_____ is a circular, lymphatic-like vessel in the eye; it collects
aqueous humor from the anterior chamber and delivers it into
the episcleral blood vessels.
A. The ciliary body
B. Schlemm's canal
C. The trabecular meshwork
D. The ora serrata - ANSWER -B. Schlemm's canal
* An endothelium-lined tube, resembling that of a lymphatic
vessel
* On the inside of the canal, nearest to the aqueous humor, it is
covered and held open by the trabecular meshwork
* Schlemm's canal collects aqueous humor from the anterior
chamber
_____ is a condition in which there is apposition of the iris to
the lens or anterior vitreous, preventing aqueous from flowing
from the posterior to the anterior chamber. A. Exophthalmos
B. Graves Disease
C. Iris bombe
D. Glaucoma - ANSWER -C. Iris bombe
,* The pressure in the posterior chamber rises, resulting in
anterior bowing of the peripheral iris and obstruction of the
trabecular meshwork * This may result in acute attack of angle
closure glaucoma
What is an RAPD? - ANSWER -Rapid Afferent
Pupillary Defect
* When pupils react
asymmetrically to light
* Can mean disease of the retina or
optic nerve
A scotoma is
defined as:
A. Any type of visual
field loss
B. "Wavy" lines in the
visual field
C. Always being
deep
D. Found in the periphery only - ANSWER -A. Any type of
visual field loss
Lagophthalmos is defined as:
A. A margin-to-lid reflex distance of greater than 15mm
B. A common finding in patients with Graves disease
C. A delay in the closure of the upper eyelids in downward gaze
,D. Incomplete lid closure - ANSWER -D. Incomplete lid closure *
The main cause of lagophthalmos is facial nerve paralysis
(paralytic lagophthalmos)
* Can also occur after trauma or surgery (cicatricial
lagophthalmos) or during sleep (nocturnal lagophthalmos).
Changing the base curve of a contact lens changes the fitting
characteristics of that lens due to a change in sagittal depth.
Increasing the base curve radius of a contact lens while
maintaining the same diameter will cause the lens to fit:
A. Steeper and tighter
B. Flatter and looser
C. Higher and tighter
D. Lower and looser - ANSWER -B. Flatter and looser
Retinoblastoma - ANSWER -Tumor arising from a
developing retinal cell (a
congenital, malignant
tumor)
The instrument most commonly used to measure IOP by
flattening the cornea
is:
A. Schiotz
tonometer
B. Stein tension
tonometer
, C. Helmholtz applanation
tonometer
D. Goldmann applanation tonometer - ANSWER -D. Goldmann
applanation tonometer
* The Schiotz tonometer is not used commonly due to the
instrument not being capable of reliably detecting small
differences in pressures that correspond to the changes
observed with aging.
Retroillumination detects
A. Opacities or defects in the iris
B. Irregularities of the eyelids or eyelashes
C. The palpebral conjunctiva or sclera
D. Adverse corneal effects from CLS - ANSWER -A. Opacities or
defects in the iris
An eye with keratoconjunctivitis sicca (KCS) must be treated
with preservative free lubricating drops because:
A. The conjunctiva is discolored by the preservatives
B. Long term use is required and preservative free drops are
less expensive
C. Preservatives are toxic to the exposed or damaged corneal
cells
D. None of the above - ANSWER -C. Preservatives are toxic to
the exposed or damaged corneal cells
For A-Scans, the velocity of sound through the vitreous is
considered to be the same as through the: A. Cornea
B. Aqueous humor
C. Crystalline lens
