Q

Assymetry in amplitude of accommodation

A

Further testing would be indicated for any patient with asymmetrical amplitude of accommodation, further testing is needed if nothing in history or refraction gives suggestions

Q

FOG

A

Start at 20/40
Blur vision with plus lenses. Doesn’t have to be 6 clicks, whatever it takes to blur them. Walk them down until they just see it

A

Axis
-straddle the axis. Follow red (for minus cyl) and follow white (for plus cyl)

Q

If you want to double check your objective or subjective refractive findings (especially if the patient cannot see 20/20) what would you do FIRST

A

Pinhole

Don’t document refraction until you get the right one. If you pinhole 20/20 and need to redo it, don’t enter wrong data. Only document if you cannot get to 20/20 due to pathology that pinhole didnt rule out

Q

In the steps of a manifest refraction, which of the following is not included?

  1. Binocular refraction
  2. Relaxing the accommodation
  3. Cylinder axis and power refinement
  4. Binocular balance
A

Binocular refraction

-do this for fusion lock, do when axis is going crazy

21
Q

If you have no cylinder or axis power when you do your manifest refraction. What would you do differently than FOG
CAP
REFINE
BALANCE

A

CAP is CPAP

Do a power search every 15 degrees

22
Q

Define the interval of sturm

A

Horizontal and meridian axis—space between them!

Difference between sphere and cylinder power, bringing them closer and closer together during refraction

-3.00 -2.00 090
-5.00 @180
-3.00 @090
Difference of 2.00 is interval of sturm

23
Q

When doing a R/G test what patietns should you avoid

A

Color blind
Amblyopia
Cataracts
AMD

Any pathology really

24
Q

Give some reasons for doing a binocular refraction instead of monocular refraction

A
  • nystagmus
  • anisometropia (different powers in eyes)
  • non suppressing tropia (usually intermittent)
25
Q

What is the purpose of electronic health records

A
  • increases reimbursement levels from insurance providers
  • makes transfer of knowledge easier

Nothing to do with diagnostic skills

26
Q

What is amp ACC

A

Maximum focusing ability

27
Q

What is amp response

A

Over or under acc

28
Q

What is the amp facility

A

Speed or elasticity

29
Q

What is the accommodative insufficiency

A

Don’t have enough AAC

30
Q

How do you measure Amp ACC

A

NRA and PRA

31
Q

How do you measure amp response

A

Near retinoscopy

-over or under accommodation

32
Q

How do you measure amp facility

A

Flippers

33
Q

The comfortable range of accommodation is determined by what formula using Amp ACC

A

Half amp ACC

34
Q

Amp of accommodation based on age is calculate by? Minimum

A

15D-0.25(age)

35
Q

Amp of accommodation based on age is calculated by? Mean

A

18.50D-0.30(age)

36
Q

Amp of accommodation based on age is calculated by? Max

A

25.00D-0.40(age)

37
Q

Give some reasons for a unilateral decrease in a patients amp of ACC

A
  • anisocoric (unequal pupils)
  • inflammation or trauma of the ciliary body
  • improperly balanced manifest

NO ORAL ANTICHOLINERGIC

38
Q

When you do a manifest and your patients acuity is 20/40 OD OS but pin hole is 20/20 OD OS, what should you do?

A

Redo it

39
Q

Using the minus lens technique for amp ACC the patient reaches sustained at blur at -1.50D. You are working at 40cm, what is the Amp ACC?

A

40cm=2.5D

1.50+2.50=4.00D

40
Q

It be unwise to measure amp ACC on a patient with?

A

Presbyopia

41
Q

Based upon age appropriate prescribing for presbyopia, what would you prescribe a

A 
30-none
40- +1.00
50-+2.00
60- +2.50
70- +2.50
42
Q

What is the appropriate endpoint for a bino balance

A
  • perceived equality between the eyes

- dominant eye better when equality can not be achieved

43
Q

When you have no cyl axis or power in the manifest model you do

A

FOG
CPAP
Refine
Balance

44
Q

During a manifest refraction, your patient starts to show fatigue and is running you all over the place. What are some options to find the most accurate manifest refraction

A

Cyclo

45
Q

NRA is measured with _____ lenses

A

Positive

46
Q

PRA is measured with _____ lenses

A

Negative

47
Q

convergence demands remain constant and accommodative demands change

A

NRA and PRA

48
Q

What is the most common method used for prescribing for presbyopia

A

Age, because time is money

49
Q

What is your responsibility in educating the patient when it comes to the lenses that my choose to purchase

A

Just as important as Tx glaucoma, AMD, etc. we know what it takes to keep comfortable. Tell them what you think is best
