Vision and contact precautions Flashcards
emerge from coma, assessing
oculomotor control
Hemianopsia
visual cut field, anchoring
diplopia
double vision, eyepatch
common with MS
visual closure
difficult to see things that are partially covered
fill in the blanks, connect the dot, forming letters
low vision interventions
lights, decrease glare, increase contrast
strengthen other senses
standard precautions
- hand hygiene before and after contact (sanitizer, soap and water with C-Diff)
- PPE if contact with blood or body fluids may occur (gown, gloves, eye/mouth protection)

3. limit movement and transport of patient to essential purposes only
contact precautions
in addition to standard precautions
1. isolation room
2. gloves and change when needed
3. gown and change when needed
4. single patient use equipment
use of magnifiers
NOT indicated for certain scotomas because it may enlarge images into the non seeing portion of the macula
proliferative diabetic retinopathy
advanced form of the disease, new blood vessel growth in the retina and leakage, scar formation, and possible retina detachment
*may lead to total blindness
presbyopia
visual loss in the middle and older ages; inability to focus properly, blurred images
due to loss of accommodation, diminished elasticity of lens
age related macular degeneration (AMD)
macula - part of the eye that allows you to see fine detail
appears as a “blank spot” in the central visual field called a scotoma
cataracts
clouding of lenses - blurred vision, difficulty reading in bright light, can use peripheral vision (central loss of vision goes first)
glaucoma
peripheral vision goes first (tunnel vision)
Difficulty locating desired items, like a can of soup in the pantry
visual scanning deficit
