BRS Evaluation of Visual Impairment 2

Question 1

When assessing contrast sensitivity in a patient with low vision, which spatial frequency range is most critical for face recognition?

Accepted Answer

Mid spatial frequencies (3–6 cpd)

Answer

Mid spatial frequencies (3–6 cycles per degree) carry the critical information needed for recognizing faces and many functional tasks.

Question 2

A BRS practitioner uses the Pepper Visual Skills for Reading (PVSR) test. What does this test primarily assess?

Accepted Answer

Eccentric viewing stability and reading efficiency with low vision

Answer

The PVSR assesses whether a client can use eccentric viewing effectively and measures reading efficiency relevant to low vision rehabilitation.

Question 3

Which of the following best describes 'crowding' (contour interaction) in the context of visual impairment evaluation?

Accepted Answer

Decreased letter recognition when flanking letters are placed nearby

Answer

Crowding refers to impaired recognition of a target letter or symbol when flanking elements are placed in close proximity, commonly seen with eccentric viewing.

Question 4

A functional vision evaluation documents that a client has a 'preferred retinal locus' (PRL). Which statement about PRL is most accurate?

Accepted Answer

A PRL is an area of intact or relatively intact retina used in place of a damaged fovea

Answer

A PRL is a retinal area outside the damaged fovea that the patient habitually uses for fixation, and it can be identified through both microperimetry and careful behavioral observation.

Question 5

During an evaluation, a client reports difficulty reading standard print but can read with a CCTV. This finding most directly informs which rehabilitation need?

Accepted Answer

Need for electronic or optical magnification for near tasks

Answer

Success with a CCTV indicates the client can benefit from magnification technology for near tasks, guiding prescription of optical or electronic low vision aids.
