1

the ability to receive sensory input and, through various physiological processes in the body, translate the stimulus or data into meaningful information

sensory perception

2

a deficit in the normal function of sensory reception and perception

sensory deficit

3

what are 3 types of sensory deprivation

reduced sensory input
elimination of patterns or meaning from input
restrictive enviornments

4

what are 5 characteristics of cataracts

1. cloudy, opaque lens
2. decreased visual acuity
3. no pain
4. occurs gradually
5. decreased night vision

5

what are the treatments for cataracts

removal of lens with lens implant

6

an opacification (clouding) of the lens, that can significantly interfere with light transmission to the retina and the ability to perceive images clearly

cataracts

7

blindness

8

what are cataracts risk factors

aging
blunt trauma
genetics
environment
long term sun exposure
smoking and alcohol use
ocular inflammation

9

what are clinical manifestations of age related cataracts

cloudy/opaque lens
cloudy vision
halos
diplopia
photophobia

10

what are the 4 subjective data of early stage cataracts

blurred vison/decreased vision acuity
sensitivity to light or glares
halo around lights
does NOT hurt

11

what are the 4 objective data late stages

progressive loss of vision
diplopia
visual opacity
absent red reflex

12

what are the diagnosis studies for cataracts

history and physical examination
visual acuity measurement
opthalmoscopy
slit lamp microscope
glare testing

13

there is not a surgical "cure" for this

cataracts

14

what visual aids may help cataracts

changing eyewear prescription
reading glasses
magnifiers
increased lighting

15

where do cataracts typically start

in the periphery

16

cataracts usually will happen ________ but one progress more than the ______

bilaterally; other

17

a cataract that takes up the entire lens is

mature

18

a cataract that takes up just half of the lens is

immature

19

topical or systemic long term corticosteroids increase risk of

cataracts

20

what develops cataracts at a younger age

uncontrolled diabetes

21

what do the glare testing and slit lamp light do

see back of eye and make sure there are not any protein clumps for cataracts

22

what happens during the preoperative phase of cataracts

H&P
Eye drops (no steroidal anti inflammatory, dilating)

23

what are the steps of the intraoperative phase of cataracts

corneoscleral incision
cataract extracted and sutures
cortex irrigated and aspirated
corticosteroid and antibiotic ointment

24

why will the steroid does be low and short term for cataract sx

because they typically cause cataracts

25

if the eyesight is not better post op it should become better __-__ days after surgery just because the eye is _____ form surgery

3-5; irritated

26

if there is redness after cataract sx this could be

sign of infection

27

after cataract sx avoid bending over because

it could cause pressure

28

what vitamins should be taken for cataracts

A, E, C

29

what assessment should be done post op

check visual acuity
psychosocial impact of visual acuity
level of knowledge about sx
comfort/ability to comply with post treatment
self care deficits
anxiety

30

what are 5 signs of complications after cataract sx

sharp, sudden pain in eye
bleeding or increased discharge
lid swelling
sudden decrease in vision
flashes of light that might increase IOP
