ACCOMMODATION
|
Focusing of the eye on a near object through relaxation of the ciliary muscle and thickening of the lens.
|
|
AMBLYOPIA
|
The loss of vision without any apparent disease of the eye.
|
|
AMETROPIA
|
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
|
A condition in which the ocular image of an object as seen by one eye differs so much in size of shape from that seen by the other eye that the two images cannot be fused in to single impression.
|
|
ANISONMETROPIA
|
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 of hyeropic.
|
|
ANTIMETROPIA
|
The refractive condition whereby the signs in each eye are opposite; one eye hyperopic while the other myopic.
|
|
APHAKIA
|
An absence of the crystalline lens of the eye.
|
|
AQUEOUS HUMOR
|
The clear watery fluid that fills the anterior and posterior chambers with in the front part of the eye.
|
|
ASTIGMATISM
|
A refractive error that prevents the light rays from coming to a single focus on the retina because of different degrees of refraction in the various meridians of the eye.
