Q

What happens with insurance if the rehab prognosis is poor?

A

Insurance may stop paying if their condition will not improve

17
Q

What to document when taking VA

A

VA
Type of chart
Lighting
VF status- presence of eccentric viewing/head turn or tilt.
***For legal blindness, eccentric viewing is not allowed.

18
Q

Metric notation at near

A

Linear

1M= 1.45mm optotype = 20/50 = 8 point = newspaper print

19
Q

1m/1M = what snellen

A

20/20

1M subtends 5 min of arc at 1 meter

20
Q

EOM modifications

A

Slower
Use pt’s finger
Tell them which gazes to look in
Turn their head- doll

21
Q

Color VA testing

A

Jumbo D15 test plates.

Konan test on the computer can adjust size of stimulus

22
Q

Color vision deficiency found in __% of low vision pts.

What % due to ON disease and what % due to retinal pathology?

A

48.8%

62% bc ON
51% bc retina

23
Q

CVF modification

A

For extent of field, use vision disc. Cannot be used for legal blindness certification tho

24
Q

Which add to use with amsler

A

+3

25
Q

Common conditions with high cyl

A

Albinism, aniridia, KCN, nystagmus

26
Q

Cyl refinement

  • What target to use?
  • Which JCC to use based on VA?
A

Use target 2 lines larger than VA found with sphere power

+/- 0.50DC if VA is 20/30-20/50
+/- 1.00DC if VA is 20/200 or worse

27
Q

Axis refinement

A

Make 15 degree jumps initially
Then add power
Repeat axis refinement with smaller degree changes (10 and 5)

28
Q

Sequence of refraction

A
  1. Take initial VA through starting point. Calculate VA
  2. Sphere check. Change JND throughout if VA improves.
  3. Cyl refinement/probe
  4. Check VA and recalculate JND
  5. Sphere refinement
29
Q

Refractive errors:

Albinism 
K scarring 
Pendular nystagmus 
Cataracts 
Down syndrome 
ROP
Cerebral palsy 
Microphthalmos 
Diabetes
A 
Albinism- high refractive error and WTR astig
K scarring- astig 
Pendular nystagmus- WTR astig 
Cataracts - myopia
Down syndrome- Myopia 
ROP-Myopia 
Cerebral palsy - hyperopia 
Microphthalmos - hyperopia 
Diabetes -Shifts
30
Q

When to do binocular vision testing

A

Those whose VA differs no more than a factor of 1.5

Ex: 20/40 and 20/60

31
Q

Importance of binocularity

A 
Psychological importance 
Enhance acuity 
Larger VF 
Better contrast 
Better depth 
May stabilize eye alignment
32
Q

Binocular testing

A
  1. Worth 4 dot- 4 circles seen
  2. Maddox rod- see pink line.
  3. 4 prism test. Twist and see if they notice diplopia
33
Q

5 emotional stages of loss

A
  1. Shock/denial
  2. Anger
  3. Depression
  4. Bargaining
  5. acceptance
34
Q

Denis Diderot wrote a letter on the blind and was thrown in jail. When did attitudes change about blind?

A

1800s - schools started to open and brail was invented

35
Q

Low vision depression prevention trial for ARMD (VITAL)

A

Demonstrated improvement in depression scales with LV rehabilitation. Pts working towards goal improved depression

36
Q

SPIKES approach for delivering bad news

A 
S- set up the interview 
P- look at pt's perception 
I- Ask for their invitation 
K- Share knowledge 
E- address emotions 
S- Summary and plan
37
Q

A
  • Pleasant, humorous images.
  • At times of rest
  • Prevalence increases with age. 10% report to providers. Half given info about syndrome.

Tx:

  • Change visual activity
  • Talk to hallucinations
  • SSRIs
