1. A client presents to the clinic complaining, “I have something in my eye.” When
questioned, the client admits to a scratching and burning sensation and light
sensitivity. The health care provider suspects the client has developed:
A) Conjunctivitis
B) Retinal detachment
C) Acute glaucoma
D) Corneal edema
Ans: A
Feedback:
Conjunctivitis causes bilateral tearing, itching, burning, foreign body sensation, and
morning eyelash crusting and eye redness. The primary symptom of retinal detachment
is painless changes in vision. Commonly, flashing lights or sparks, followed by small
floaters or spots in the field of vision, are early symptoms. Attacks of glaucoma
(increased intraocular pressure) are manifested by ocular pain, excruciating headache,
blurred or iridescent vision, and corneal edema with hazy cornea, dilated (mydriasis),
and fixed pupil; with repeated or prolonged attacks, the eye becomes reddened. With
corneal edema, the cornea appears dull, uneven, and hazy; visual acuity decreases; and
iridescent vision (i.e., rainbows around lights) occurs.

2. Which of the following people are at high risk for developing nonulcerative
inflammation of the cornea? Select all that apply.
A) A welder with inadequate eye protection
B) A contact lens wearer who is noncompliant with cleaning and sterilizing the lens
C) A female who uses a tanning bed four to five times/week
D) A person who touched the fever blister and then rubbed the eye
E) A ski patrol who works 12 hours/day in bright, sunny mountain
tops Ans: A, C, E
Feedback:
In nonulcerative keratitis, all the layers of the epithelium may be affected, but the
epithelium remains intact. There are a number of causes of epithelial keratitis, including
epidemic keratoconjunctivitis caused by adenoviruses 8 and 19 and ultraviolet (UV)
light exposure keratitis. Most cases of UV keratitis occur in welders with inadequate
eye protection, but may also occur with tanning booth and other UV lamp exposure, and
from sun reflecting off snow. Most cases of herpes keratitis are caused by HSV type 1
(labial [lip] herpes) and is ulcerative in nature. Acanthamoeba keratitis is a rare but
sight-threatening complication that typically occurs in people who wear soft contact
lens, particularly overnight or without proper disinfection.
3. During accommodation, pupillary dilation partially compensates for the reduced size of
the retinal image by:

answers
A) Thickening the lens
B) Contracting the ciliary muscle
C) Increasing light entering the pupil
D) Narrowing the palpebral opening
Ans: C
Feedback:
Accommodation is the process whereby a clear image is maintained as gaze is shifted
from far to near objects. During accommodation, pupillary dilation partially
compensates for the reduced size of the retinal image by increasing the light entering the
pupil. Accommodation requires convergence of the eyes, pupillary constriction, and
thickening of the lens through contraction of the ciliary muscle, which is controlled
mainly by the parasympathetic fibers of the oculomotor cranial nerve (CN III). A third
component of accommodation involves reflex narrowing of the palpebral opening
during near vision and widening during far vision.
4. A client develops fever, headache, and burning/itching in the periorbital area. After a
few days, a vesicular rash appears around the eyelid margins. The health care
provider will likely prescribe:
A) Topical antimicrobial for infection caused by overuse of contact lens
