eye parts
Eye Parts
  • Conjunctiva
  • Lacrimal Glands
  • Sclera
  • Pupil
  • Iris
  • Cornea
  • Lens
  • Retina
  • Optic nerve
  • Vitreous humor
  • Aqueous humor
eye injuries
Eye Injuries
  • enucleation
  • laceration
  • foreign objects
  • abrasion
  • burns
eye injuries notes
Eye injuries - notes
  • Signs can be subtle
  • Example - hyphema

(blood in anterior chamber of eye)

lacerations
Lacerations
  • Cut to the globe or surrounding tissue
  • Never exert pressure on or manipulate the eye
  • If part of eyeball is exposed, apply a moist, sterile dressing and eye shield
foreign objects in the eye
small foreign objects - irrigate with saline

Flush from the nose outward

Never attempt to remove an object on the cornea

Foreign Objects in the Eye
impaled object
Impaled Object
  • Do not remove it
  • Immobilize the object in place
  • Moist sterile dressing over the injured eye only*

*LA county

chemical burns
Chemical Burns
  • Irrigate - Irrigate - Irrigate
  • Use water or saline solution
  • 20 minutes
  • powder or liquid = irrigate
  • Dry dressing
thermal burns
Thermal Burns
  • Usually to the eyelid
  • Cover both eyes with a moist, sterile dressing and eye shield
  • Transport supine to burn center.
light burns
Light Burns
  • Infrared rays, eclipse light, direct sunlight, laser burns
  • Welding without protection
  • Burns on cornea
  • Very painful
  • Cover eyes with sterile pad and eye shield.
  • Transport supine

Not Trauma Related

  • blurred vision
  • double vision
  • sudden blindness

Think CVA or other neurological

eye injuries following a head injury
Eye Injuries Following a Head Injury
  • One pupil larger than the other
  • Eyes not moving together
  • Failure of the eyes to follow equally
  • Bleeding under the conjunctiva
  • Protrusion or bulging of one eye
contact lenses
Contact lenses
  • Leave in place unless chemical burn
  • Trying to remove them can damage cornea
  • If irrigation removes them - fine
  • If patient removes them - fine
  • If there is no function in an eye, ask if the patient has an artificial eye
ear anatomy
Ear Anatomy
  • External ear
  • Middle ear
  • Inner ear
injuries of the ear
Injuries of the Ear
  • Doesn’t usually bleed much.
  • Place a dressing between ear and scalp
  • For avulsion, moist sterile dressing.
  • Do not try to remove a foreign body
  • CSF/blood
  • Ruptured tympanic membrane
ears notes
Ears - notes
  • ringing in ears
  • sudden deafness - CVA?
  • Inner ear infections - Vertigo
nasal anatomy
Nasal Anatomy
  • Septum
  • Turbinates
  • Frontal sinus
injuries of the nose
Injuries of the Nose
  • Blunt trauma can cause fractures and soft-tissue injuries.
  • CSF/blood
  • Use dry sterile dressing for soft tissue injuries
  • Object inserted in nose can be removed if freely movable
  • Impaled objects get bulky dressing
nose bleeds
Nose Bleeds
  • Lean forward
