Questions and Answers 100% Solved
myopia - ✔✔nearsightedness; light focuses before the retina; trouble
seeing far objects
hyperopia - ✔✔farsightedness; light focuses beyond the retina; trouble
seeing close objects
presbyopia - ✔✔vision decline due to age; lens is less elastic; hard to focus
on close objects (think of older people holding things far away to be able to
see them)
cataract - ✔✔protein denaturation of the lens; blurry vision; lens will appear
opaque and cloudy
glaucoma - ✔✔increased IOP; results from fluid buildup; can result in
blindness; will be on meds for life
normal IOP? - ✔✔10-21 mmHg
damaging IOP? - ✔✔25-30 mmHg
what IOP is sometimes seen in glaucoma? - ✔✔60-70 mmHg

,diabetic retinopathy - ✔✔result of changes of the blood vessels of the
retina that occur over time; common cause is type 2 DM; primary focus of
care is prevention (maintain BS)
macular degeneration - ✔✔loss of central vision; can be age related;
interventions are aimed at maximizing remaining vision
which eye disorder is hereditary? - ✔✔primary open angle glaucoma
If something is stuck in the eye, which imaging assessment would you NOT
use? - ✔✔MRI- could pull out the object if metal
CT scan - ✔✔can detect tumors, bone structures, and eye muscles
slit-lamp examination - ✔✔exam of anterior eye structures (test where you
put your chin on the rest)
corneal staining - ✔✔dye is put into the conjunctival sac to point out
abnormalities of the cornea
tonometry - ✔✔measures IOP; tests for glaucoma; puff of air into the eye
flourescein angiography - ✔✔IV injection of a dye followed by serial
photographs of the retina; used for problems with retinal circulation
Electroretinography - ✔✔graphs the retinas response to light stimulation

, conjunctivits - ✔✔inflammation of the conjunctiva; can be caused by
chemical, viral, bacterial, or allergy.
Bacterial=pink eye
corneal abrasion - ✔✔a scrape or scratch of the cornea; treat right away so
it doesn't result in ulceration
corneal ulceration - ✔✔deep injury of the cornea; an emergency
Why is a Corneal ulceration considered an emergency? - ✔✔because the
cornea has no separate blood supply and infections that can permanently
impair vision develop rapidly
keratononus - ✔✔degeneration of the corneal tissue resulting in abnormal
corneal shapes; can cause corneal damage if untreated
open angle glaucoma - ✔✔results from obstruction to outflow of fluid; vision
changes are gradual; results in tunnel vision
closed angle glaucoma - ✔✔results from blocking of outflow of fluid; blurred
vision; eye redness; causes sudden eye pain and N/V; MEDICAL
EMERGENCY
strabismus - ✔✔pupils aren't focused evenly (basically cross-eyes)
nystagmus - ✔✔involuntary rapid eye movement (can be one eye or both)
