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

IntroductionIntroduction

• 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.

Anatomy and Physiology of the EyeAnatomy 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


• Oculomotor nerve (third cranial nerve)− Cause motion of the eyeballs and upper eyelids

• Optic nerve (second cranial nerve)− Provides the sense of vision


• Eye structures − Sclera (“white of

the eye”)

− Cornea

− Conjunctiva

− Iris

− Pupil

− Lens

− Retina• Converts light

impulses to nerve signals


• Anterior chamber: between lens and cornea− Filled with aqueous humor

• Posterior chamber: between iris and lens − Filled with vitreous humor


• 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.


• 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


• Lacrimal apparatus− Secretes and

drains tears from the eye

− Tears moisten the conjunctivae.

Patient AssessmentPatient Assessment

• Ensure scene safety.

• Keep your patient calm.

• Form a general impression.

• Assess airway and breathing.

• Cover both eyes.

• Consider pain management.

• 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


• Obtain a full set of baseline vital signs.

• The patient may experience side effects if:− Used more than one eye medication

• Ask how he or she administered the medication.


• 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.


• Irrigation may be necessary.− Use sterile water or isotonic saline solution.
