HEENT Flashcards
TRANSIENT
•Vision returns to normal within 24 hours, usually within 1 hour
>24 HOURS
•Sudden, painless loss
Acute Vision Loss
“ANTERIOR
•Involves the lid skin, eyelashes, and associated glands
•Eyes are ““redrimmed”” and scales or granulations can be seen clinging to the lashes
•Both present with itching, burning, mild pain, foreign body sensation, tearing. erythema of the lids, and crusting around the eyes upon awakening
Anterior Blepharitis
POSTERIOR
•Results from inflammation of the Meibomian glands
•Eyelid margins are hyperemic with telangiectasia, and the Meibomian glands and their orifices are inflamed
•Both present with itching, burning, mild pain, foreign body sensation, tearing. erythema of the lids, and crusting around the eyes upon awakening
Posterior Blepharitis
- Red eye, foreign body sensation, usually asymptomatic unless there is associated chemosis
- Blood underneath the conjunctiva, often in one sector of the eye and the entire view of the sclera may be covered by blood
- Can be caused by valsalva maneuver; coughing, sneezing, vomiting, bearing down with constipation, or other forms of straining
- Can be from trauma, hypertension and diabetes, bleeding disorder, antiplatelet or anticoagulant medication, topical steroid therapy, hemorrhage due to orbital mass, idiopathic
Conjunctival Hemorrhage
- Itching, burning, tearing, gritty or foreign body sensation; history of recent URI or contact with someone with viral conjunctivitis
- Watery discharge, red and edematous eyelids, pinpoint subconjunctival hemorrhages, punctate keratopathy
Viral Conjunctivitis
- Itching, watery discharge, and a history of ALLERGIES.
- Occurs bilaterally, chemosis, red and edematous eyelids, conjunctival papillae, periocular hyperpigmentation, no preauricular node
Allergic Conjunctivitis
- Redness, foreign body sensation, discharge; itching is much less prominent
- Purulent white-yellow discharge or mild to moderate degree
- Conjunctival papillae, chemosis, preauricular node typically absent
Bacterial Conjunctivitis
•Severe purulent discharge, hyperacute onset (within 12 to 24 hours)
•Conjunctival papillae, marked chemosis, preauricular adenopathy, eyelid swelling
- If corneal involvement, MEDEVAC
Gonococcal Conjunctivitis
•Foreign body sensation, tearing, history of trauma; with or without a rust ring
Ocular Foreign Body
•Erythema and edema of lid and conjunctivae; discharge, ocular pain or foreign body sensation, photophobia and/or blurred vision
•Visual acuity is decreased if the ulcer is located in the central visual axis
•Cornea reveals a round or irregular ulcer, with a hypopyon (white, hazy base)
•Common with contact lens wearers
* MEDEVAC*
Corneal Ulcer
- Remains painful and localized to an eyelid margin
- Tearing, photophobia, and foreign body sensation
- Small, yellowish pustule develops at the base of an eyelash
- Eyelid hyperemia, edema, swelling, and pain
Hordeolum
- Small, nontender nodule in the eyelid center
- Eyelid hyperemia, edema, swelling, and pain
Chalazion
- Trauma or recent ocular surgery are the most common risk factors
- Blood or clot or both in the anterior chamber that may be black or red
- Pain, sensitivity to light, blurred, clouded or blocked vision, history of blunt trauma
Hyphema
- ACUTE NONGRANULOMATOUS ANTERIOR UVEITIS - Pain, redness, photophobia, visual loss, hypopyon (WBC pool) and fibrin within the anterior chamber, KPs seen on the corneal endothelium
- GRANULOMATOUS ANTERIOR UVEITIS - Blurred vision in a mildly inflamed eye, ““mutton fat”” KPs and iris nodules
- POSTERIOR UVEITIS - Gradual loss of vision in a minimally inflammed eye, vitreous opacity
Uveitis/Iritis
•Red eye, pain, blurred vision, double vision, eyelid and/or periorbital swelling, nasal congestion/discharge, sinus headache/pressure/congestion, tooth pain, infra- and/or supraorbital pain, or hypesthesia
•Eyelid edema, erythema, warmth, and tenderness, Conjunctival chemosis, injection, proptosis and restricted extraocular motility with pain on attempted eye movement
•Signs of optic neuropathy may be present in severe cases
**MEDEVAC**
Orbital Cellulitis
•Pain on attempted eye movement and local tenderness, eyelid edema, crepitus (particularly after nose blowing), binocular diplopia, numbness of the cheek, upper lip, and/or teeth, acute tearing
•Restricted eye movement especially in upward or lateral gaze or both, subcutaneous or conjunctival emphysema, hypoesthesia, point tenderness, enophthalmos and hypoglobus
**MEDEVAC**
Orbital Fracture
- Caused by sunlight exposure, chronic inflammation and oxidative stress
- Wing shaped fold of fibrovascular tissue arising from the interpalpebral conjunctiva and extending onto the cornea, usually nasal in location
Pterygium
- Severe pain, tearing, and photophobia
- History of trauma to the eye, commonly involving a foreign object (fingernail, piece of paper, or contact lens)
Corneal Abrasion
