ABO EXAM 2026 SPRING TEST QUESTIONS WITH ACCURATE SOLUTIONS- ALREADY
GRADED A+
The extra-ocular muscles are inserted into the sclera and serve to rotate the eye in all
possible directions. There are _______of these muscles.
Six
The fibrous tunic is comprised of the:
Sclera and cornea
Fusion occurs:
In the brain
The aqueous fluid is continually being manufactured by:
The ciliary body
The ability of the eye to bring objects of varying distances to focus on the retina is known
as:
Accommodation
When accommodation is at rest, rays of light from a distant source come to focus behind
the retina. This condition is known as:
,Hyperopia
Impulses are carried from the retina to the brain along the:
Optic nerve
That area of the retina capable of perceiving the greatest amount of detail is:
Fovea centralis
The average cornea has a refractive power of approximately:
43 diopters
The layer of the cornea which is highly regenerative is:
The epithelium
Night vision is chiefly a function of the:
Rods
A tendency of the visual axis to deviate inward while the eyes are in a position of rest is
known as:
Esophoria
,A "farsighted" eye is one that is:
Hyperopic
The term used to indicate "double vision" is:
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:
Presbyopia
When there is a loss of vision without any apparent disease of the eye it is known as:
Amblyopia
A refractive error in which the rays of light do not come to a single point of focus is called:
Astigmatism
The condition in which the crystalline lens of the eye gradually loses its transparency with
consequent loss of visual acuity is known as:
Cataract
, An ocular disease having as its primary characteristic a sustained increase in intraocular
pressure.
Glaucoma
The space between the front of the iris and the innermost portion of the cornea (the
endothelium), this space is filled with aqueous.
Anterior chamber
A tendency of one eye to deviate upward is:
Hyperphoria
The layer of the cornea which comprises ninety percent of its thickness is:
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:
Anisometropia
The refractive error which results in two points of focus falling behind the retina is:
Compound hyperopic astigmatism
