vector borne disease transmitted lyme and rocky mountain spotted fever
through ticks
dark adaptation curves - the flashing stimuli is typically 420 nm
- initial portion of the curve displays a rapid decrease
in threshold during the first five minutes, which
correlates with the regeneration of cone pigments
and cone thresholds
- second portion is the rod-cone break where rods
are more sensitive than cones
- cones recover in 10 mins and rods 35 min
- if the stimulus changes to a longer wavelength, then
the curve will lack a rod-cone break
collaterals are most commonly retinal vein occlusion
observed in associated conditions
positiv forced duction test eye will resist mechanical duction
pseudomonas aeruginosa gram negative - most common cause of corneal
ulcers in pt who wear cl
- treated with fluoroquinolones
,class 1 agents affect sodium channels to prevent ventricular
arrhythmias
ex. lidocaine
class 2 agents decrease sympathetic activity in heart by blocking
beta adrenergic receptors and aid in preventing
recurrence of mi
ex. propranolo
class 3 agents prolong repolarization by blocking potassium
channels and prevent arrhythmias
ex. amiodarone
class 4 agents block calcium channels, thereby decreasing
conduction through av node
ex. verapamil and diltiazem
excitation and emission of fluorescein - excitation peak is 490/blue range
- emission peak is 530/green range
average upper eyelid excursion 15 mm
levator
Naladixic acid nucleic acid synthesis - quinolone antibacterial agent
- causes PTC
where are the greatest density of rods 20 degrees from the fovea
co-dominance both allels of a trait are expressed
what tissue is an immunologically submucosal layer of the conj
active tissue in the eyelids
independent assortment alleles that code for different traits are sorted into
the sex cells independently of one another
pleiotroy allele can display several different phenotypic
ex) sickle cell
,what is mostly associated with fes obesity
lamina cribrosa pores of healthy optic - pores are round and larger in S/I quadrants
nerve head
blepharochalasis recurrent swelling of eyelids causes them to be
baggy
- commonly in middle-aged pt
intercalary staphylomas secondary to inflammation at the junction between
iris root and cb
white dot syndroems - birdshot, serpiginous, and acute posterior
multifocal placoid pigment epitheliopathy, mmultiple
evanescent white dot syndrome, multifocal
choroiditis with panuveitis
not polypoidal choroidal vasculopathy
total staphylomas buphthalmos in congenital glaucoma
Topiramte - cb effusion = myopic shift, angle closure
Heteropolysaccharides composed of two or more monosaccharide types
ex) hyaluronic acid
how to tears in pt with dry eyes higher pH, increase osmo, decreased lysozyme
compare to normal eyes
Hydroxypropyl-guar (HP-Guar) which is a a gel-
forming matrix in Systane
indication of wet age-related ARMD cnvm, submacular hemorrhage, exudates
not drusenoid pigment epithelial detachment
, what is true when comparing topical - topical corticosteroid solutions do not require
corticosteroid solutions vs. topical shaking prior to use and are phosphate-based
corticosteroid suspensions - topical suspensions have prolonged contact time
and higher penetrations
is kcn hereditary? yes, but with incomplete penetrance
AD with incomplete penetrance
average imbibition pressure of -40 mmHg
corneal strom
when does retinal vasculature reach nasal - 8 months gestation
the nasal and temporal periphery, temporal - 1 month after birth
respectively
how to decrease spec mag +: increase n, decrease bc, h, ct
-: decrease h or n, increase ct or basecurve
morre's lightening streaks presence of brief, certical flashes of light that occur
in temporal visual field of one eye
- from acceleration of the eye or head, vitreoretinal
traction
scintillating scotoma visual aura
which layer of the cornea is most likely stroma
to poses the greatest resistance to
penetration of lipophilic drugs
double segments/double d for pt that need near line above eye level
- top of seg is automatically placed 13-14mm above
the lower seg
- upper seg should be at least 12 mm in height
ex) each seg is 12
12+12+13 = 37
