CPOA Exam Questions and Answers
Graded A+
Miosis - Correct answer-Constriction of the pupil
Mydriasis (of pupil) - Correct answer-dilation of the pupil
nystagmus - Correct answer-is a vision condition in which the eyes make
repetitive, uncontrolled movements, often resulting in reduced vision
Synechia - Correct answer-an adhesion that binds the iris to an adjacent structure
such as the lens or cornea
Scotoma - Correct answer-Area or island of loss or impairment of vision
surrounded by a field of normal vision
Amblyopia - Correct answer-"Lazy eye"
Dullness or obscurity of sight for no apparent organic reason, therefore, not
correctable with glasses or surgery.Developmental problem in the brain.
strabismus - Correct answer-Eye misalignment caused by an imbalance in the
muscles holding the eyeball.

, Anisometropia - Correct answer-Condition caused by two eyes having significant
differences in refractive power, meaning one eye has much poorer vision than the
other
Aphakia - Correct answer-absence of the natural crystalline lens, usually after
cataract surgery or ectopia lentis
Ectopia Lentis - Correct answer-is a displacement or malposition of the eye's
crystalline lens from its normal location. A partial dislocation of a lens is termed
lens subluxation or subluxated lens; a complete dislocation of a lens is termed lens
luxation or luxated lens.
Asthenopia - Correct answer-eyestrain (asthenia = weak condition)
Binocular vision - Correct answer-The ability to merge visual images from both
eyes, thereby providing depth perception and a three dimensional view of the
world.
Canthus - Correct answer-angle where the upper and lower eyelids meet
Convergence - Correct answer-the simultaneous inward movement of both eyes
toward each other, usually in an effort to maintain single binocular vision at near
when viewing an object. This is the only eye movement that is not conjugate, but
instead adducts the eye.
