aadaptation of the eye for near vision by increasing the curvature of the lens
unequal pupil size
Arcus senilis
gray-white arc or circle around the limbus of the iris that is common with aging
Argyll Robertson pupil
pupil does not react to light: does constrict with accomodation
refractive error of vision due to differences in curvature in refractive surfaces of the eye (cornea and lens)
AV crossing
crossing paths of an artery and vein in te ocular fundus
Bitemporal hemianopsia
loss of both temporal visual fields
inflammation of the glands and eyelash follicles along the margin of the eyelids
poacity of the lens of the eye that develops slowly with aging and gradually obstructs vision
infection or retention cyst of a meibomian gland, showing as a beady nodule on the eyelid
Name the three concentric coats of the eyeball
sclera, choroid, retina
Name the functions of the ciliary body, the pupil and the iris
cliiary body- controls the thickness of the lens, produces the aqueus humor
iris- controls amount of light
PUPIL= center of the iris
Describe how an image formed on the retina compares with it's atual appearance in the outside world
upside down and reversed
To test for accomodation, the person focuses on a distant object, then shifts the gaze to a near object about 6 inches away. As near distanc, you would expect hte pupils to ______________ and the axes of the eyes to ______________________.
constrict, converge
decrease in power of accomodation that occurs with aging
The palpebral fissure is
a. the border between the cornea and sclera.
b. the open space between the eyelids.
c. the angle where the eyelids meet

d. VI and IV
c. V and VII
The retinal structures viewed through the opthalmoscope are
a. the optic disc, the retinal vessels, the general background and the macula
b. the cornea, the lens , the choroid, and the ciliary body.
c. the optic papilla, the sclera , the retina, and the iris
d. the pupil, the sclera, the ciliary body, and the macula.
a. the optic disc, the retinal vessels, the general background and the macula
The examiner records "positive consensual light reflex. this is:
a. the convergence of the axes of the eyeballs
b, the simultaneous constriction of the other pupil when one eye is exposed to bright light.
c. a reflex direction of the eye toward an object attracting a person's attention
D. the adaption of the eye for near vision
b, the simultaneous constriction of the other pupil when one eye is exposed to bright light.
Several changes occur in the eye with aging process. the thickening and yellowing of the lens is referred to as
a. presbyopia
b. floaters
c. macular degeneration
d. senile cataract
d. senile cataract

a. diplopia, scotoma
b. halos, epiphora
c.sudden onset of viision change
d. photophobia
c.sudden onset of vision change
Visual acuity is assessed with
a. snellen eye chart
b. an opthalmoscope.
c. The Hirschberg test
d. the confrontation test.
a. snellen eye chart
The cover test is used to assess for
a. nystagmus
b. peripheral vision
c. muscle weakness
d. extraocular muscle function
c. muscle weakness
the examiner is ready to use the opthalmoscope . the examiner would
a. remove his or her own glasses and approach the client's left eye with his or her left eye.
b. leave light on int hte examining room and remove glasses from the client
c. remove glasses and set the diopter setting at 0
d. use the smaller white light and instruct the client to focus on the opthalmoscope.
a. remove his or her own glasses and approach the client's left eye with his or her left eye.

lower eyelid rolling inward
protruding eyeballs
area of keenest vision at the center of the macula on the ocular pressure
