rotate the eye in all possible directions. There are _______of these
muscles. - ,,,answer,,,,..Six
The fibrous tunic is comprised of the: - ,,,answer,,,,..Sclera and cornea
Fusion occurs: - ,,,answer,,,,..In the brain

The ability of the eye to bring objects of varying distances to focus
on the retina is known as: - ,,,answer,,,,..Accommodation
When accommodation is at rest, rays of light from a distant source
come to focus behind the retina. This condition is known as: -

That area of the retina capable of perceiving the greatest amount of
detail is: - ,,,answer,,,,..Fovea centralis
The average cornea has a refractive power of approximately: -
,,,answer,,,,..43 diopters
,The layer of the cornea which is highly regenerative is: -
,,,answer,,,,..The epithelium
Night vision is chiefly a function of the: - ,,,answer,,,,..Rods
A tendency of the visual axis to deviate inward while the eyes are in
a position of rest is known as: - ,,,answer,,,,..Esophoria
A "farsighted" eye is one that is: - ,,,answer,,,,..Hyperopic
The term used to indicate "double vision" is: - ,,,answer,,,,..Diplopia
The condition in which the ability to accommodate for near vision
becomes inadequate because of loss of elasticity of the crystalline
lens is called: - ,,,answer,,,,..Presbyopia
When there is a loss of vision without any apparent disease of the
eye it is known as: - ,,,answer,,,,..Amblyopia
A refractive error in which the rays of light do not come to a single
point of focus is called: - ,,,answer,,,,..Astigmatism
The condition in which the crystalline lens of the eye gradually loses
its transparency with consequent loss of visual acuity is known as: -
,,,answer,,,,..Cataract
An ocular disease having as its primary characteristic a sustained
increase in intraocular pressure. - ,,,answer,,,,..Glaucoma
The space between the front of the iris and the innermost portion of
the cornea (the endothelium), this space is filled with aqueous. -
,,,answer,,,,..Anterior chamber
,A tendency of one eye to deviate upward is: -
,,,answer,,,,..Hyperphoria
The layer of the cornea which comprises ninety percent of its
thickness is: - ,,,answer,,,,..The stroma
A condition in which the refractive error of one eye significantly
differs from that of the other and where both eyes have the same
sign (i.e. both eyes are myopic or hyperopic) is known as: -
,,,answer,,,,..Anisometropia
The refractive error which results in two points of focus falling
behind the retina is: - ,,,answer,,,,..Compound hyperopic astigmatism
The refractive condition caused by a damaged cornea so that rays of
light come to many focal points on the retina is known as: -
,,,answer,,,,..Irregular astigmatism
The index of refraction of the crystalline lens is: - ,,,answer,,,,..1.42
The index of refraction of the cornea is: - ,,,answer,,,,..1.37
