MSP Final Exam with correct answersoccurs when the eyesight is deprived by limited illumination and vision range, or the eye is
modified with lenses or deprived of clear form vision - correct answer -Form deprivation myopia
axial elongation --> myopia - correct answer -Depriving the eye from vision
Chronic image degradation can cause myopia
Myopia can be sectorial—deprive any light stimulus on one part of the retina - correct answer -Depriving
the eye from vision
essential for normal refractive development - correct answer -clear retinal image
similar to those associated w/ juvenile-onset myopia - correct answer -ocular changes in form
deprivation myopia
To compensate, the eye must become more hyperopic - correct answer -Optically imposed myopia
To compensate, the eye must become more myopic - correct answer -Optically imposed hyperopia
can control the development of RE by controlling the focus or environment - correct answer -Lens
compensation
does not slow the growth of the eyes - correct answer -Under-correcting a child
Investigated the effects of brief daily interruptions of lens wear on the ocular compensation for
negative lenses in infant monkeys - correct answer -Hyperopic defocus vs unrestricted vision
Monkeys wore -3D lenses binocularly—some worn continuously; others had lenses removed for
, four 15-minute periods each day (1 hour total) - correct answer -Hyperopic defocus vs unrestricted
vision
group of animals who wore the -3D lenses continuously exhibited axial myopia - correct answer -
Hyperopic defocus vs unrestricted vision
brief, daily periods of viewing through pl lenses - correct answer -eliminated myopic changes
can prevent the axial myopia - correct answer -Brief periods of unrestricted vision
integrating properties of the
emmetropization process normally reduce the likelihood that transient periods of hyperopic defocus will
cause myopia - correct answer -Conclusion:
Visual signals that increase axial growth and those that reduce axial growth - correct answer -not
weighted equally
-acuity is highest at the fovea and decreases rapidly with eccentricity
-assumed that central vision dominates refractive development - correct answer -Not true
Myopes typically exhibit relative
hyperopia - correct answer -in the periphery
hyperopes show relative myopia - correct answer -in the periphery
signals from the periphery - correct answer -ocular growth
no apparent effect on emmetropization - correct answer -Foveal ablations
not essential for normal refractive development - correct answer -Visual signals from the fovea
