COA Practice Exam
While performing an automated visual field test, your patient has 2 or more false negatives. The best
course of action is:
a. Make sure the fellow eye is patched properly
b. Let the patient take a break
c. Remind the patient to look only at the fixation light
d. Increase the stimulus size - ✔✔ correct answer b. Let the patient take a break
As you are instructing a patient how to take an automated visual field test, the patient states they
cannot see the fixation light. Your next step would be:
a. Tape the patient's upper eye lid
b. Increase the stimulus size
c. Change the fixation target to a diamond
d. Remove the patch from the fellow eye - ✔✔ correct answer c. Change the fixation target to a
diamond
Which of the following instructions are important to tell patients when performing an automated
visual field test?
a. Tell me when you see a light
b. Push the button when you see very bright lights
c. Do not blink during the test
d. Push the button when you see any light
e. Be sure not to miss any lights - ✔✔ correct answer d. Push the button when you see any light
A patient doesn't push the response button when a light is presented to him during an automated
visual field test. A light is again presented to the patient in the same point of the visual field only this
time it's a brighter light. This is an example of:
a. Kinetic VFT
b. Threshold VFT
c. False negatives
d. Fixation loss - ✔✔ correct answer b. Threshold VFT
A patient responds to light that is presented with a visual field machine has already determined his
Blindspot is. This is an example of:
, COA Practice Exam
a. A false negative
b. Kinetic VFT
c. Threshold VFT
d. A fixation loss - ✔✔ correct answer d. A fixation loss
A patient who is performing an automated visual field test has multiple fixation masses and false
positives. This is likely due to
a. Anxiety
b. Fatigue
c. Dense visual field defect
d. A lens rim artifact - ✔✔ correct answer a. Anxiety
If an automated visual field machine cannot locate the patients Blindspot the best course of action is
to
a. Repeat the "blind spot check"
b. Make sure the fellow eye is properly patched
c. Reinstruct the PT
d. All of the above - ✔✔ correct answer d. All of the above
When performing a kinetic visual field testing it's important to
a. Move the stimulus quickly
b. Move the stimulus from a non-seeing area to a seeing area
c. Instruct the patient to be certain the stimulus is present before responding
d. Map the nasal field first - ✔✔ correct answer b. Move the stimulus from a non-seeing area to a
seeing area
The main difference between static and kinetic VFT is
a. One is automated and the other is manual
b. One tests only the central 10º of VF while the other tests the central 30º of VF
c. When is performed with a moving stimulus and the other with a stationary stimulus
d. When is considered a gross assessment of the visual field and the other is a formal methods of
visual field testing - ✔✔ correct answer c. When is performed with a moving stimulus and the other
with a stationary stimulus
