Red eye Flashcards
vascular layer that lines posterior eye
choroid
right behind ciliary body and lens, fluid flows between it and anterior chamber
posterior chamber
allows for movement b/w posterior and anterior chamber
ciliary body
where we see increased vasculature
conjunctiva
lined with epithelial cells (thin layer)
cornea
measure of intraocular pressure
tonometry
how to examine eye, in place of pen light exam
slit lamp
what we want to look at with red eye
visual acuity, tonometry, slit lamp/ pen light
OD
right
OS
left
OU
both
age related focus dysfxn, loss of near vision
presbyopia
CF
count fingers
how far can they see your fingers (how many am i holding)
CF
HM
hand motion
LP
light perception
NLP
no light perception
more than 30 need to be seen ASAP
intraocular pressure
tonometry normal measure is ___ IOP
8-21
tonometry measures from __ to ___
0 to 80+
six parts you look at with red eye
lids/lashes, conj/ sclera, cornea, ant chamber, iris, lens
meibomian gland dysfxn
blepharitis
MGD
meibomian gland dysfxn
chronic itching, burning, scratchy, worse in the AM, no vision decrease erythema, scales, debris
blepharitis
EES
erythromycin
management of blepharitis
warm compress, baby shampoo, abx
abx for blepharitis
bacitracin and EES ointments, aztirhromycin soln, oral abx (if topical ineffective), opthalmologist if not improving (they prescribe corticosteroid gtts
___ contributes to dry eye syndrom
blepharitis
dry eye syndrome
deficient aqueous tear production
chronic itching, burning, scratchy, “tired” eyes, esp in PM
sxs of dry eye syndrome
vision fluctuation, poor tear film (possibly due to MGD), puncturate epithelial erosions (slit lamp), + schirmer test
signs of dry eye syndrome
dry eye tx
artificial tears/ ointments, opthamology referral
ophthalmologist tx of dry eye
topical cyclosporine, +/- topical steroids, punctual plugs
poor tear films lead to
surface problems
infected eyelash root
hordeolum
PAINFUL, sweling common, may affect entire eyelid
hordeolum
hordeolum tx
warm compress, abx, steroid injection, +/- surgical drainage
caused by clogged oil gland (MGD)
chalazion
TYPICALLY NOT PAINFUL unless very large, rarely does it make the entire eyelid swell
chalazion
chalazion tx
warm compress, abx prn, steroid injection, +/- sx drainage
inflammation of lacrimal gland
dacryoadenitis
viral or bacterial source: mumps, EBV, staphylococcal, gonococcal
acute dacryoadenitis
noninfectious inflammatory disorders, thyroid disease, orbital pseudotumor
chronic dacryoadenitis
swelling of outer upper lid, pain in area of swelling, +/- erythema, epiphora, preauricular LAD
dacryoadenitis
daryoadenitis dx
CT if etiology is unclear, bx if concern for tumor
viral dacryoadenitis tx
warm compress
dacryoadenitis tx for bacterial/ other causes
treat underlying cause
clear thin tissue that covers part of the sclera, unknown causes (maybe irritation/ sun), associated with aging, usually does not cause vision loss
pinguecula
pinguecula tx
lubricating drops, sunglasses, +/-cosmetic sx, vision sx
pinguecula can progress to
pterygium
thickening of the bulbar conjunctiva that grows slowly across the outer surface of the cornea, usually on the nasal side, may interfere with vision as it encroaches upon the pupil
pterygium
pterygium tx
lubricating dros, sx prn vision changes
