total blindness - CORRECT ANSWER✔✔-no light perception and no usable vision
| | | | | | | | | |
functional blindness - CORRECT ANSWER✔✔-has some light perception but no
| | | | | | | | | |
usable vision |
legal blindness - CORRECT ANSWER✔✔-having central visual field acuity of
| | | | | | | | | |
20/200 or less in the better eye with correction or a peripheral visual field of 20
| | | | | | | | | | | | | | | |
degrees or less (includes both functional and total blindness)
| | | | | | | |
keratoconjunctivitis - CORRECT ANSWER✔✔-fancy word for dry eyes; common in
| | | | | | | | | |
older adults; "sand in the eye"; typically worsens throughout the day
| | | | | | | | | | |
pathophysiology: decreases in quality or quantity of the tear film

treatment: artificial tears, ointments, closure of the lacrimal puncta
| | | | | | | |
age related macular degeneration - CORRECT ANSWER✔✔-most common cause
| | | | | | | | |
of irreversible central vision loss in people over age 60 in the US; dry or wet
| | | | | | | | | | | | | | |
,Dry AMD - CORRECT ANSWER✔✔-most common form; close vision tasks become
| | | | | | | | | | |
difficult; macular cells start to atrophy due to accumulation of yellowish
| | | | | | | | | | |
extracellular deposits in the retinal pigment epithelium called drusen; progressive
| | | | | | | | |
and painless
| |
drusen - CORRECT ANSWER✔✔-yellowish extracellular deposits in the retinal
| | | | | | | | |
pigment epithelium |
Wet AMD - CORRECT ANSWER✔✔-more severe than other form; rapid onset;
| | | | | | | | | | |
development of abnormal blood vessels in/near the macula
| | | | | | |
blood vessels grow into the retinal epithelium instead of choroid; vessels leak and
| | | | | | | | | | | |
scar tissue forms; begins as dry AMD
| | | | | | |
etiology of AMD - CORRECT ANSWER✔✔-genetic, UV light exposure, hyperopia
| | | | | | | | | |
(farsightedness), smoking, light colored eyes, nutritonal deficits (dark, green, leafy
| | | | | | | | |
|vegetables may help reduce risk) | | | |
clinical manifestations of AMD - CORRECT ANSWER✔✔-blurred or darkened
| | | | | | | | |
vision; scotomas (blind spots); metamorphopsia (distortion of vision)
| | | | | | |
scotomas - CORRECT ANSWER✔✔-blind spot
| | | |
metamorphosphia - CORRECT ANSWER✔✔-distortion of vision | | | | |
, photodynamic light therapy - CORRECT ANSWER✔✔-treatment of AMD; uses
| | | | | | | | |
verteporfin and cold laser; can be activated by exposure to sunlight and as a
| | | | | | | | | | | | | |
result the patient should avoid direct sunlight exposure for 5 days after treatment
| | | | | | | | | | | |
treatment of dry AMD - CORRECT ANSWER✔✔-inhibit epithelia growth factor
| | | | | | | | |
treatment of wet AMD - CORRECT ANSWER✔✔-destroy abnormal blood vessels
| | | | | | | | |
functional hearing loss - CORRECT ANSWER✔✔-may be caused by an emotional
| | | | | | | | | | |
or psychological factor
| |
tinnitus - CORRECT ANSWER✔✔-perception of sound in the ears where no
| | | | | | | | | | |
external source is present
| | |
conductive hearing loss - CORRECT ANSWER✔✔-occurs when conditions in the
| | | | | | | | | |
outer or middle ear impair the transmission of sound through air to the inner ear
| | | | | | | | | | | | | |
presbycusis - CORRECT ANSWER✔✔-hearing loss associated with aging
| | | | | | |
central hearing loss - CORRECT ANSWER✔✔-involves the inability to interpret
| | | | | | | | | |
sound because of a problem in the brain
| | | | | | |
mixed hearing loss - CORRECT ANSWER✔✔-a combination of conductive and
| | | | | | | | | |
sensorineural hearing loss | |
