1 Seizure 2 Intraocular Pressure (IOP)
3 Eye Trauma 4 Astigmatism
Don't know?
Terms in this set (128)
Intraocular Pressure (IOP) 10-21!
-pressure that it atkes to push the cornea to lens
-> 21= glaucoma
,Myopia nearsightedness
d/t: excessive light refraction, abnormally long eye,
lens swlling and can increase during growth spurts
Hyperopia farsightedness
d/t: inadequate focusing power and eyeball too
short either growing issue or the way they were born
Presbyopia hyperopia that occurs d/t aging (bifocals/trifocals)
Astigmatism corneal curvature
LASIK Surgery flap of cornea is folded back and the layers are
removed
-little pain!
PRK Surgery reshaping the cornea with laser
better for thin cornea or worse myopia
decrease IOP (do not bend over, don't pick up over
5lb, manage coughing, sleep 30-40 degrees)
Hordeolum infection of the gland in the lid
red, swollen, tender, rapid
warm moist compress (qid), don't use makeup, lid
scrub 1 tsp baby shampoo and 1 pint water, abx
Conjunctivitis infection of conjunctiva
-bacterial: mucopurulent discharge/discomfort
(tx: abx, handwashing, handle drainage carefully,
warm compress)
-viral: itching/burning/ foreign body sensation,
URI/post-swimming, self-limiting (tx: steroid drops if
continues)
Bacterial Keratitis infection of cornea
tx: topical abx (2)
, Viral Keratitis HSV-1
most common infection to cause blindness
tx: antivirals
topical corticosteroids are contraindicated!
Varicella Zoster Keratitis reactivation of varicella zoster
tx: pain meds, topical corticosteroids, antivirals,
mydriatics, topical abx for secondary infections
Eye Trauma chemical/irritant: irrigate with saline/sterile water
non-irrigating: patch BOTH eyes
foreign object: don't remove, HOB elevated, pain
meds, NPO d/t impending surgery
Cataracts opacity in the lens
-both or one eye
-s/sx: dec vision, abnormal color perception, GLARE,
whitening lens
-dx: glare test!
-tx: increase lens prescription, lifestyle
-surgery: remove/replace lens
-nursing: decrease infection, pain mgmt, decrease
IOP, medication
Retinal Detachment separation of retinal and epithelial layer
s/sx (FFR): flashes light, floaters, ring in vision field
-when detached: painless loss of vision
(central/peripheral)
-preop: mydriatics, cycloplegic
-postop: topical abx, topical steroids, pain meds,
mydriatics
Dry Macular Degeneration slow and painless
Wet Macular Degeneration rapid and painful
