JCAHPO Certified Ophthalmic Assisting Exam
Questions with 100% Correct Answers
abduction Correct Answer: The movement of the eye
outward toward the temple.
aberrometry Correct Answer: The measurement of
optical aberrations of the visual system using a device
called a wavefront analyzer or an aberrometer.
abrasion Correct Answer: A scratch.
abscess Correct Answer: A localized collection of pus
surrounded by inflamed tissue.
absolute scotoma Correct Answer: A severe visual field
defect in which the largest and brightest stimulus cannot
be seen; blindness at that specific location.
accommodation Correct Answer: The change in the
curvature of the crystalline lens that helps to focus
images of objects close to the eye.
acidic burns Correct Answer: A chemical injury to tissue,
caused by an agent of low pH.
,acquired immunodeficiency syndrome (AIDS) Correct
Answer: An infection with human immunodeficiency
virus (HIV) that causes a compromised immune system.
acute Correct Answer: Refers to a condition that flares
up suddenly and persists for only a short time.
add Correct Answer: The lower portion of the multifocal
lens (usually the lower part) that provides correction for
near vision. Also called segment or near add.
adduction Correct Answer: The movement of the eye
inward toward the nose.
adenovirus Correct Answer: A family of viruses involved
primarily in respiratory infections; can cause highly
contagious forms of conjunctivitis.
adnexa Correct Answer: The tissues and structures
surrounding the eye; includes the orbit, extraocular
muscles, eyelids, and lacrimal apparatus.
afferent pupillary defect (APD) Correct Answer: A pupil
with normal iris function that fails to constrict normally
with direct light stimulation but reacts strongly
,consensually, or when the fellow eye is stimulated.
Usually secondary to optic nerve disease.
"against motion" Correct Answer: The retinoscopic reflex
movement that is in the opposite direction from the
movement of the streak of light from the retinoscope;
typical of the myopic eye.
age-related macular degeneration Correct Answer: A
disease in which sensory cells of the macula
degenerate, resulting in a loss of central vision; usually
affects older people.
alkali burn Correct Answer: A chemical injury to tissue,
caused by an agent of high pH.
allergic reaction Correct Answer: A condition in which
the body produces antibodies to foreign materials such
as food, plant pollens, or medications.
alternate cover test Correct Answer: A test performed
by placing an occluder over one eye and then moving
it slowly over to the other eye to detect a tendency for
the eyes to deviate while under the occluder (such an
, ocular misalignment is known as a phoria). Also called
cross-cover test.
altitudinal scotoma Correct Answer: The joining and
enlargement of a nasal step visual field defect and an
arcuate scotoma to cause loss of the entire upper or
lower visual field.
amblyopia Correct Answer: Decreased vision present
without apparent abnormalities in the ocular anatomy
and uncorrectable by spectacles or contact lenses;
results from visual deprivation in early childhood.
ametropia Correct Answer: The refractive state of an
eye that is unable to focus correctly due to a refractive
error.
Amsler grid test Correct Answer: A test for determining
the presence and location of defects in the central
portion of the visual field.
anatomy Correct Answer: The structure of an organism.
