Strabismus-Ocular Motility Questions
And Correct Solutions| 2026 Update|
Verified
An examiner could use a_________While testing versions. The patient can
tell the examiner if the red/white light separates at any point to see if an
incomitant deviation is present - Ans--Red lens
Strabismus can include: - Ans--•Accommodative strabismus
•Alternating strabismus
•Comitant strabismus
•Incomitant strabismus
•Latent strabismus
•Paralytic Strabismus
Causes/risk factors of strabismus can include: - Ans--•Family history of
strabismus
•Refractive error
•Medical conditions
Accommodative strabismus - Ans--Caused by focusing efforts of eyes
trying to see clearly, highly influenced by accommodative effort. Example:
accommodative Esotropia
Focusing on a stimulus at near causes: - Ans--Miosis, accommodation,
convergence
Miosis, accommodation, convergence, is known as; - Ans--Synkinetic near
responsel
What eliminates physiologic diplopia? - Ans--When we look at an object in
the distance of 20 feet or more, without refractive error, there is no
accommodative demand. Without accommodative demand, there is no
convergence response. As an object or stimulus moves closer to us, the
, image falls behind the retina appearing blurred and causes the ciliary
muscles to contract, accommodation. The image falls temporarily on the
retina causing the medial rectus muscles to contract, converge,To bring the
image in focus on the retina.
Types of accommodative esotropia include: - Ans--•Refractive
•Non-refractive
•Partially accommodative
Refractive esotropia - Ans--A type of accommodative esotropia that
includes:
•hyperopia (uncorrected), •accommodative convergence,
•poor fusional divergence
Non-refractive Esotropia - Ans--•A type of accommodative esotropia that
includes high ratio of the accommodative convergence AC, in prison
Diopters, to the stimulus to accommodation A in diopters AC:A ratio
• Typically bifocals given for treatment
Partially accommodative esotropia - Ans--A type of accommodative
esotropia that can be from significant uncorrected hyperopia which forces
the patient to exert excessive accommodation to focus on the retina, this
causes increased convergence.
Accommodative esotropia - Ans--- Can be from significant uncorrected
hyperopia which forces the patient to exert excessive accommodation to
focus images on the retina, those causes increased convergence
-Inward turning of eyes that develops between 6 months-7 years - most
often in children *2-3 years old*
- Related to *optical focusing (accommodation)*, frontal headaches when
reading
- Common in patients w/ *hyperopia (far-sightedness)* - in attempts to focus
the eyes - they converge their eyes as well to facilitate accommodation
reflex - *over-convergence* a/w extra accommodation required to
overcome hyperopic refractive error can precipitate loss of binocular control
and lead to development of esotropia
