Topics • Eyelids • Red Eye • Trauma

Anatomy of the Eye

Ectropion • • • •

Congenital Senile Paralytic Cicatricial

Blepharitis

Blepharitis • Refers to any inflammation of the eyelid • In general refers to a “mixed” blepharitis – With flakes and oily secretions on lid edges – Caused by a combination of factors • Hypersensitivity to staphylococcal infection of the lids • Glandular hypersecretion

• Treat with warm, moist towel compresses and dilute baby shampoo scrub

Chalazion

Chalazion • Focal, chronic granulomatous inflammation of the eyelid caused by obstruction of a Meibomian gland • Treat by excision using chalazion clamp • May recur

Hordeolum

Hordeolum

Hordeolum • Painful, acute, staphylococcal infection of the Meibomian or Zeis glands • Has central core of pus • External and internal • Treat with antibiotic ointment and dry heat

What is this?

Xanthelasma

Xanthelasma • Lipoprotein deposits in the eyelids • Often an indicator of underlying lipid disorder • Cosmetic significance • May be removed, but recur

What is the name of this?

Dacryocystitis • Inflammation of the lacrimal sac • Usually caused by obstruction of nasolacrimal duct with subsequent infection • Unilateral • Treat with pus drainage (stab incision), local and systemic antibiotics • Definitive treatment: fistula of lacrimal sac and nasal cavity (dacryocystorhinostomy)

Dacryoadenitis

Dacryoadenitis

Dacryoadenitis • Acute painful swelling, ptosis of lid, edema of the conjunctiva due to lacrimal gland inflammation • Often infectious: pneumococci, staphylococci, occasionally streptococci • Chronic form: longer DDx • Treat acutely with moist heat and local antibiotics.

Red Eye

Conjunctivitis • Inflammation of the eye surface • Vascular dilation, cellular infiltration, and exudation • Acute vs. Chronic

Conjunctivitis • Infectious – Bacterial – Viral – Parasitic – Mycotic

• Noninfectious – Persistent irritation (dry eye, refractive error) – Allergic – Toxic (irritants: smoke, dust) – Secondary (Stevens-Johnson)

Historical Clues • • • • •

Itching Unilateral vs. Bilateral Pain, photophobia, blurred vision Recent URI Prescription, OTC medications, contact lenses • Discharge

Bacterial Conjunctivitis

What’s wrong with this picture?

Bacterial Conjunctivitis

Conjunctivitis, American Family Physician, 2/15/1998; http://aafp.org/afp/980215ap/morrow.html

Bacterial Conjunctivitis • Dx based on clinical picture – History of burning, irritation, tearing – Usually unilateral – Hyperemia – Purulent discharge – Mild eyelid edema – Eyelids sticking on awakening – Cultures unnecessary unless very rapid progression

Bacterial Conjunctivitis • Treatment: – Treatment decreases morbidity and duration – Treatment decreases risk of local or distal consequences – Topical antibiotic ointment / solution

Bacterial Conjunctivitis • Erythromycin • Bacitracin-polymyxin B ointment (Polysporin) • Aminoglycosides: gentamicin (Garamycin), tobramycin (Tobrex) and neomycin • Tetracycline and chloramphenicol (Chloromycetin) • Fluroquinolones

Viral Conjunctivitis • • • •

AKA epidemic keratoconjunctivitis AKA “pinkeye” Most frequent VERY contagious – direct contact – Wash hands, expect contamination of other eye and family members

• Adenovirus 18 or 19 • Acute red eye, watery, mucoid discharge, lacrimation, tender preauricular Lymph Node • Occasional itching, photophobia, foreign-body sensation • History of antecedent URI

Herpes Keratitis • • • • •

Herpes simplex Herpes zoster Corneal Dendrite Do not use steroid drops! Aggressive treatment with antivirals, may need debridement • Refer to ophthalmologist

Herpes Keratitis

Herpes Keratitis

Allergic Conjunctivitis

Vernal Conjunctivitis

Allergic Conjunctivitis • Seasonal, itching, associated nasal symptoms. • Treat with cool compresses. systemic antihistamines, local antihistamines or mast cell stabilizers, local NSAIDs.

Surface Diseases • Nevi • Melanoma • Pterygium

Benign – Pigmented Nevus

Pigmented nevus • Flat, cysts, may grow during hormonal changes (pregnancy, puberty), can be elevated, • Variably pigmented, stationary

Tumors - Melanoma

melanoma • PAM, pre-existing nevus, De novo • Variably pigmented mass, prominent conjunctival vessels, can involve: cornea, fornices, and can invade the orbit and globe • Treatment: Surgical

Benign - Pterygium

Pterygium • Fibrovascular growth that extends from the conjunctiva into the cornea • Usually from Sun, UV trauma, and wind exposure. More common in equatorial regions and people that work outside • Treatment: surgical

Basal Cell CA

Basal Cell CA • 90% of eyelid malignancies • Classified as malignant because of its local invasiveness • Almost never develops distant metz • Lower lid 55%, medial canthus 30%, upper lid 10%, lateral canthus 5% • Elevated mass, thickened well defined erythematous margins, central crater or ulcer

Tumors - SCC

Squamous Cell CA • • • • •

<5% of malignant eyelid tumors Often arises from actinic keratosis Elevated keratinizing mass Similar to basal cell carcinoma Can metastasize to regional lymph nodes

Trauma • Trauma accounts for 5% of the blind registrations annually • 65% under 30 year old age group • Males to females 6:1 • 95% caused by carelessness • Routine eye protection

Lions Eye Institute Ophthalmology Tutorials; http://www.lei.org.au/~leiiweb/teaching/undergrad/Ocular_trauma/ocular_trauma0.htm

Trauma • • • • • • •

Motor vehicle accidents Sport - 22% of ocular trauma hospital admissions Industrial - 44% of ocular trauma hospital admissions Assault Domestic injuries and child abuse Self inflicted - Often mentally disturbed people War

Trauma • Superficial including chemical • Blunt (contusion) injury • Perforating may include intraocular foreign body

Trauma – First Aid • • • • • •

Hold open eyelids Irrigate with water Carefully remove coarse particles Topical anesthesia – not for taking home! Evert eyelids and inspect under slit lamp Give systemic pain meds if needed

Trauma - Pearls • Take history, document pre-injury status • Always consider the possibility of ocular penetration or the presence of a foreign body • If penetrating trauma is suspected avoid direct pressure on the globe • If an intraocular foreign body is suspected radiologic studies may be necessary

Trauma – Blunt • Always consider the possibility of injury to the globe, the eyelids and the orbit • Damage can occur from: – The site of impact (coup injury) – Shock wave traversing the eye and causing damage on the other side (contra coup)

Trauma – Blunt • Check – ocular motility – intraocular pressure – vision

Trauma - Foreign Body

Trauma – Foreign Body

Foreign Body – Iris Prolapse

Foreign Body • Evert upper lid • Must be extracted – Rust rings in cornea – Retinal damage from free radicals

Trauma - Hyphema

Trauma - Hyphema

Trauma – Hyphema • • • •

Set patient upright to allow settling Will resolve by itself May cause corneal staining Check for increased intraocular pressure
