COT EXAM STUDY-OCULAR MOTILITY QUESTIONS
WITH COMPLETE SOLUTIONS
-tropia Correct Answers turning
a manifest eye turn or deviation that the patient has no, or very
little control over. The patient is unable to keep the eye straight
with the power of fusion.
"binocular" means Correct Answers "visual properties or
processes that involve both eyes working together." Each eye
tracks the same object and each eye sees an image of the same
object.
A dissociating test is a test that presents dissimilar objects for
each eye to view, so that the images: Correct Answers cannot
be fused.
Abduction Correct Answers Movement away from the midline
of the body
,aDduction Correct Answers Movement toward the midline of
the body
, Agonist muscle action Correct Answers prime mover, directly
produces a desired movement
alternate cover test Correct Answers A test performed by
placing an occluder over one eye and then moving it slowly over
to the other eye to detect a tendency for the eyes to deviate while
under the occluder (such an ocular misalignment is known as a
phoria). Also called cross-cover test.
amblyopia Correct Answers decreased vision that cannot be
improved with refraction, that is not caused by a specific organic
problem. In other words, suppression can lead to a permanent
loss of vision.
Causes can include strabismus, congenital ptosis, congenital
cataract, refractive from high asigmatism or anisometropia or
high hyperopia
Angle kappa Correct Answers Formed between the pupillary
axis and the visual axis
Bagolini lens test Correct Answers a dissociating test used to
test retinal correspondence.
Bielschowsky head-tilt test Correct Answers attempts to
determine the paretic muscle by performing alternate cover
testing in different head positions.
This test only works in cases of a single paretic muscle.
nThe superior oblique is the muscle most commonly affected.
