signs and symptoms may differ:
    • Excessive crying
  • Younger than 12 mo:
    • Frequently no history of eye trauma
    • Might present as the crying inconsolable infant
    • In 1-12 wk old may be an incidental finding and not the cause of their irritability or crying
  • Older than 12 mo:
    • More often will have history of minor eye trauma
    • Positive eye signs

Physical Exam

  • If indicated, evaluate for other life-threatening injuries with attention to the primary survey
  • Complete eye exam:
    • Focus is to evaluate for evidence of penetrating injury and /or infection
    • Gross visual inspection
    • Visual acuity
    • Penlight exam to evaluate for conjunctival injection, the pupil shape/reactivity, and for any evidence of corneal infiltrate or opacity
    • Evert upper lids to check for retained foreign body
    • Slit-lamp exam to evaluate for foreign body, anterior chamber reaction, infiltrate, corneal laceration, and penetrating trauma
    • Fluorescein dye to identify size and location of corneal epithelium defect
    • Application of topical anesthetic drops typically improves symptoms

Essential Workup!!navigator!!

Complete eye exam to rule out globe rupture and including visual acuity, gross inspection, and fluorescein

Diagnostic Tests & Interpretation!!navigator!!

Pediatric Considerations
Hand held slit-lamp and Wood lamp: Helpful in exam of pediatric eye

Follow-Up

[Section Outline]

Disposition!!navigator!!

Admission Criteria

Associated injuries requiring admission

Discharge Criteria

All simple corneal abrasions

Issues for Referral

No studies on optimal follow-up. Practice recommendations however dictate all corneal abrasions require follow-up to ensure healing without infection or scarring, particularly given a history of significant trauma, worsening symptoms despite treatment, infiltrate around the abrasion, recurrent erosion syndrome

Follow-up Recommendations!!navigator!!

Pearls and Pitfalls

  • Always rule out penetrating trauma to the globe
  • Diligently evaluate for evidence of infection
  • Avoid discharging the patient with any topical anesthetic
  • Do not use a mydriatic agent on a patient with a history of glaucoma
  • Advise against contact use until cleared by ophthalmology
