orderly sequence?
Do you have blurred vision? - ANS ✔✔What is an important question to ask a patient that
complains of a "red eye" ?
Asthenopia - ANS ✔✔The term used to refer to symptoms due to uncorrected refractive error is
conjunctivitis - ANS ✔✔Symptoms associated with a red, irritated, bloodshot eye are most likely
due to a(n)
Eye fatigue - ANS ✔✔Which of the following MOST qualifies as a chief complaint?
Keratoconus; irregular cone-shaped cornea - ANS ✔✔Which common familial ocular disorder
should you record during a patient's history?
sudden loss of vision - ANS ✔✔Which of the following symptoms requires prompt attention?
medications ang dosages that the patient is currently taking - ANS ✔✔After introduction to the
patient, one of the first items that should be obtained as part of history taking is
determines if it's monocular or binocular diplopia - ANS ✔✔When a patient complains of
diplopia, why is it important to ask if the second image goes away when closing one eye?
,medication and contactant allergies - ANS ✔✔In general, which types of allergies should be
discussed w/ the patient?
Thyroid disorder - ANS ✔✔Of the following conditions, which one is least likely to cause
transient loss of vision?
ethnicity - ANS ✔✔Which history taking category would not typically be pertinent when
interviewing a patient with a chief complaint of headaches?
a weak or paralyzed extraocular muscle - ANS ✔✔Binocular double vision is always caused by
induced prism in spectacle lens - ANS ✔✔An improperly measured interpupillary distance (PD)
may result in
left pupil constriction - ANS ✔✔Consensual light reflex in the right eye results in
miosis - ANS ✔✔The state of pupillary constriction is known as
afferent pupillary defect; pupils respond differently to light stimuli due to unilateral or unknown
cause of neurological disorder where pupil constriction is impaired - ANS ✔✔If the amount of
light information transmitted to the brain from one eye differs from that of the other eye, the
patient has an
anisocoria - ANS ✔✔When pupils are of unequal size it's called
swinging flashlight test - ANS ✔✔Which test compares the direct and consensual light
responses to the pupil?
, irritation - ANS ✔✔A disadvantage of a chemical-based contact lens care system is
proteins - ANS ✔✔Soft contact lenses are susceptible to deposits of
usually more comfortable - ANS ✔✔An important difference between soft & rigid lenses is that
soft lenses are
DK ; amount of oxygen permeability of the lens - ANS ✔✔The permeability of a contact lens is
denoted by which value?
keratometer ; measures curvature of anterior surface of cornea - ANS ✔✔The instrument that
measures the curvature of the central part of the cornea is the
lensmeter - ANS ✔✔The instrument that measure the power of spectacle lenses is the
wait a few minutes after it's turned off - ANS ✔✔When replacing the projector's lamp, it's
important to

periodically with a
cotton tip swab & glass cleaner - ANS ✔✔What 2 items are used to clean retinoscopy lens,
polarizing lens, red lens & Maddox rod lens?
gently wiping off all exposed phoropter parts w/ alcohol - ANS ✔✔Routine maintenance on a
phoropter shouldn't include
using a measured weight attached to the tonometer balancing arm at 0, 2, 6 - ANS
