Eye injuries
- 1.
- 2. Learning Objectives At theend of this lecture the students will be able to: • Landmarks of the eye • Different types of eye injuries • Emergency care for eye injuries • Contact lenses, and how to remove them • Dental trauma • Emergency care for dental injuries
- 3. Eye Injuries • Theglobe of the eye, or eyeball is a sphere approximately 1” in diameter • 5 most important landmarks of the eye: – Sclera – the “white” of the eye – Cornea – clear, front portion of the eye which covers the pupil. – Pupil – opening in which light enters – Iris – colored portion of the eye – Retina – back of the eye
- 4. Common causes ofeye trauma: • Blunt/penetrating trauma • – Sport/recreational activities • – Assaults • – Chemical exposures from household products • – Industrial accidents • – Foreign bodies • – Animal bites/scratches
- 5. TYPES OF EYEINJURIES • Eye injuries are usually not life-threatening • Time is of the essence in your treatment, • – to help prevent any visual disturbances and disruption • 6 different types of eye injuries: • – Foreign object in the eye • –
- 6. • Injury tothe orbits • – Lid injury • – Injury to the globe • – Chemical burn to the eye • – Impaled object/ Extruded eyeball
- 7. Foreign Object inthe Eye • Dust, dirt, sand, or fine pieces of metal can be blown or driven into the eye and lodged there • A flow of tears washes out many of these substances before any harm is done • A patient with a foreign object in the eye, will complain of feeling the object, and the globe will appear red
- 8. Emergency Care fora Foreign Object in the Eye • Flush the eye for at least 20 minutes • If you cannot flush the eye, and the object is from the white of the eye, try to remove the object • Ask the patient if they have made any attempt in removing the object – possibly causing an abrasion to the cornea
- 9. • To removethe object: • Pull down the lower lid while the patient looks up, or pull up the upper lid while the patient • looks down, remove object with sterile gauze • If unable to remove, cover both eyes with bandages
- 12. Injury to theOrbits Trauma to the face may result in the fracture of one or several bones that form the orbits of the eyes • Injuries serious enough to cause orbital fractures, may also cause a cervical spine injury
- 13. Lid Injury • Lidinjuries include bruising, burns, and lacerations • Lid injuries can cause profuse bleeding • Anything that lacerates the lid, can also cause damage to the eyeball
- 14. Emergency Care fora Lid Injury • Control bleeding with light pressure • Do not use pressure if the eyeball itself may be injured • Cover lid with sterile gauze soaked in saline to keep wound from drying • Preserve any avulsed skin, and transport it with the patient for later grafting • If eyeball injury is not suspected, cover injured lid with a cold pack to reduce swelling • Cover both eye’s to decrease movement
- 15. Injury to theGlobe • Injuries to the globe include bruising, lacerations, foreign objects, and abrasions • Globe injuries should be treated with great caution! • Emergency Care: – Apply patches to both eye’s – Do not apply pressure if you suspect a ruptured eyeball – Pressure can force the eye contents to leak out
- 16. Chemical Burn • Chemicalburns to the eye represents a DIRE emergency • Permanent damage can occur within seconds • The first 10 minutes following an injury often determines the final outcome • REMEMBER: • Burning and tissue damage will continue to occur as long as any substance is left in the eye… even if that substance is diluted
- 17. Chemical Burn Signs andSymptoms: – Irritated, swollen eyelids – Redness of the eye – Blurred/diminished vision – Excruciating pain in the eye’s – Irritated, burned skin around the eye’s
- 18. Emergency Care fora Chemical Burn • Immediately begin irrigation with water or saline – It need not be sterile, but should be clean • Hold eyelids open so all chemicals can be washed from behind the lids • Continuously irrigate for a Minimum 20 minutes • Remove contact lenses – may trap chemicals • Remove any solid particles from the surface of the eye Wash your hand’s afterward…Prevent contamination to yourself!
- 19. Irrigation of aChemical Burn
- 20. Impaled Object &Extruded Eyeball • Impaled or embedded objects in the eye should not be removed • Your job consists of stabilizing the object to prevent accidental movement or removal • NEVER attempt to replace the eye in the socket!!
- 21. Impaled Object &Extruded Eyeball Emergency Care • Immobilize the head and spine • Encircle the eye and impaled object/extruded eyeball with a gauze dressing • Do Not apply pressure! • Stabilize embedded object with a cup or dressings – Impaled object/extruded eyeball should not touch the sides, or the top of the cup * Make sure to bandage both eyes to prevent movement
- 22. Stabilizing an ImpaledObject & Extruded Eyeball
- 23. Contact Lenses • Eyeinjuries are often complicated by the presence of contact lenses • To detect lenses, shine a pen light into the eye – A soft lens will show up as a shadow on the outer portion of the eye – A hard lens will show up as a shadow over the colored portion of the eye (iris) • Some patient’s only wear contact lenses in one eye, so make sure to check both eyes • Some patient’s wear both contact lenses and eye glasses (elderly) • You should remove contact lenses if there is a chemical burn to the eye • Do Not remove contact lenses if the eyeball is injured
- 24. Soft Contact Lenses •Soft contact lenses are designed for extended wear, but can cause damage if left in for a long time • Over time, they can gradually dehydrate and shrink, making removal difficult
- 25. You can removeSoft contact lenses with the following method: – Middle finger tip on lower lid – pull lid down – Place index finger tip on lower edge of lens – slide lens down
- 26. • – Compresslens between your thumb and • index finger – allowing air to get • underneath it and remove it from the • eye • – If lens is dehydrated on the eye, run • sterile saline across the eye surface – • pinch it up to remove it
- 27. Summary • So farwe have discussed about definition, types, emergency care. Dental trauma, how to remove contact lens in eye injuries
