Module 2 - HEENT Flashcards
Occurs naturally in older adults; prevalence increases with age
Associated w/ decreased QOL, functional ability, increase in safety issues (falls, MVA), some cognitive impairment r/t decreased vision
Progressive and irreversible → surgical removal safe and effective
-> Increasing age, DM, smoking, fam hx, long term corticosteroid use, HTN, trauma, UV light exposure without protection
Cataracts
Opacity of lens
Patient ℅ glare or halo around lights (esp at night), difficulty night driving, polyopia (multiple images), difficulty reading newspaper
Cataracts
PE for cataracts
What to expect?
Visual exam (decreased visual acuity), normal pupillary response, haziness during fundoscopic exam Evaluate red reflex 1 ft away from patient→ if yellowish/whitish tint present inside pupil, refer
Tx for cataracts
Watchful waiting if early
Slow progression by: decreasing sun exposure (sunglasses, hats), smoking cessation
Refer if
-> Main cause of vision loss; functioning and ability to perform ADLs affected; pt understands surgery is needed and is agreeable
Main tx: surgical correction
Leading cause of blindness worldwide
Pressure buildup in eye where too much pressure on optic nerve r/t fluid buildup → causes irreversible damage to optic nerve and permanently changes sight
Glaucoma
“silent stealer of sight” (MOST COMMON)
Triad—> tearing, photophobia, excessive blinking (blepharospasm)
Open angle glaucoma
Vision damage irreversible; significant progression by time central vision affected
> 50 y/o, fam hx, African Americans, thin central cornea, myopia, DM2, corticosteroid use (long term)
Most do not complain of sx; some may ℅ peripheral vision loss
Triad—> tearing, photophobia, excessive blinking (blepharospasm)
Open angle glaucoma
PE for open-angle glaucoma
diagnostics?
Fundoscopic exam → optic disk cupping
Tonometer (measures intraocular pressure) → ophthalmology
Tx for open-angle glaucoma?
goals?
Topicals (drops to lower eye pressure: beta adrenergic antagonists, cholinergic eye drops) → expensive!
Book: BB- Timolol
Carbonic anhydride- Dorzolamide/ Brinzolamide
Surgery for severe cases
Goal= Decrease IOP & stop damage
education for open-angle glaucoma?
All members needs to get IOP checked
Med compliance
No excessive physical/ emotional stress, no straining
F/U is for LIFE- q3-6mo
True angular abnormality
Usually found when pt ℅ unilateral HA, visual blurring/cloudiness, rings around lights, n/v, photophobia
- Females, older age, asian descent
Ophthalmologic emergency → REFER
closed angle glaucoma
May see hazy cornea, nonreactive pupils that are semi dilated, scleral injection
tx= surgery
Ophthalmologic emergency → REFER
closed-angle glaucoma
Leading cause of blindness in those over 50 y.o in the US
Macular degeneration/ ARMD (age-related MD)
Two types of Macular degeneration/ ARMD
Dry (better prognosis) and wet
Early, intermediate and advanced sx of Macular degeneration/ ARMD
Early (dry): Asx
Intermediate (dry): vision changes, blurred in one or both eyes, difficulty with fine motor(reading, driving)
Advanced (wet/bad prognosis): Acute onset, metamorphosis (wavy—> straight lines)
PE for Macular degeneration/ ARMD
diagnostics?
Fundoscopic exam- dilation needed
Visual acuity. Confrontation
External/lids
Dx= Amsler grid (test each eye)
Tx for Macular degeneration/ ARMD diagnostics?
There is no cure
STOP smoking
Dry (better prognosis): High dose antioxidant vitamins/ Beta carotene + zinc: reduce risk and slow progression
Wet MD: intravitreal vascular endothelial growth factor (VEGF) injections: slow down progression + improve vision
Laser surgery
Localized bacterial infection of the skin and subq tissues anterior to the orbital septum (outside of bony orbit)
AKA: affects soft tissues in front of orbital septum
Typically seen in children
More common in winter r/t increase in sinus infections
(Hib, staph aureus, MRSA, strep)
Periorbital (preseptal) cellulitis
Swelling around eyelid and eye (periorbital), erythema and warmth in area, painful (but not painful to move eye), conjunctivitis may be present or the cause, blurred vision possible BUT pupillary response should be normal
Periorbital (preseptal) cellulitis
Tx for Periorbital (preseptal) cellulitis
Try to identify source of infection
If mild (no fever, mild erythema, patient stable) outpt with abx -> Amox-clav (augmentin) OR 3rd gen cephalosporin
If MRSA suspected
Double strength trimeth-sulfa (bactrim), clindamycin, or doxy (no doxy <9 y/o)
Requires CLOSE followup, check back in 24 hours, if no improvement or worsens → refer for IV abx
If questioning preseptal vs orbital → refer for CT
More serious than periorbital; must differentiate btw the two; refer if you can’t!
Infection located posterior to orbital septum
Frequently preceded by a sinus infection (ethmoid sinuses)
Can have serious complications (blindness, death)
Can put pressure on optic nerve if the infection spreads which can lead to brain abscess and sepsis
(roup A beta-hem strep, s aureus, s pneumoniae, Hib, other strep, anaerobic microorganisms)
Orbital cellulitis
