CPOA Visual Acuity Testing 2

Question 1

What does 20/40 visual acuity mean?

Accepted Answer

The patient sees at 20 feet what a normal eye sees at 40 feet

Answer

20/40 means the patient must be at 20 feet to see what a person with normal vision sees at 40 feet.

Question 2

Which chart is most commonly used for near visual acuity testing?

Accepted Answer

Jaeger card

Answer

The Jaeger card is the standard near vision chart, rated in J-units at a standard reading distance of 14–16 inches.

Question 3

When documenting visual acuity 'cc', what does 'cc' indicate?

Accepted Answer

With correction (cum correctione)

Answer

The Latin abbreviation 'cc' (cum correctione) means the measurement was taken with the patient's corrective lenses in place.

Question 4

A patient unable to read any letter on the Snellen chart at 20 feet should be tested by:

Accepted Answer

Counting fingers at a reduced distance

Answer

When a patient cannot read the 20/400 line, the examiner tests counting fingers (CF), hand motion (HM), light perception (LP), or no light perception (NLP).

Question 5

The 'pinhole test' is used during visual acuity assessment to:

Accepted Answer

Determine if reduced VA is due to a refractive error

Answer

The pinhole occluder limits light rays to the central axis, bypassing refractive error; improvement in VA suggests an uncorrected refractive cause.
