COT Visual Fields Questions With Complete Solutions
"At threshold" means that the patient responds to a given
stimulus in the same area: Correct Answers 50% of the time
A "normal" screening test means that: Correct Answers The
patient has no field defect detectable by this test
A patient might not respond to a suprathreshold stimuli: Correct
Answers By chance
Accurately determining threshold requires: Correct Answers
Multiple testing of the same point
Advantages of the Autoplot® include all of the following
except: Correct Answers Testing distance can be varied
Advantages of the Goldmann perimeter include all of the
following except: Correct Answers Its portability
After leaving the optic tract, the nerve fibers bundle together at a
"relay station" known as the: Correct Answers Lateral
geniculate body
An advantage to manual perimetry over automated is that
manual perimetry: Correct Answers Permits testing of the entire
visual field
An area inside a visual field isopter that does not respond to any
of targets available on that particular machine is termed a:
Correct Answers A scotoma is an area within an isopter where
, vision is impaired or absent. The definition gives (ie, no
response to any stimulus on the particular machine) actually
refers to an absolute scotoma. Bjerrum's is a particular type of
scotoma that extends from the blind spot/optic nerve.
An automated single intensity screening program determines a
few threshold values, extrapolates the individual's island of
vision, then: Correct Answers Tests point with a supposed
suprathreshold stimulus
An object on the patient's right will be perceived by the patient's:
Correct Answers An object on the patient's right will stimulate
the temporal retina of the left eye and the nasal retina of the
right eye. The foveae (plural of fovea) are used during central
fixation, not for peripheral vision.
Arc perimetry is most useful for: Correct Answers Plotting
outer isopters
As the nerve fibers pass through the optic tract, they: Correct
Answers Rotate, thus changing position
At the chiasm: Correct Answers At the chiasm, the nasal fiber
from each eye cross over the other side. The temporal nerve
fibers do not cross, but remain on the same side.
Automated threshold testing: Correct Answers Measures
sensitivity at each tested point
Automated threshold tests generally start with a suprathershold
stimulus, then: Correct Answers Automated threshold tests
