Q

strabismus

A

type of amblyopia
ocular misalignment–foveal misalignment
2 different images that can’t be fused into one
leads to suppression of one eye by the visual cortex
suppression–deviation relatives to the fixated eye (fixated eye= the eye getting the clear image)

Q

cover/uncover test

A

detects latent strabismus. **if the cover test is positive, the cover/uncover test doesn’t necessarily need to be done. if the cover/uncover test is negative, then you want to the cover/uncover test

child will focus on a target, a cover is placed over one eye for a few seconds. then it is rapidly removed. the eye that was covered is observed and noted for the refutation movement back to center and latent strabismus is identified.

Q

cover test

A

child should be focused on a target, you want to cover one eye while observing the opposite eye for movement. if no movement detected, that is considered normal. if strabismus or tropia, the eye that is not occluded with the cover test shifts to refixate on the target. the test should be repeated on each eye. a positive cover test–> should be referred.

Q

Bruckner test (simultaneous red reflex test)

A

checks the red reflex and makes sure it is symmetrical and the pupils are checked for color, symmetry, size, shape, and brightness.
Asymmetry–> referral to pediatric ophthalmologist immediately as this could indicate a series ocular disorder, caner for strabismus, opacities, and retinal tumors

Q

tx for strabismus

A

early recognition for prompt referral to opthamlmolgy
tx may include:
-corrective lenses
-prism lenses
-botox
-vision therapy
-occlusion therapy
-pharm penalization
-surgery
observation and regular follow-up

20
Q

16 weeks

A

anterior eye fully developed

21
Q

7 months

A

fetus can open eyes

22
Q

10-12 yrs

A

volume of orbit complete

23
Q

prematurity (early gestational age and low gestational weight)

A

increases the risk of retinopathy of prematurity–> warrants immediate referral to ophthalmology

24
Q

25 weeks-5-6 months

A

most critical time of neurosensory development in the auditory system

25
hearing screening: first
otoacoustic emission (OAE)
26
hearing screening: second
auditory brainstem response (ABR)
27
hearing screening
+OAE---> ABR +ABR--> ABR
28
sensorineural hearing loss: causes
disorders of the inner ear
28
sensorineural hearing loss: types
congenital: infection, hereditary acquired: loud, repetitieve noises, tumors, infection, prematurity, ototoxic drugs, trauma
28
tx of conductive hearing loss
removal of cerumen/foreign body resolution of fluid (treating the middle ear effusion) hearing aids
28
conductive hearing loss: causes
cerumen impaction middle ear effusion cholesteatoma impaired ossicles
28
middle ear effusion
caused by fluid buildup in the space behind the eardrum associated w/ mild conductive hearing loss that normalizes once the effusion resolves
28
tx of sensorineural hearing loss
hearing aids cochlear implants
28
middle ear effusion: s/s
symptoms can last up to 12 weeks but should resolve on own if hearing loss is severe or persistent refer to ENT
29
cholesteatoma
squamous epithelium accumulation congenital or acquired secondary to chronic otitis media
30
cholesteatoma physical exam findings
whitish pearl on TM, may appear like tympanosclerosis (whitish scarring on TM) but less fuzzy border
31
management of cholesteatoma
REFER TO ENT ASAP -surgical removal--> structural changes to external auditory canal requiring lifelong ENT f/u
32
labs/diagnostics of cholesteatoma
puretone audiogram CBC w/ diff to r/o anemia or infection ESR, ANA, RF to r/o autoimmune disease otoacoustic emissions, tympanometry (OAE) TSH CT scan or MRI if tumor is suspected
33
hearing loss
intervention services by 3 months, no later than 6 months
34
prevention & management
AVOID use of ototoxic drugs (aminoglycosides, diuretics) reduce repeated exposure to loud noises to avoid acoustic trauma any pt with sudden onset SNHL should be seen by otolaryngologist immediate (may initiate steroid tx to reverse loss but must be done quickly) conductive hearing loss TYPICALLY correctable SNHL is NOT reversible but manageable with cochlear implants when possible
35
when should you refer
child fails a hearing screening--> audiology has a suspected hearing loss--> audiology any child with hearing loss--> otolaryngologist infants that fall into SNHL high risk category and/or h/o developmental delay, bacterial meningitis, ototoxic medication exposure, neurodegenerative disorders, mumps or measles bacterial meningitis--> otolaryngologist bc of concern of cochlear ossification even if newborn screening passed but at increased risk for progressive or delayed onset hearing loss--> ongoing audio logic monitoring for 3 years and @ appropriate intervals thereafter
36
recurrent strep
most likely to occur in settings with close contact facilitating transmissions--> households, schools, daycares evaluation: repeat testing for GAS
37
what toes a repeat + test mean
non adherence recurrent infection persistent infection new and chronic GAS carriage complication
38
chronic group A strep pharyngitis
most likely not going to treat bc less likely to transmit and less likely to develop suppurative complications or acute RF
39
who to treat?
local outbreak of acute RF and poststreptococcal glomerulonephritis outbreak of GAS pharyngitis in closed/semi-closed communities, households, or other close contact settings Family hx of acute RF consideration for tonsillectomy solely due to frequent GAS isolations
40
tx for chronic group A strep pharyngitis
1st line: clindamycin **increased risk for C diff
41
tonsillectomy and/or andenoidectomy in children
depends on severity and frequency of reinfection severe: 7+ episodes in one year, 5+ episodes in each of 2 years, 3+ episodes in each of 3 years mild and moderate: not recommended, benefits don't outweigh the risk
42
GAS complications to consider
h/o peritonsillar abscess h/o rheumatic heart disease or close contact with a person w/ rheumatic heart disease
