improvement and enhancement of accommodative function, ability to identify objects at different distances under different dioptric demands, and increase range of function and allow for flexibility with other visual skills

Q

What does -1.00 OU do to the accommodative/vergence system?

Q

How do you train speed?

A

work on improvement in how fast patient can make the change; using lenses–change between plus and minus, increasing speed; using distance– change between near and far, increasing speed

25
When do you emphasize speed?
after accuracy, remember practice makes permanent
26
During speed, patient should focus on...
rapidity of accommodative response, patient should feel the effort
27
What is accommodative range?
ability to use the full amount of accommodation that is normal for the patient's age
28
What accommodative dysfunction is range particularly important for?
AI
29
How is range measured clinically?
amplitude testing, push-up/pull-away or minus lens amplitude
30
How is range calculated?
Hofstetter's formulae
31
What are two ways to train range?
using lenses and using distance
32
How does using lenses train accommodative range?
increase the amount of lens power, higher minus= more amp needed
33
Why do you need to consider the working distance for using lenses to train accommodative range?
high plus is problematic because the working distance moves toward the nose, maximum plus +3.00
34
How does using distance train accommodative range?
increase/decrease working distance because closer=more amp needed
35
Why should you be hesitant to change too much of accommodative range during a VT session?
too rapid often= poor maintenance of gains, the exception is when the activity needs to be easier
36
What are examples of accommodative range activities?
increase lens power in MAR/BAR/loose lens rock, increase distances during NFHC, increase range of powers during lens sortin
37
What is accommodative stamina?
the ability to maintain accommodative state over time
38
What accommodative dysfunction is stamina particularly important for?
AI/ill-sustained accommodation
39
T/F stamina is not measured directly in clinical setting
true, only indirectly
40
How is stamina indirectly measured in a clinical setting?
facility– does the patient fatigue over time, amplitude– does the amp change throughout the exam, near VA– does the near VA change throughout the exam?
41
How can you train accommodative stamina?
perform accommodative therapies for an extended period of time and increase accommodative demand throughout the therapy activity
42
How can you increase the accommodative demand throughout the therapy activity?
increase minus lens power, increase lens range, increase distance range
43
When should you emphasize stamina?
throughout the VT program
44
When should you emphasize range?
emphasize each week with changes
45
What are examples of increasing accommodative stamina?
perform MAR for at least 5 minutes per eye, perform at least 10 cycles (blur-clear-blur) per lens on mental minus, complete entire chart multiple times with each eye on NFHC
46
What direction should you work in?
the direction of difficulty first (after determining current ability) aka focus on relaxing with AE/spasm and focus on stimulating with AI
47
Which comes first, accuracy or range?
accuracy
48
Which comes first, range or speed?
range, greater amps before greater facility
49
What do you need to emphasize during all accommodation therapy?
the FEELING of accommodation, hard when stimulating, soft when relaxing
50
What are examples of physiological feedback for look hard/soft?
shoulders scrunched, muscles tight, brow furrowed, etc
51
How do you know if the patient is fatiguing?
performance slows over time
52
Do you care about diplopia during accommodative tasks?
yes! Is the patient supposed to be double? (bi-ocular) or can you do anything to make the target single again?
53
What are the general accommodative feedback mechanisms?
feeling, fatigue, diplopia, suppression, SILO, and blur
54
With minus lenses, the patient should perceive...
small/in
55
With plus lenses, the patient should perceive...
large/out
56
What does blur tell you during accommodative therapy?
patient is over or under-using accommodation
57
How can you make accommodative therapy easier?
decrease range, increase print size, move the working distance further
58
How can you make accommodative therapy more challenging?
increase the range, decrease the print size, change the working distance
59
Therapy must be...
patient driven
60
How can you keep vision therapy patient driven?
have the patient hold targets and flip lenses when appropriate, emphasize the feeling of changes, and allow for success
61
You need to spread out your activities over the major visual skills for oculomotor and accommodative VT, those skills are...
accommodative, oculomotor, gross motor
62
What are the feedback mechanisms from the review points?
motor overflow, blur, diplopia, visual awareness
63
What is the order of accommodative improvement?
ability/accuracy --> speed --> range --> stamina
