Eye Tests
How do you test vision for gross peripheral vision? - ANS-perform the confrontation test
How do you perform the confrontation test? - ANS-sit 2 feet away from pt at eye level
fully extend arms at midline and move finger up until client sees
if there is a problem, test one eye at a time
Why do you perform the corneal light reflex test? - ANS-to assess parallel alignment of
eyes
How do you perform the corneal light reflex test - ANS-hold penlight 12 inches away
from pt face and shine toward bridge of nose while client stares straight ahead
note light reflected on the corneas
What should the corneal light reflex test show - ANS-the reflection of light onto corneas
should be in the exact same spot in each eye - shows parallel alignment
What is an abnormal finding of the corneal light reflex test? - ANS-asymmetric position
of light reflection
What does the Cover test do? - ANS-looks for deviation in alignment/strength and
deviations in eye movement by interrupting the fusion reflex that normally keeps eyes
parallel
How do you perform cover test - ANS-ask pt to stare strait ahead and focus on distant
object
cover one of pt's eyes with card and observe the uncovered eye for movement
remove the card and observe the previously covered eye for movement
repeat on opposite side
What is a normal finding of the cover test - ANS-uncovered eye should stay fixed and
strait ahead, and covered eye should stay strait after card is removed
