1 / 24

Which equipment is needed for near visual acuity testing?

Transilluminator only

*Near point visual acuity card and near card attachment for phoropter

Snellen chart only

Penlight and cover paddle

2 / 24

What is the purpose of near visual acuity testing?

To assess distance vision accuracy

To measure peripheral vision

To test color vision

To identify the smallest object seen on a near point visual acuity card

3 / 24

What should be documented if the patient does not seem to understand the instructions?

Repeat the test without documentation

Skip the test

Assume the result is normal

Document the lack of clarity in understanding

4 / 24

Pinhole testing always improves a patient’s vision.

True

False

5 / 24

What does improvement in vision with a pinhole test usually indicate?

A need for surgery

Cataract development

A correctable refractive error

Permanent vision loss

6 / 24

If a 200 E chart is used at 4 feet, how should the result be recorded?

200/4

4/200

20/200

200/20

7 / 24

Why is the numerator usually 20 in standard vision testing?

Vision charts are calibrated or measured 20 feet away from their eye

It's a random convention

20 inches is the standard chart size

20 is the normal number of letters on a chart

8 / 24

What does a result of 20/40 mean?

The patient sees clearly at 40 feet

The patient has better than normal vision

The patient sees at 40 feet what a normal person with 20/20 vision sees at 20 feet

The patient sees at 20 feet what a normal person with 20/20 vision sees at 40 feet

9 / 24

If the patient needs to move the card closer than 14 inches to see better, what adjustment should be made?

Decrease the add power for near vision

Increase the add power for near vision.

Use a different card

Test distance vision instead

10 / 24

If the eye is uncentral, unsteady, and unmaintained, how should it be recorded?

CSUM

UCUSUM

UCUM

None of the above

11 / 24

During CSM testing, what is the first step?

Ask the patient to follow a light

Cover both eyes simultaneously

Observe which eye is fixating straight

Ask the patient to blink repeatedly

12 / 24

What does CSM stand for in vision testing?

Central, Steady, Maintained

Central, Strong, Maintained

Central, Steady, Motion

Corrected, Stable, Monocular

13 / 24

If the patient can fixate but does not follow the object, how should you document it?

No response

F&F

Fix, no follow

CSM negative

14 / 24

What are you encouraging the patient to do during F&F testing?

Blink repeatedly

Squint at the light

Fixate on the target

Cover one eye

15 / 24

What type of object should be used to assess Fix and Follow?

Any object in the room

A small bright toy, light, or your face

A vision chart

A finger only

16 / 24

What is critical if a patient is being documented as No Light Perception (NLP) for the first time?

The room lights must be turned on

The patient must wear corrective lenses

A provider must verify the result

A second test must be done immediately

17 / 24

What should be recorded if a patient can see light and determine its direction?

LP

LPD

LPw/P (Light Perception with Projection)

NLP

18 / 24

What does "EF" or "Ecc" indicate in CF testing?

Eye fluttering

Extreme focus

Eccentric fixation (e.g., head tilt or peripheral use)

Eye fatigue

19 / 24

When using Counting Fingers (CF), how should results be documented?

As the number of fingers seen

As CF@X FT or CF@X INCHES

As FT/X CF

As X/200

20 / 24

When assessing Hand Motion (HM) vision, what should you do if the patient cannot detect the hand motion?

Repeat the test using both hands

Skip to Counting Fingers (CF)

Move forward instead of backward

Proceed to Step #4 (Light Perception)

21 / 24

What is the most important factor when choosing the vision chart?

The patient’s language and ability

The brightness of the screen

The size of the room

The eye color of the patient

22 / 24

How should each eye be tested?

Test both eyes at the same time

Test only the dominant eye

Test each eye separately, starting with the right unless contraindicated

Only test the left eye unless there’s a reason to test the right

23 / 24

What should be done to the room lights during the test?

Dim the room lights

Keep them at full brightness

Turn them off completely

Use colored lighting for contrast

24 / 24

Before beginning the vision test, what should you ensure regarding the patient’s eyewear?

Ask them to remove all eyewear

Test them without any correction

Only use their correction for the left eye
