purpose of binocular balance - ANSWER Equalize the stimulus to accommodationbetween the two eyes

true or false: Binocular balance purpose includes equalizing the visual acuity between the two eyes. -ANSWER false!

accommodation is more relaxed in the - ANSWER binocular state the patient can accommodate different amounts in the _____ state - ANSWER monocular Binocular = - ANSWER both eyes open, ONE image seen one image seen with both eyes open = - ANSWER binocular both eyes open, TWO images seen = - ANSWER biocular changes the focal point without lenses (only brings focal point forward) - ANSWERaccommodation

only for patients with equal VA's; allows for successive comparison - ANSWER alternateocclusion

during alternate occlusion, you will add +0.25 to the - ANSWER clearer seeing eye alternate occlusion: you add +0.25 to the clearer seeing eye (let's say OD) now they report equality what should you do next? - ANSWER add +0.25 to OD to check for reversal. pt should now report OS is clearer Alternate occlusion:once balanced appropriately, come out of the fog _____ to BCVA OU - ANSWER binocularly a disadvantage of this test includes: a high heterophoria makes comparison moredifficult due to movement of letters - ANSWER alternate occlusion

disadvantages of alternate occlusion: - ANSWER -more difficult to make successivecomparison than a simultaneous one -high heterophoria makes comparison more difficult -undesirable to teach patient's to compare VAs in each eye simultaneous-comparison test - ANSWER vertical prism dissociation patient sees two images at the same time and compares

goal of duochrome binocular - ANSWER red and green wavelengths appear equidistantfrom the retina

this test provides an indication of the accommodative status of your patient whileviewing a near target. this test contributes to a functional analysis when over- or under- accommodation at near is suspected (younger patients) and used to find a tentative addfor a presbyope. - ANSWER FCC

when nearing the spherical endpoint during duochrome, an eye that reports the letterson the red background to be slightly clearer/darker with more defined borders may be slightly - ANSWER residually myopic (focus is in front of the retina) vergences at distance: purpose includes being able to measure through the applicationof prism, the patient's ability to use horizontal vergences to maintain - ANSWER binocular fusion duochrome test: what does it mean if the patient reports there is no change no matter what type andamount of lenses you add? - ANSWER suppression

when measuring vergences at distance: prisms, which induce retinal disparity, are gradually increased in power, forcing thepatient's ____ system to compensate for the disparity - ANSWER vergence

where to leave the person who never reports equal during duochrome? - ANSWERyoung patients : first GREEN

older pre-presby/presbyopes: last RED represents the point at which the patient has used all of their vertical vergence and canno longer maintain single vision - ANSWER break point

why do we leave older pre-presbyopes/presbyopes on the last red during duochrome ifthey do not report equal? - ANSWER helps to preserve accommodation

indicates that the retinal disparity induced by the prisms has been decreased to thepoint at which the patient can access the vertical vergence system and regain single vision - ANSWER recovery point in theory, you *CAN use the duochrome test on "color blind" individuals but you should -ANSWER use the words "left and right" instead of red and green

duochrome: some people with nuclear sclerotic cataracts will exhibit - ANSWER red bias NPC testing has the ability to evaluate both the - ANSWER convergence +accommodative system

duochrome: if green is clearer = - ANSWER patient is overminused

donder's push up target - ANSWER group of 20/30 vertical letters on fixation stick at40cm

donder's push up: begin moving the fixation stick towards the patient until they report - ANSWER firstsustained blur

donder's push up: OU results are usually greater due to - ANSWER fusional convergence retinal image size ___ as a target gets closer - ANSWER increases

donder's push up method usually generates results that are - ANSWER higher donder's pull away:put the target next to the patients eye at the vertex distance and pull away until they first report - ANSWER object is clear donder's pull away method is mainly performed on - ANSWER children those who do not understand the push up method target for minus lens to blur method - ANSWER one line above patient's best VA final results of the minus lens to blur method would be the measurement with the -ANSWER amount of minus lenses added + 2.50 needed to focus at 40cm

for the minus lens to blur method; with presbyopes you will generally need to - ANSWERadd + over the distance rx so that patient can see the target clearly

minus lens method is approx. _____ _____ than donder's push up method - ANSWER 2DLESS

Donders (binocular), donder's(monocular) and minus lens all average ____ at age 10 -ANSWER 12-14D

a patient should not use more than ___ of their amplitude for near work - ANSWER half inaccurate accommodation responses can lead to - ANSWER asthenopic complaints under accommodation = - ANSWER lag

ANSWER the patient was initially UNDERaccommodating (LAG) adding +1.50 in front of younger patients during FCC.. you have essentially just donewhat - ANSWER moved both the vertical and horizontal focal lines in front of the retina

stimulating accommodation = - ANSWER PRA if you had a high NRA value, and a low PRA value, what does this mean for the patient? -ANSWER the patient would not be able to bring anything too close, only bring it farther back. what would happen to the NRA/PRA values if you performed NRA/PRA over your FCC? -ANSWER NRA would be lower PRA would be higher (by the amount of the FCC) NRA/PRA is done with both eyes, testing how well you can relax/stimulate youraccommodation while maintaining your _____ - ANSWER vergence system

the ability of your eyes to converge - ANSWER positive relative vergence NRA relaxes accommodation and decreases - ANSWER accommodative convergence(eyes diverge)

NRA relaxes accommodation therefore your eyes will diverge so you need ____ toconverge the eyes to look at the target - ANSWER PRV

NRA depends on - ANSWER -AC/A ratio (how much you accommodate/converge) -PRV

-Latent hyperopia a latent hyperope that is not cyclopleged is essentially - ANSWER overminused if you perform NRA on a latent hyperope (who is essentially overminused), what type ofvalue will you get - ANSWER a much higher NRA value

vergence to keep things single. - ANSWER negative low PRA, occlude an eye. Pt reports target is now clear meaning which system failed? -ANSWER diverging system

low PRA, occlude an eye. pt reports still blurry meaning the - ANSWER accommodationsystem failed

expected morgan's norms for NRA - ANSWER +2.00D +- 0. if NRA value > +2.50, this could indicate - ANSWER -latent hyperope-overminused

if NRA value < +2.50 then maybe the patient has - ANSWER -poor ability to relaxaccommodation -limited PFV True or False: theoretically, if the patient has normal accommodation and normal NFV, then you shouldbe able to continuously keep stimulating accommodation indefinitely. - ANSWER true
