Hay- Ears Flashcards
When examining the eye the nurse notices the patients eyelid margins approximate completely. This assessment finding is
expected
movement of extra ocular muscles is stimulated by 3 CNs
III
IV
VI
The outer layer of the eye is
sensitive to touch
The retina of the eye is where
light waves are changed into nerve impulses
What makes up the outer eye
cornea and sclera
stimulation of the autonomic nervous system with exam of eye
elevates the eyelid and dilates the pupil
parasymptomatic nervous system causes the pupil to
constrict
The muscle fibers of the iris contract the pupil in bright light to accommodate
near vision
The nurse is conducting a visual exam- visual pathways & fields?
The image formed on the retina is upside down and reversed from its actual appearance to the outside world
The left side of the brain interprets vision for the right eye
The nurse is testing visual accommodation
pupillary constriction when looking at a near object
normal pupillary reflex. reflex indicates
constriction of both pupils to the response of bright light
mother asks when newborn eyesight will be developed?
3 months of age, coordinated eye movement able to fixate on an object
what is responsible for presbyopia (near vision)?
loss of lens elasticity. The lens has a hard time changing shape to accommodate for near vision.
assess a 16 year old vision
Suellen chart
test for near vision
jaeger card
newspaper test
20/30 recorded on the snellen chart
pt. can read 20 feet when a person with normal vision can read 30 feet
top number distance from chart
bottom number distance a normal eye can see
pt. having a hard time with snellen
have pt. stand closer to chart but also refer to ophthalmologist
20/80 vision
poor vision
20/20 perfect vision
when to test for color vision
4-8 years old
The nurse is performing an eye screening with a 2 year old child. suspected lazy eye. what do you do to assess?
strabismus corneal light reflex test and cover test
