  4. History
    1. Type of work being performed at time of injury?
    2. Tools being used (e.g. high velocity power tool, hammering)?
    3. Working with metal or wood?
    4. Wearing Eye Protection at the time of the injury?
    5. Baseline Visual Acuity?
    6. Glasses or contacts use (and are contacts in the eye currently)?
  5. Exam
    1. Visual Acuity (always)
      1. Consider Topical Eye Anesthetic first if light sensitive
      2. Delay only in cases of Chemical Eye Injury (irrigation precedes acuity exam)
      3. Use Snellen Chart (if <20/200, check finger counting, hand movement, light perception)
    2. Visual fields by confrontation
      1. Defect suggests Retinal, Optic Nerve or CNS injury
    3. External eye findings
      1. Eyelid ecchymosis
      2. Proptosis
      3. Trismus suggests lateral orbital wall Fracture
      4. CN 5-2 Paresthesias suggests orbital floor Fracture
    4. Extraocular Movement
      1. Upward gaze problem suggests orbital floor Fracture
    5. Pupil exam
      1. Evaluate for pupil size and reactivity
      2. Swinging Flashlight Test
        1. Evaluate for Afferent Pupillary Defect (abnormal, Pupil Dilation in response to light)
        2. Afferent Pupillary Defect suggests a more serious Eye Injury with worse prognosis
        3. Schmidt (2008) Ophthalmology 115(1): 202-9 +PMID:17588667 [PubMed]
      3. Tear drop shaped or peaked pupil suggests Globe Rupture
    6. Eyelids
      1. Evert upper Eyelid to observe for Eye Foreign Body
      2. Sweep upper and lower Eyelids with a moistened cotton swab
    7. Fluorescein stain
      1. Corneal Epithelial Disruption (e.g. Corneal Abrasion, Corneal Laceration)
      2. Seidel Test (evaluation of Globe Rupture)
        1. Vitreous fluid leaks from eye and dilutes Fluorescein
    8. Slit Lamp Exam of Conjunctiva, Cornea and anterior chamber exam
      1. Foreign body
      2. Corneal Abrasion or Laceration
      3. Hyphema
      4. Chemosis
      5. Conjunctival injection
    9. Funduscopic Exam (Red Reflex)
      1. Altered Red Reflex suggests serious Eye Injury
    10. Other tests
      1. Intraocular Pressure testing should be avoided in suspected Globe Rupture
  6. Evaluation: Red Flags (require immediate ophthalmology evaluation)
    1. Sudden decrease in Visual Acuity
    2. Visual field defect
    3. Painful Extraocular Movements
    4. Photophobia
    5. Diplopia
    6. Proptosis
    7. Light Flashes or Floaters
    8. Pupil with irregular shape (e.g. tear drop)
    9. Hyphema
    10. Lights seen with halos
    11. Suspected Globe Rupture (e.g. broken eyeglasses)
    12. Medial canthus injury
  7. Precautions
    1. Initial poor Visual Acuity at presentation does NOT irrevocably predict Vision Loss
      1. Even those with complete Vision Loss initially, have a significant chance of regaining near normal vision
      2. May (2000) Graefes Arch Clin Exp Ophthalmol 238(2):153-7 +PMID:10766285 [PubMed]
  8. Imaging: Intraocular foreign body
    1. Orbital Ultrasound
      1. Contraindicated in Globe Rupture
      2. May help identify occult foreign body
        1. However, Exercise caution in applying pressure with probe
    2. CT Orbits
      1. First-line study for intraocular foreign body
      2. Test Sensitivity: 60-100% for identify foreign body
        1. Best efficacy for larger foreign bodies, glass, metal, stone
        2. Negative CT Orbits does not exclude foreign body
  9. Complications: Intraocular foreign body
    1. Endophthalmitis (30%)
    2. Eye enucleation (8%)
    3. Complete Vision Loss (5%)
  10. Management: Intraocular foreign body
    1. Consult ophthalmology early, emergently
    2. Ophthalmology intervention within 24 hours improves outcomes
      1. Decreased Endophthalmitis risk
      2. Improved outcome in Visual Acuity
    3. Tetanus Vaccine
      1. Broad-spectrum parenteral antibiotics to prevent Endophthalmitis
        1. Vancomycin AND
        2. Ceftazidime or Fluoroquinolone
  11. Prevention
    1. See Eye Protection
    2. Hammering is a major cause of Eye Injury (use Eye Protection!)

Eye Injuries (C0015408)

Definition (MEDLINEPLUS)

The structure of your face helps protect your eyes from injury. Still, injuries can damage your eye, sometimes severely enough that you could lose your vision. Most eye injuries are preventable. If you play sports or work in certain jobs, you may need protection.

The most common type of injury happens when something irritates the outer surface of your eye. Certain jobs such as industrial jobs or hobbies such as carpentry make this type of injury more likely. It's also more likely if you wear contact lenses.

Chemicals or heat can burn your eyes. With chemicals, the pain may cause you to close your eyes. This traps the irritant next to the eye and may cause more damage. You should wash out your eye right away while you wait for medical help.

Definition (NCI) Damage to the eye.
Definition (MSH) Damage or trauma inflicted to the eye by external means. The concept includes both surface injuries and intraocular injuries.
Definition (CSP) damage or trauma inflicted to the eye by external means including both surface injuries and intraocular injuries.
