Midterm Flashcards
this is considered positive if there is ANY inequality of color - what is it?
Red Reflex
- MUST be performed on all children to assess the eye.
This is considered an ophthalamic emergency as it leads to vision loss - what is it?
congenital cloudy cornea
- req. surgery by 3-4mos
causes:
- glaucoma
- trauma
- scleroderma
- rhabdomyosarcoma
when the visual axis of the eyes are non-parallel - what is this called?
strabismus
when does coordinated movement of the eye develop?
by 3-6mo
when infants begin using binocular vision
- if deviated 6+ mo; refer for eval
there are two types of strabismus - what are they?
exotropia - eyes are divergent
esotropia - eyes are crossed
there are two potential causes of strabismus - what are they?
supranuclear - visual cortex
infranuclear - extraocular muscles or their nerves
this is a term for loss of vision
amblyopia
approximately 50% of children with strabismus under 9 years of age will develop this if the eye is left untreated - what is it?
amblyopia - loss of vision
- current treatment is patching preferred eye.
- chronic strabismus can be disfiguring
this is a stricture of the nasolacrimal duct, often resulting from a congenital abnormality - it presents between which ages as a persisting tearing of one or both eyes?
Dacrostenosis
- presents b/w 3-12 wks of age
- usually UL
generally resolves spontaneously by 6mo age
this is an infection of the lacrimal sac, usually secondary to dacrostenosis. It presents as pain, erythema and edema about the lacrimal sac. There is often tearing and conjunctivitis - what is this?
dacrocystitis
- managed with warm compresses, eye wash or topical antibiotics
- parents can milk contents of lacrimal sac through the nasolacrimal ducts with fingertip massage (BID)
for conjunctivitis - there are three etiologies - differentiate them according to the discharge
bacteria - mucopurulent d/c with eyelid swelling (usually staph)
viral - watery, clear d/c, minimal eyelid swelling (gen. follows URI)
allergic - clear, mucoid, ropy d/c, moderate to severe lid edema, itchy
for conjunctivitis - there are three etiologies - differentiate them according to how many eyes are gen. involved
bacterial - UL, may spread to BL
viral - BL
allergic - BL
this type of cellulitis presents with edema and swelling of the upper and lower eyelid, presenting with fever and pain - it’s generally UL or BL? - what is it?
periorbital cellulitis (UL)
it involves the eyelid AND surrounding skin
Tx with antibiotics, gen IV
this type of cellulitis presents with a swollen eyeball that bulges and decreased movement of the eye with decreased vision - what is this?
orbital cellulitis
involves the periorbital and orbital contents
REQUIRES IMMEDIATE REFERRAL for IV ANTIBIOTICS
- augmentin generally
what two things can cause periorbital or orbital cellulitis? What are potential sequelae we need to be aware of?
etiology
- trauma/bug bite (gen staph aureus or strep pyogenes)
- internal infxn: sinusitis/bacteremia (gen. h. influenza type b or strep pneumonia)
sequelae
- retinal damage d/t ischemia
- meningitis, brain abscess
this is an inflammation of the lid margins with erythema, thickening and crusts, scales or shallow marginal ulcers - loss of eyelashes may be present - what is this?
blepharitis
- herbal eyewash, antibiotics, homeopathy
- prevent recurrence
this is an acute, localized pyogenic infection of one or more of the Zeis or Moll or Meibomian glands - generally caused by staph - it presents with pain, redness and tenderness - may find small areas of induration or an internal or external “head” - what is it?
Hordeolum (stye)
tx with hot packs for 10 mins TID; homeopathy
RARE to tx with antibiotics
if one parent has allergies vs if both do - what are the chances of the child developing allergies?
one parent - 30% chance
both parents - 70% chance
when supine - rhinitis causes which two symptoms?
post-nasal drip
cough
- can be assoc w/ eustachian tube obstruction
rhinitis is, in general - associated with what?
URI
- d/c can be clear to white to yellow to green
- thin or thick
can be chronic during WINTER months
an infant presents to your office sticking its tongue out, maybe displaying a shallow cough and is avoiding swallowing - what may this be?
sore throat
gen. viral etiology
usually associated with URI sx
- coryza
- conjunctivitis
- malaise
- hoarseness
if a child presents with sore throat and a LOW-GRADE fever, what does this suggest?
viral pharyngitis
may also present with:
- mouth-breathing
- vomiting
- abd. pn
- diarrhea
this virus generally presents with red papules, vesicles and ulcers on the tongue, buccal mucosa, palate, gingival and uvulo-tonsillar pillars.
Often you’ll see 2-10 lesions that persist x1wk. Additional papule or vesicular exanthema on hands and or feet (sometimes also on the arms, legs, BUTTOCKS and face) with mild constitutional sx - what is this?
Coxsackie virus
- Hand, Foot and Mouth
you see small, red papules, vesicles and ulcers ont he posterior oropharynx - with a high fever - what do you suspect this to be?
herpangina
