HEENT Flashcards
Eye physical exam
inspect, extraoccular movement, visual fields, visual acuity, PERRLA, fundoscope
Hyperopia/Myopia/Presbyopia
hyperopia = farsighted – myopia = nearsighted Presbyopia - needs reading glasses common after age 40
Chalazion
chronic inflammatory lesion develops when meibomian tear glad becomes obstructed. Starts with eyelid swelling and erythema and then evolves into a painless, rubbery nodular lesion. Seen in pts with blepharitis or rosasea. Hordeolum leads to these. Painless. Nontender. No discharge. Can cause astigmatism from pressure.
Chalazion Treatment
Small ones resolve without treatment. Larger use a hot compress and allow them to drain. If symptomatic may need I and D or opthamology to use glucocorticoid injection. Chronic check for carcinoma.
Hordeolum
Acute purulent inflammation of the eyelid. Commonly caused by Staph Aureus. Internal: inflammed meibomian gland under the conjunctival eyelide. External: sty, on the eyelash follicle or tear gland. TENDER red bump.
Treatment Hordeolum
Both internal and external hordeola can be treated with warm compresses, placed off and on for about 15 minutes at a time approximately four times per day If the Hordeolum does not reduce in size within one to two weeks, refer to an ophthalmologist for consideration of I and C, Topical bacitracin or erythromycin optic ointment.
Periorbital cellulitis
Eyelid and facial swelling, low grade fever, recent sinusitis. Usually caused by staph/strep. Clindamycin x 10 days. Clinda covers MRSA and all 25 strep.
Orbital Cellulitis
Pain with eye movement, lid and facial swelling, orbital cellulitis affecting orbital muscles = pain w movement, can lead to orbital abscess and meningitis, encephalitis. Treat w Vanco or Rocephin
Need to be mgmt by opthamologists
acute angle closure glaucoma, iritis and infectious keratitis
Conjunctiva portion covering the globe and the lid
globe - bulbar and lid - tarsal
Bacterial Conjunctivitis
normal vision, mucopurulent discharge, discharge all day. highly contagious. caused by staph, strep, hem influenza, and moraxella. eye redness and eye discharge usually unilateral. stuck shut in the morning. yellow white and green discharge all day long. purulent discharge.
Tx Bacterial Conjunctivitis:
Erythromycin 5mg/gram ointment 4 x a day x 1 week or Azithromycin 1% 1 drop BID x 2 days then 1 drop daily 5 days
Hyperacute Bacterial Conjunctivitis
Neisseria species, particularly N. gonorrhoeae, can cause a hyperacute bacterial conjunctivitis. The organism is usually transmitted from the genitalia to the hands and then to the eyes, usually presents w urethritis, chemosis, lid swelling and tender preauricular lymphadenopathy. Starts within 12 hours of inoculation. Tx Ceftriaxone IM can lead to blindness need to be hospitalized
Viral Conjunctivitis
Typically caused by adenovirus. May be part of a viral prodrome. normal vision, mucoserous discharge, “gritty” “burning” “sandy” , preauricular lymph node, tarsal conjunctiva may be bumpy, hx URI. second eye involved 24-48 hours.
Viral Conjunctivitis tx
Cool compress, decongestant, handwashing
Epidemic keratoconjunctivitis(EKC)
A form of viral conjunctivitis; the corneal and conjunctival epithelium are both involved.
Caused by adenovirus 8, 19, 37. same s.s as viral, may also feel multiple FB sensations caused by corneal infiltrates. may threaten vision, refer to opthalmology
Allergic Conjunctivitis
Caused by airborne allergens contacting the eye that release of chemical mediators including histamine, eosinophil chemotactic factors, and platelet-activating factor
presents as bilateral redness, watery discharge, and itching Itching is the cardinal symptom of allergy, distinguishing it from a viral etiology. Normal vision. Watery discharge. Prominent chemosis. Diffuse injection, watery discharge, may have morning crusting May have extreme bullous chemosis if hypersensitive to cats
Treat for Allergic Conjunctivitis
Naphcon-A occurlar decongestant or mast cell stabilizer Patonol
Nonallergic Noninfectious Conjunctivitis
Bilateral red eye and discharge that is mucus. Cause is transient mechanical or chemical insult
Red eye with change of vision can be these:
Iritis, acute closed angle glaucoma, Keratitis
Keratitis s/s
pupil very small, 1-2mm and very photophobic
Closed angle glaucoma s/s
pupil is midsize 4-5mm and fixed does not react to light, also has corneal edema and high intraoccular pressure
very small pupils 1-2mm
corneal abrasion, infectious keratitis, iritis
test for corneal abrasions
flouroscein examination
purulent discharge found in
bacterial conjunctivitis and bacterial keratitis
emergent referral red eye
angle closure glaucoma, hyphema, hypopyon, bacterial keratitis. urgent- iritis, viral keratitis
Blephoritis and treatment
pink eyelid edges, crusting, Chronic inflammation. Treatment: clean with diluted baby shampoo
Pseudomonas and treatment
pink eye with no or minimal discharge, no change in vision, wears contacts. need a fluroquinolone – cipro or moxi
Corneal abrasion and treatment
normal or decrease acuity, photophobia, FB sensation, watery discharge need fluroscein stain. if >2mm need opthamology. give abx to prevent corneal ulceration. Treatment: topical abx.hx of Trauma or contacts. will see epithelial defect on exam. Treat need pain control, topic abx no eye patch no topic pain relievers.
