CORRECT
◉ The extra-ocular muscles are inserted into the sclera and serve to
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 aqueous fluid is continually being manufactured by: Answer:
The ciliary body
◉ 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: Answer:
Hyperopia
◉ Impulses are carried from the retina to the brain along the: Answer:
Optic nerve
,◉ 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
◉ Myopia means the eye
A. is nearsighted
B. has distance blur
C. requires a (-) minus lens
D. all of the above Answer: D. all of the above
◉ The Retina contains
A. lab tools
B. lens information
C. light receptors
D. understock of frames Answer: C. light receptors

A. distance objects
B. near objects
