ABO exam PrepAccommodation - CORRECT ANSWER-Focusing of the eye in a near object
theough relaxation of the ciliary muscle and thickening of the lens.
Amblyopia - CORRECT ANSWER-The loss of vision without any apparent
disease of the eye.
Ametropia - CORRECT ANSWER-A refractive error in which the eye, when in a
state of rest, does not focus the image of an object upon the retina, includes
hyperopia, myopia, and astigmatism
Aniseikonia - CORRECT ANSWER-A condition in which the ocular image of an
object as seen by one eye differs so much in size or shape from that seen by the
other eye that the two images cannot be fused into a single impression
Anisometropia - CORRECT ANSWER-A condition in which the refractive error of
one eye significantly differs from that of the other; each eye must have the same
sign i.e. Both eyes are myopic or hyperopic
Antimetropia - CORRECT ANSWER-The refractive condition whereby the signs
in each eye are opposite; one eye is hyperopic while the other is myopic
Aphakia - CORRECT ANSWER-An absence of the crystalline Lens of the eye
Aqueous humor - CORRECT ANSWER-The clear watery fluid that fills the
anterior and posterior chambers within the front part of the eye
Astigmatism - CORRECT ANSWER-A refractive error that prevents the light rays
from coming to a single focus on the retina because of the different degrees of
refraction in the various meridians of the eye
Cataract - CORRECT ANSWER-A condition in which the crystalline lens of the
eye, or its capsule, or both become opaque with consequent loss of visual acuity
, Choroid - CORRECT ANSWER-The vascular intermediate coat that furnishes
nourishment to other parts of the eyeball
Ciliary body - CORRECT ANSWER-That portion of the vascular coat between
the iris and the choroid. It consists of ciliary processes and the ciliary muscle
Compound hyperopic astigmatism - CORRECT ANSWER-The refractive error
which results in two points of focus falling behind the retina
Compound myopic astigmatism - CORRECT ANSWER-The refractive error
which results in two points of focus falling in front of the retina
Cornea - CORRECT ANSWER-The clear transparent portion of the outer coat of
the eyeball forming the covering of the aqueous chamber
Crystalline lens - CORRECT ANSWER-A transparent colorless body suspended
in the front part of the eyeball, between the aqueous and the vitreous, the
function of which is to bring the rays of light to focus on the retina
Diplopia - CORRECT ANSWER-The seeing of one object as two
Emmetropia - CORRECT ANSWER-The refractive condition of the normal eye
when the eye is at rest, the image of distant objects is brought to a focus on the
retina
Fusion - CORRECT ANSWER-The power of coordination by which the images
received by the two eyes become a single image
Fovea - CORRECT ANSWER-A small depression in the retina at the back of the
eye; the part of the macula adapted for most acute vision
Glaucoma - CORRECT ANSWER-An ocular disease having as its primary
characteristic a sustained increase in intraocular pressure that the eye cannot
withstand without damage to its structure or impairment of its function
Hyperopia - CORRECT ANSWER-A refractive error in which, because the
eyeball is short or the refractive power of the lens is weak, the point of focus for
