when a patient comes in with a broad complaint, what should you look at?
thyroid
how do you check for lymphadenopathy (infection of lymph system)?
push and do tiny circles with a little pressure
meibomian glands
secrete lubrication onto eyelids
palpebral
lines eyelids
clear with small vessels
bulbar
overlayes eyeball with the sclera showing thru
limbus
location where the conjunctiva merge with the cornea to cover and protect the iris and pupil
puncta
lines up with lacrimal sac, tears run down junction of puncta/lacrimal sac and down your nose
lacrimal apparatus
constant irrigation to keep conjunctiva/cornea moist
lacrimal gland in upper outer corner secretes tears
extraocular muscles
6
straight and rotary movement
eyes move as a pair because of binocular vision
movement stimulated by CN VI (abducens), CNIV (trochlear), CN III (oculomotor)
outer layer of eye
sclera and cornea
sclera
tough, protective, continuous
cornea
smooth, transparent, covers iris and allows light into the eye
CN V (sensation)
CN VII (motor)- corneal reflex
middle layer of eye
vascular choroid continuous with ciliary body and iris
lens, pupil, aqueous humor, CN III
inner layer of eye
retinal structures
optic disc, vessels, macula
HTN and DM most often target which organs?
heart, kidney, eyes
who needs an eye exam?
anyone with vision changes
greater than 40
neuro-ICP
CM, HTN
risk factors for eye problems
middle aged and older
family history of glaucoma
high intraocular pressure
african american
east asians
farsighted
had eye injury/surgery
DM
HTN
history of taking steroids
eye tests
pocket snellen
test acuity at a distance
greater denominator the worse the vision
looking for wrong answer, squinting, leaning forward
smallest line that patient can identify more than half of the letters
newborn eye exam
look at face and follow light
1 month- fixes on object
1.5 months-coordinated eye movements
3 months- eyes converge
12 months- acuity around 50/50
> 4 years- 20/40
4 and older- 20/30
refractive and correctable eye errors
myopia (nearsightedness)
astigmatism (irregular curvature of the eyes surface)

toxoplasmosis
congenital toxoplasmosis
congenital toxoplasmosis
enlargement of liver and spleen, blindness and mental retardation
external ear
auricle or pinna
helix
antihelix
tragus
antitragus
lobule
external audtiory meatus
middle ear
tympanic membrane separates external from internal
translucent
pearly gray
sound waves hitting this are what sets off the process for us to hear and vibrate
protects inner ear by reducing amplitude
allows equalization of pressures
which part of the ear is responsible for sound waves hitting this and sets off the process for us to hear and vibrate?
middle ear
malleus
incus
stapes
when can damage to the middle ear happen?
diving
inner ear
bony labyrinth
cochlea
vestibule and semicircular canals
cochlea
sensory organ for hearing
vestibule and semicircular canals
sensory organ for equilibrium
mechanism of hearing
transmits sounds-vibration-analyzed by brain
normal is air conduction
alternate is bone conduction
hearing loss
equilibrium
bone conduction for hearing
vibrations transmitted directly to CN VIII
hearing loss
sensorial
conductive
sensorial hearing loss
pathology inner ear, CN VIII or auditory area of cerebral cortex
conductive hearing loss
dysfunction of external ear/middle ear
cerumen, FB, perforated TM, otosclerosis
equilibrium of ear
labyrinth informs brain of place in space
inflammation= staggering gait
vertigo= strong spinning, whirling sensation
function of nose
warms, moistens, and filters air
external nose
nares
vestibule
columella
alar
vestibule of nose
widening of nares
columella of nose
divides nares
