Deck 16: Managing Visual and Visuospatial Impairments to Optimize Function

Question 1

The most appropriate acute intervention for those with diplopia is:

A) full unilateral visual occlusion.
B) partial visual occlusion.
C) orthoptics.
D) "pencil push-ups."

Answer 1

B
Proper use of partial occlusion can result in comfortable single vision without the negative side effects of full occlusion,particularly preserving peripheral vision.The "spot patch" is one type of partial visual occlusion.It is a round patch made of translucent tape that is placed on the inside of the client's glasses (corrective or nonprescriptive lens)and directly in the line of sight.Another suggested method for partial visual occlusion is to apply a strip of opaque material such as surgical tape to the nasal field of one eye (i.e.,the peripheral field is left unoccluded)over prescriptive or nonprescriptive glasses.

Question 2

Difficulty reading may be due to impaired:

A) saccades.
B) divergence.
C) spatial relations.
D) none of the above.

Answer 2

A
This term refers to the ability to quickly and accurately look or scan from one object to another,such as reading lines of text.

Question 3

A strabismic disorder results in:

A) overreaching.
B) underreaching.
C) avoidance of near tasks.
D) all of the above.

Answer 3

D
Problems regarding judging depth and distance occur when strabismus is present.In addition,resultant diplopia makes near tasks such as reading difficult.

Question 4

Interventions for those living with decreased visual acuity include:

A) increasing illumination.
B) increasing contrast.
C) increasing size.
D) all of the above.

Question 5

The skill used to change the focus of the eye so objects can be seen at different distances is:

A) acuity.
B) ocular range of motion.
C) accommodation.
D) vergence.

Question 6

Threading a needle successfully requires intact:

A) depth perception.
B) color perception.
C) divergence.
D) saccades.
