Certified Ophthalmic Assistant (COA) – JCAHPO Study Guide Practice Questions and
Comprehensive Exam Preparation Material
When reading add power on the lensometer take the difference between the triple line target
distance reading and the _____.
A. Single line distance reading
B. Triple line bifocal reading
C. Single line bifocal reading
D. Zero point - ✔✔B. Triple line bifocal reading
What is a yellow top on eye drops for?
A. Carbonic anhydrase inhibitors
B. Prostaglandin analogues
C. Beta-blockers
D. Cycloplegics - ✔✔C. Beta-blockers
* Can also be light blue!
* Used to treat glaucoma; it helps to decrease the production of aqueous humor and reduce
IOP
* Examples:
- Timolol
- Levobunolol
- Betaxolol (light blue top)
The purpose of keratometry is to measure: - ✔✔The curvature of the anterior corneal surface
An eye alignment deviation that is not present unless fusion is disrupted is called a:
A. Phoria
,B. Tropia
C. Hyper deviation
D. Eso deviation - ✔✔A. Phoria
* Tropia and Phorias are terms to describe when the eyes are not in alignment with each other
* A tropia is always present, while phorias are there "some of the time," such as when the
patient is tired or when fusion is broken (you cover an eye and it starts to drift).
The endpoint of the Maddox Rod test occurs when:
A. The red dot is superimposed on the light
B. The red line goes through the light
C. The red line disappears
D. The red line is above the light - ✔✔B. The red line goes through the light
A condition in which blood has settled in the bottom half of the anterior chamber of the eye is
called a:
A. Subconjunctival hemorrhage
B. Pink eye
C. Hyphema
D. Glaucoma - ✔✔C. Hyphema
* A subconjunctival hemorrhage will only involve the white of the eye, not the center, and will
typically have no pain associated with it
* A hyphema will only affect the center of the eye, behind the cornea, and will usually have pain
and additional symptoms associated with it
An outward deviation of the eye(s) is a(n) ____ and an inward deviation of the eye(s) is called
a(n) ______.
A. Esodeviation / Exodeviation
B. Esophoria / Exophoria
,C. Exodeviation / Esodeviation
D. Exophoria / Esophoria - ✔✔C. Exodeviation / Esodeviation
* Esotropia means that one eye is deviated inward and is often called crossed eyes
* Exotropia is when one or both eyes look outward, often called wall-eyed
* A tropia is always present, while phorias are there "some of the time".
Kinetic perimetry means that the light stimulus is:
A. Moving from an area of non-seeing to an area of presumed seeing
B. A stimulus that is presented to the patient but not moved
C. A situation in which visual fields are performed without either eye being occluded
D. The stimulus is jiggled slightly so the patient can see it - ✔✔A. Moving from an area of non-
seeing to an area of presumed seeing
* The two most commonly used types of perimetry are Goldmann kinetic perimetry and
threshold static automated perimetry
What is the name of the condition where a fibrovascular growth forms on the conjunctiva to a
portion of the cornea?
A. Pterygium
B. Pinguecula
C. Exteration
D. Entropion - ✔✔A. Pterygium
* A pinguecula is characterized by a yellowish raised growth on the conjunctiva typically at the
nasal or temporal conjunctiva near the edge of cornea
* Pterygium is the triangular shape of vascularized conjunctival tissue on the cornea and it
invades the cornea (known as fibrovascular invasion of the cornea)
Forward displacement of the eye in it's bony socket causing the eye to bulge forward is termed:
A. Exophthalmos
, B. Neoplasia
C. Buphthalmos
D. Exophasia - ✔✔A. Exophthalmos
* Exophthalmos is a normal-sized globe that is being pushed forward by a space-occupying
lesion in the orbit.
* Buphthalmos is a normally-positioned globe that is enlarged due to elevated intraocular
pressure, i.e., glaucoma
_____ is the distance from the front surface of the cornea to the back side of a lens that is
mounted in a frame and being worn by the patient.
A. Back vertex
B. Lens vertex
C. Vertex distance
D. Front vertex - ✔✔C. Vertex distance
A non-contact lens to examine the macula is:
A. Goniolens
B. Hruby lens
C. Koeppe lens
D. Maddox lens - ✔✔B. Hruby lens
* It is held immediately in front of the cornea and forms a virtual, erect, and minified image of
the retina
* A Koeppe lens allows examination of both the angle and the posterior pole
Which blood vessels have valves?
A. Veins
B. Arteries
