CERTIFIED PARAOPTOMETRIC CPO 2026 REVIEW
QUESTIONS AND ANSWERS SURE A+
✔✔Pupil Dilation - ✔✔In order to get a more complete look at the back of the eye,
_______ is often done as part of a complete eye exam.
✔✔Nevus - ✔✔A mole; small and flat usually pigmented area; benign tumor made of
specific cells found in skin and eye tissue.
✔✔Fundus - ✔✔Interior posterior surface of the eyeball
✔✔Posterior Pole - ✔✔Refers to the retina between the optic nerve and macular area
✔✔Arcades - ✔✔Normal pattern of retinal blood vessels as they leave the optic nerve
head and arch around the macula.
✔✔Cotton Wool Spots - ✔✔Fluffy-looking white deposits resembling small tufts of
cotton within the retinal nerve fiber layer that represent small patches if retina that have
lost their blood supply from vessel obstruction.
✔✔Exudates - ✔✔Protein or fatty fluid that leaks from blood vessels into retinal tissue
, ✔✔Pachymetry - ✔✔An instrument that measures the thickness of the cornea. Useful in
monitoring the progression of certain disorders that cause the cornea to become
thickened resulting in a loss of vision. Also used to determine whether the cornea is
strong enough for refractive surgery procedures.
✔✔Optical Coherence Tomography (OCT) - ✔✔a laser-based, non-contact, non-
invasive imaging technique that is capable of obtaining high-resolution images of the
retina and its components.
✔✔Hyperopia - ✔✔Also known as farsightedness.
✔✔Extended Wear Contact Lenses - ✔✔Approved for wearing twenty-four hours,
including sleeping.
✔✔Presbyopia - ✔✔The loss of the ability to see clearly at a near distance, caused by
the crystalline lens losing its ability to change shape, or accommodate.
✔✔Base Curve Radius (BCR; BC) - ✔✔The primary curve on the posterior or backside
of the lens. Designed to approximate the shape of the cornea.
✔✔Overall Diameter (OAD) - ✔✔The size of the lens when measured from edge to
edge at the widest point.
✔✔Optical Zone Diameter (OZD; OZ) - ✔✔The cental area or zone that provides optical
correction for the patient's vision is called _______.
✔✔Peripheral Curves - ✔✔Additional curves on the back surface of the lens that
surround the optical zone to help tailor the contact lens fit to the individual patient.
✔✔Blood pressure assessment is performed with a: - ✔✔Sphygmomanometer and
stethoscope.
✔✔_______ is the term for the condition in which an image will focus on the back of the
retina when accommodation is relaxed. These patients will not require any corrective
prescription lenses. - ✔✔Emmetropia
✔✔What type of ametropia occurs when an image is focused in front of the retina and is
usually caused by the eye being too long? - ✔✔Myopia
✔✔The ability of the eyes to focus objects from distance to near is called: -
✔✔Accommodation
✔✔What type of lenses corrects hyperopia? - ✔✔Plus
