3.Question:
A 60-year-old was concerned about a yellowish colored lesion above her right eyelid.
Findings revealed a slightly raised yellowish, well circumscribed plaque along the
nasal area of her right eyelid. This finding is most consistent with:
apinguecula.
achalazion.
episcleritis.
xanthelasma.
,Explanation:
Slightly raised, yellowish, well-circumscribed plaques appearing along the nasal area
of one or both eyelids are consistent with lipid disorders and called xanthelasma.

of the eyelid. Episcleritis is an ocular inflammation of the episcleral vessels.
4.Question:
Assessment of a patient's visual acuity resulted in 20/200 using the Snellen eye
chart. This means that:
at 200 feet the patient can read printed information that a person with normal vision
could read at 20 feet.
at 20 feet the patient can read printed information that a person with normal
vision could read at 200 feet.
the patient has normal visual acuity.
the patient may not be able to read so he should be tested with the picture or "E" eye
charts.
Explanation:
, Visual acuity that is corrected to 20/200 constitutes legal blindness. The larger the
number under 20, the worse the visual acuity. If this is a new finding, the patient
needs ophthalmologic evaluation.
5.Question:
Findings following assessment of a person's left eye gaze include impaired
movements when attempting to look upward, downward, or inward. This condition is
most consistent with:
a conjugate gaze.
left cranial nerve III (oculomotor) paralysis
cranial nerve IV (trochlear) paralysis.
cranial nerve VI (abducens) paralysis.
Explanation:
With a left cranial nerve III paralysis, upward, downward, or inward movements are
impaired. In conjugate or normal gaze, the normal movement of the two eyes
appears simultaneously in the same direction to bring something into view. With a
left cranial nerve VI paralysis, a person's gaze would include eyes conjugate when
looking to the right, esotropia (one or both eyes turn inward) appears in the left eye
when looking straight ahead, and esotropia is maximum in the left eye when looking
to the left. The left eye is unable to look down when turned inward in a left cranial
nerve IV paralysis.
