National EMS Education Standard Competencies Diseases of the Eyes, Ears, Nose, and Throat Knowledge of the anatomy, physiology, epidemiology, pathophysiology, psychosocial impact, presentations, prognosis, and management of Common or major diseases of the eyes, ears, nose, and throat, including nose bleed
Slide 4-

Introduction Calls may involve disorders of the eyes, ears, nose, and throat (EENT). Patients may need to be transported to an emergency department with access to a specialist.
Slide 5-

Anatomy and Physiology of the Eye The globe measures about 1 inch in diameter. Housed within the orbit Held in place by connective tissue and muscles Control eye movement
Slide 6-

Anatomy and Physiology of the Eye Oculomotor nerve (third cranial nerve) Cause motion of the eyeballs and upper eyelids Optic nerve (second cranial nerve) Provides the sense of vision
Slide 7-

Anatomy and Physiology of the Eye
Slide 8-

Anatomy and Physiology of the Eye Eye structures Sclera (“white of the eye”) Cornea Conjunctiva Iris Pupil Lens Retina Converts light impulses to nerve signals
Slide 9-

Anatomy and Physiology of the Eye Anterior chamber: between lens and cornea Filled with aqueous humor Posterior chamber: between iris and lens Filled with vitreous humor
Slide 10-

Anatomy and Physiology of the Eye Light rays enter the eyes through the pupil. Focused by the lens Image is cast on the retina The optic nerve transmits the image to the brain. The visual cortex coverts it into a conscious image.
Slide 11-

Anatomy and Physiology of the Eye Two types of vision Central vision Enables visualization of objects directly in front of you Peripheral vision Enables visualization of lateral objects while a person is looking forward
Slide 12-

Anatomy and Physiology of the Eye Lacrimal apparatus Secretes and drains tears from the eye Tears moisten the conjunctivae.
Slide 13-

Patient Assessment Ensure scene safety. Keep your patient calm. Form a general impression. Assess airway and breathing. Cover both eyes. Consider pain management. Cardiac monitoring is recommended.
Slide 14-

Patient Assessment Obtain chief complaint and history. OPQRST Diabetes is the leading cause of new cases of blindness in adults. Diabetic retinopathy
Slide 15-

Patient Assessment Symptoms that may indicate a serious ocular condition: Visual loss that does not improve with blinking Double vision Severe eye pain Foreign body sensation Perform a thorough examination.
Slide 16-

Patient Assessment Assess for: Pain/tenderness Swelling Abnormal or loss of movement Sensation changes Circulatory changes Deformity Visual changes Airway compromise
Slide 17-

Patient Assessment Assess structures: Orbital rim Ecchymosis, swelling, lacerations, and tenderness Eyelids Ecchymosis, swelling, lacerations, or any abnormalities Corneas Foreign bodies
Slide 18-

Patient Assessment Assess structures: Conjunctivae Redness, pus, inflammation, and foreign bodies Globes Redness, pigmentation, and lacerations Pupils Size, shape, equality, and reaction to light
Slide 19-

Patient Assessment When assessing ocular function, test: Visual acuity Ability to see large and small letters Peripheral vision Ability to recognize an object entering the visual field Ocular motility Ability to move the eyes in all directions
Slide 20-

Patient Assessment Obtain a full set of baseline vital signs. The patient may experience side effects if: Used more than one eye medication Used too much medication Ask how he or she administered the medication.
Slide 21-

Patient Assessment Eye drops and lubricants can be applied by: Gently squeezing the lower eyelid Applying the medication Have the patient close the eyes and roll them. Apply gentle pressure to the corner of the eyes to prevent drainage.
Slide 22-

Patient Assessment Irrigation may be necessary. Use sterile water or isotonic saline solution. Flush from the inside corner to the outside. Eye injuries should be seen in the emergency department.
Slide 23-

Burns of the Eye and Adnexa Can be caused by: Chemicals Heat Light rays Thermal burns Occur when a patient is burned in the face during a fire
Slide 24-

Burns of the Eye and Adnexa Retinal injuries caused by extremely bright light: Generally not painful May result in permanent damage Superficial burns of the eye: May not be painful initially Symptoms include: Conjunctivitis Redness Swelling Excessive tear production
Slide 25-

Burns of the Eye and Adnexa Assessment and management Assess for and treat life-threats. May be difficult if eyes are closed Open the eye and irrigate with sterile water or sterile saline solution. Pain may have to be managed before assessment.
Slide 26-

Burns of the Eye and Adnexa Assessment and management (cont’d) Assess positions of gaze. Cover an eye burned by ultraviolet light with: Sterile, moist pad Eye shield Transport in a supine position.
Slide 27-

Burns of the Eye and Adnexa Assessment and management (cont’d) Chemical burns require immediate irrigation. Direct as much fluid as possible. Use a device that will control the flow. Do not allow contaminated fluid to enter the eye. Irrigate for at least five minutes.
Slide 28-

Burns of the Eye and Adnexa
Slide 29-

Burns of the Eye and Adnexa
Slide 30-

Burns of the Eye and Adnexa Assessment and management (cont’d) Use of the Morgan lens (eye irrigation device) Administer a topical anesthetic. Connect the lens to the IV bag, and let it drip. Slide the Morgan lens under the eyelids. Run the fluid at the desired rate.

Foreign Body Can cause significant pain Commonly caused by machines such as: Grinders Sanders Nailers Weed whackers
Slide 39-

Foreign Body Assessment and management Evaluate the entire eye using a light. Examine the undersurface of the upper eyelid. If you spot a foreign object on the surface, attempt to remove it with a moist, cotton-tipped applicator.
Slide 40-

Foreign Body Assessment and management (cont’d) To assist with dislodging: Irrigate the eye with a sterile saline solution. Transport the patient to the hospital.
Slide 41-

Foreign Body Assessment and management (cont’d) Do not remove an impaled foreign body. Stabilize in place. Cover with a moist, sterile dressing. Place a protective barrier over the object. Cover unaffected eye. Transport promptly.
