Front 4

After what step during refraction do you balance?

Back 4

Monocular subjective

Front 5

Purpose of Balance

Back 5

To equalize the stimulus

Front 6

What are the BI-OCULAR methods of balanceing

Back 6

Blur, Red-Green, Goodwin, Cross Grid

in which balancing method do you ask which line of letters are "clearer"

Back 7

dissociated blur, goodwin

Front 8

for dissociated blur, the VAs can be/must be

Back 8

Equal

Front 9

for red green, the 20/___ line of letters is isolated

Back 9

40

Front 10

blur dissociated with ____diopters

Back 10

+0.75

Front 11

What are the BINOCULAR methods of balancing

Back 11

Vectographic and Turville

Front 12

why is it imporant to balance

Back 12

stereo acuity and fusional vergence will be decreased (possibly resulting in surgery)

Front 13

if overminused in red green, the _______ side (what color) will appear to be clearer

Back 13

green

Front 14

for dissociated, the 20/___ line of letters is isolated

Back 14

40

Front 15

in which balancing method do you ask which letters are "blacker/darker/sharper"

Back 15

red green

Front 16

if overplussed in red green, the _______ side (what color) will appear to be clearer

Back 16

red

Front 17

the room conditions in bichrome (aka red green) is/are

Back 17

dark

Front 18

for goodwin it is important that the VAs can be/must be

Back 18

equal

Front 19

for red green it is important that the VAs can be/must be

Back 19

unequal

Front 20

in goodwin, isolate the 20/___ line of letters

Back 20

20 or 25

Front 21

during goodwin, if the eyes are unbalanced, add +0.25 to which eye?

Back 21

the eye seeing the clearer image

Front 22

during goodwin, if the eyes are unbalanced after adding +0.25 to the clearer seeing eye

Back 22

remove +0.25 from the clearer seeing, and add -0.25 to the poorer seeing.

Front 23

during goodwin, if the eyes are unbalanced after removing +0.25 from the clearer seeing, and adding
-0.25 to the poorer seeing, then

Back 23

cause a .5 diopter interval by adding an addition +0.25 to the better seeing

Front 24

during goodwin, if the eyes are unbalanced after causing a .5 diopter interval by adding an addition +0.25 to the better seeing then

Back 24

remove the -0.25 (from the poorer seeing)and add an additional +0.25 to the better seeing (keeping the .5 diopter interval)

Front 25

if you have tried every single step in goodwin, and have failed at balancing their eyes, the next step is to

Back 25

redo Monocular subjective

Front 26

in vectographic, it is important that the VAs can be/must be

Back 26

unequal

Front 27

the balancing method that uses a polarized chart is

Back 27

vectographic

Front 28

for vectographic, you can fog with either ____ or ____ diopters

Back 28

+0.5 or +.75

Front 29

in alternate occlusion, isolate the 20/___ line of letters

Back 29

25

Front 30

if the eyes are unequal in alternate occlusion method, add ____ diopters to the ______ (better/poorer)seeing

Back 30

+.25, better

Front 31

this balancing method utilizes a septum

Back 31

turville

Front 32

In alternate occlusion, it is important the the VAs can be/must be

Back 32

equal

Front 33

in these balancing methods, balance is automatic

Back 33

Turville and Vectographic

Front 34

These balancing methods depend on equal acuities

Back 34

Dissociated Blur, Goodwin, and Alternate Occlusion

Front 35

In this balancing method, you instruct the patient to look at one side of the chart but keep both eyes open

Back 35

Vectographic

Front 36

these methods of balancing depend on equal rate of blurring on each eye

Back 36

Blur and Goodwin

Front 37

In these methods of balancing the patient is not fused

Back 37

cross-grid, blur, goodwin, redgreen, and alternate occlusion

Front 38

unequal pupils during this balancing method may mess up your results

Back 38

red green

Front 39

these balancing methods allow the patient to simultaneously compare 2 line of letters

Back 39

dissociated blur and goodwin

Front 40

these balancing methods require minimum blur, and are thus more accurate