Corneal ulcer
pain, sensitivity to light, acuity normal or decreased, purulent discharge, FB sensation, white infiltrate. cornal opacification. refer 12-24 hours need culture and topic fq antibiotics. can lead to corneal scaring and perforation
At risk for glaucoma
increased IOP, myopia, DM, blacks, elderly, hypothyroid, family hx, htn
Patho of open angle glaucoma
In open-angle glaucoma, optic nerve damage results in a progressive loss of retinal ganglion cell axons, which is manifested initially as visual field loss and, ultimately, irreversible blindness if left untreated. related to increased aqueous production and decreased outflow
The optic nerve or “disc” takes on a hollowed-out appearance on ophthalmoscopic examination, which is described as “cupping.”
s/s open angle Glaucoma
peripheral field loss then central loss, slow onset, IOP > 22,
angle closure glaucoma patho
When this drainage pathway is narrowed or closed, inadequate drainage leads to elevated intraocular pressure and damage to the optic nerve . Acute angle-closure glaucoma occurs in eyes with a certain anatomical predisposition. It presents as a painful red eye and must be treated within 24 hours to prevent permanent blindness
s/s closed angle glaucoma
severe unilateral eye pain, blurred vision, halos, photophobia, nausea, conjunctival erythema, and corneal edema.
Glaucoma screening
A typical frequency for repeat evaluation for individuals between ages 40 and 60 is every three to five years for those without risk factors
every one to two years for those with one or more risk factors The AAO also suggests periodic examination for black men and women between ages 20 to 39.
Optic disc cupping
A cup whose diameter is greater than 50 percent of the vertical disc diameter is indicative of glaucoma
Cataract
Opacity of the lens, age related after age 70 some sort of cataract is expected, s/s frequent glasses prescription changes, film over the eye, halos pt c/o problem driving at night or reading signs, fine print. increased nearsightedness.
Risk factors for cataracts
age, smoking, alcohol, low education, malnutrition, inactivity, sunlight, metabolic syndrome, diabetes, systemic corticosteroid use, statin use
immature cataract
can view the retina and transmits the red reflex
mature cataract
no longer transmits red reflex
hypermature cataract
brown nucleus, white liquified cortex,
diagnosis of cataract
painless decline in vision, fundoscopic exam to see lens opacity, may have darkened red reflex or opacities in red reflex – need opthamologic exam non urgent
patho retina detachment
Retinal detachment occurs when the multilayer neurosensory retina separates from the underlying retinal pigment epithelium and choroid, can be caused by leak in the retina or a break
vitreous traction
a condition in which the vitreous gel has an abnormally strong adhesion to the retina.
The gel tends to pull forward and can cause vessel and retinal distortion causing retinal swelling and decreased vision
s/s retinal detachment
floaters like cobwebs or houseflies, caused by the vitreous gel separating from the retina, at night may see flashes of light – need urgent evaluation
Iritis/Uveitis
Reduced visual acuity,(+) photophobia, pain, no discharge , MIOTIC or irregular pupil, PERILIMBAR flush
Impacted cerumen s/s
Dizziness, hearing loss, tinnitus, discomfort and otitis externa
Treatment for Impacted Cerumen
3% hydrogen peroxide or mineral oil/almond oill/olive oils or debrox which is non water and non oil. Can manually use a curette, forceps or spoon
impact on hearing loss on the elderly
social isolation, personal safety, communication
Neurosensory loss
From hairs in ear not converting sound, from age presbycusis
Conductive loss
mechanical from wax, ear drum, bones, fluid in middle ear
If abrupt or acute hearing loss
refer immediately
Subjective questions to ask for hearing loss
head injury, noise exposure, ototoxic medications like aspirin, aminoglycosides, furosemide, quinine drugs. S/s of vertigo, pain, fullness, tinnitus, cranial neuropathies
Objective Exam hearing loss
head and neck, test cranial nerves, use pneumatic otoscope for TM mobility, auditory tests like weber (normal heard equal both ears) it will lateralize to the bad year if conductive loss, and lateralize to the good ear if sensorineual loss. Rinne normally AC
Diagnostics hearing loss
Audiometry - pure tone, speech and impedance. MRI or CT. Labs: CBC r/o anemia, infection. VDRL or RPR r/o syphillis. Rheumatoid factors. TSH for hypo or hyperthyroid
MGMT hearing loss
Refer to ENT or audiology. Treat any infections. Hearing aid if conductive loss. Surgery for: 1 tumors, 2 TM perforation patch, 3 otosclerosis (progressive disease affecting the bone surrounding the inner ear and footplate of stapes)
Presbycusis
age related hearing loss, degeneration within the cochlea, sensorineual, usually both ears, treatment: better communication, hearing aids but 3000 each, cochlear implants
Vertigo
room spinning. DD: presyncope, dizziness, benign parozymal positional vertigo, labyrinthritis, meniere’s disease. Most are benign positional.
