(Chapter 1) What disease is associated with increased pressure
inside the eye? Correct Answers Glaucoma
(Chapter 1) What does an orthoptist do? Correct Answers
Evaluates Strabismus
(Chapter 1) What does the abbreviation IJCAHPO stand for?
Correct Answers International Joint Commission on Allied
Health Personnel in Ophthalmology
(Chapter 1) What eye care professional routinely fills
prescriptions for eyeglasses? Correct Answers Optician
(Chapter 1) What eye care professional would fit a patient with a
prosthetic eye? Correct Answers Ocularist
(Chapter 1) What instrument does an ophthalmologist use to
examine the retina and optic nerve? Correct Answers
Ophthalmoscope
(Chapter 1) What is the first IJCAHPO level of certification?
Correct Answers Certified Ophthalmic Assistant
(Chapter 1) What responsibility routinely falls to the ophthalmic
medical assistant? Correct Answers Performing certain
diagnostic tests
,(Chapter 10) B-scan ultrasonography can be used for what
purpose? Correct Answers To characterize intraocular
structures and abnormalities, such as tumors
(Chapter 10) B-scan ultrasonography is useful for evaluating
what condition? Correct Answers Media opacities
(Chapter 10) Compression of the cornea during A-scan
ultrasonography may result in what kind of measurement error
and intraocular lens outcome? Correct Answers Shorter than
actual axial length measurement, with a resulting myopic
postoperative refractive error
(Chapter 10) Fluorescein angiography is most valuable for
evaluating what condition? Correct Answers Abnormalities in
ocular blood vessels
(Chapter 10) How does an interferometer measure visual acuity
potential? Correct Answers Projects lines onto the macula
(Chapter 10) The ocular media includes what transparent
structures? Correct Answers Cornea, lens, vitreous
(Chapter 10) What can A-scan ultrasonography be used for?
Correct Answers Measuring the axial length of the globe
(Chapter 10) What device measures the effect of media opacity
on visual acuity and does not require a clearer zone within the
media for assessment? Correct Answers Interferometer
,(Chapter 10) What does corneal topography measure? Correct
Answers Curvature of the cornea
(Chapter 10) What does optical coherence tomography measure?
Correct Answers Ocular anatomy
(Chapter 10) What does pachymetry measure? Correct Answers
Thickness of the cornea
(Chapter 10) What is an acuity chart printed in faint gray rather
than in sharp black on white useful for measuring? Correct
Answers Contrast Sensitivity
(Chapter 10) What is the most common complication of
fluorescein angiography? Correct Answers Nausea
(Chapter 10) What statement applies to commonly used
applanation tonometers? Correct Answers An abnormally thick
cornea produces an artificially high intraocular pressure reading
(Chapter 10) What test is used to count endothelial cells of the
cornea? Correct Answers Specular microscopy/photography
(Chapter 10) When undergoing A-scan ultrasonography prior to
cataract surgery, the patient looks to the side and the axial length
measured is 0.30 mm shorter than the patient's apical cornea-to-
retina distance. How does this affect the intraocular lens (IOL)
calculation? Correct Answers The IOL calculation will be 1.00
D more than the patient needs
, (Chapter 10) Why should a fluorescein or indocyanine
angiogram only be performed when a physician and emergency
equipment are available? Correct Answers Risk of anaphylaxis
(Chapter 11) In this visual field chart of the right eye, the shaded
area on the left shows decreased visual sensitivity. What is this
shaded area known as? Correct Answers Scotoma
(Chapter 11) In this visual field report of both eyes, the result
depicted is most often due to what condition? Correct Answers
Lesion or tumor near the optic chiasm
(Chapter 11) The technique of placing a target of a given size in
the visual field and gradually increasing its brightness until the
patient sees it is the basis for what test? Correct Answers
Threshold perimetry
(Chapter 11) What condition can help ensure an accurate
perimetry result? Correct Answers Having an appropriate add
or near correction in place
(Chapter 11) What condition causes a visual field defect that
respects the horizontal meridian? Correct Answers Glaucoma
(Chapter 11) What field of vision is affected by a defect in the
inferior temporal retina? Correct Answers Superior Nasal
(Chapter 11) What is an advantage of automated threshold
perimetry? Correct Answers It is more sensitive than kinetic
perimetry in detecting shallow defects.
