◉ This is due to lack of foveal development at birth and packing of
cone photoreceptors over the 1st 3 years.
Answer: At birth, VA's are 20/200 and approach 20/20 within 3
years. Why is this the cause?
◉ fusion.
Answer: process where 2 eyes images are combined into single
perception
◉ motor and sensory.
Answer: Name the 2 types of fusion
◉ motor fusion.
Answer: use of vergence eye movements to position the eyes to
corresponding points
◉ sensory fusion.
,Answer: neurophysiological/psychological process of combining 2
images in visual cortex
◉ version
EOM's.
Answer: binocular movement or rotation of eyes in same direction
Name an example of a test we do in lab
◉ vergence
cover test.
Answer: binocular movement of eyes in opposite direction
Name an example of a test we do in lab
◉ deviation.
Answer: difference in eye position between the 2 eyes
◉ phoria or heterophoria.
Answer: deviation that can be compensated for with vergence
movements; cannot be seen without breaking fusion first
◉ tropia or strabismus.
,Answer: deviation that can NOT be compensated for with vergence
movements; no need to break fusion
◉ comitant.
Answer: Deviation is same in all gazes of fixation
◉ noncomitant.
Answer: deviation greater in different fields of view
◉ due to unequal innervation/muscle tone to each EOM
(can lead to signs of diseases like stroke, tumors, trauma, and
congential diseases).
Answer: What is the reason for noncomitant deviations?
◉ constant.
Answer: when tropia is always present no matter the condition
◉ intermittent (can depend on viewing condition, or how tired Pt
is).
Answer: when tropia is sometimes present, sometimes not present
◉ alternating.
, Answer: when tropia is sometimes present in right and other times
in the left
◉ A single letter one line larger than best VA for worse eye.
Answer: How do you set the chart for cover test for distance?
◉ with correction, stand light on the card
one line above worst VA (single letter)
(usually 20/25 on letter H).
Answer: How do you set cover test for near?
◉ tropia vs phoria.
Answer: Cover and uncover test can test for what?
◉ magnitude and direction.
Answer: Alternating cover test tests for what?
◉ Eso, eso.
Answer: Hyperopes are far more likely to have an ___ position at
distance and even MORE _____ at near
◉ ortho, exo.
