The extent of vision beyond the b) Vision beyond fixation is the visual field.
central fixation point is known as Binocular field is the visual field with both eyes.
the: A neurological field is a particular method of
a) binocular field testing. The pathway of light refers to the
b) visual field ocular structures through which light must pass
c) neurological field to reach the retina.
d) pathway of light
,The peripheral vision of a normal d) 95 degrees temporal, 75 degrees inferior, 60
person is: degrees nasal, and 60 degrees superior. The
a) 60 degrees temporal, 60 normal visual field is approximately 95 degrees
degrees inferior, 75 degrees nasal, temporal, 75 degrees inferior, 60 degrees
and 95 degrees superior nasal, and 60 degrees superior. You could pick
b) 75 degrees temporal, 60 this out even if the numbers were slightly
degrees inferior, 95 degrees different, if you remember that the temporal
nasal, and 60 degrees superior field is the widest and the nasal and superior
c) 95 degrees temporal, 60 fields are the narrowest.
degrees inferior, 75 degrees nasal,
and 60 degrees superior
d) 95 degrees temporal, 75
degrees inferior, 60 degrees
nasal, and 60 degrees superior
The configuration of the normal b) The brow and nose. The superior and nasal
visual field is delimited (ie: having fields are limited by the anatomical boundaries
fixed boundaries or limits) by: of the brow and nose. (The superior field also
a) the ear and nasal bridge is limited by the lids, which are not mentioned
b) the brow and nose in this question.)
c) the location of the fovea
d) the size of the optic nerve
The key to performing any type of a) Maintain fixation. Without proper fixation,
peripheral vision exam is to have any test of peripheral vision is invalidated.
the patient: Generally, the eyes are checked separately.
a) maintain fixation
b) look at the moving target
c) gaze into all four quadrants
d) use both eyes
,An object on the patient's right c) Temporal retina OS and nasal retina OD. An
will be perceived by the patient's: object on the patient's right will stimulate the
a) temporal retina OU temporal retina of the left eye and the nasal
b) nasal retina OU retina of the right eye. The foveae (plural of
c) temporal retina OS and nasal fovea) are used during central fixation, not for
retina OD peripheral vision.
d) foveae OU
The anatomic pattern of the nerve c) that correspond to the location of the nerve
fibers produces visual field fibers. Because the nerve fibers fan out in a
defects: specific anatomic pattern, visual field defects
a) that are total blind spots occurring in the nerve fibers also follow the
b) that correspond to the location same pattern. This makes diagnosis easier
of the rods and cones because the patterns are identifiable.
c) that correspond to the location
of the nerve fibers
d) that respond well to treatment
The "blind spot" as plotted on a c) The optic disc has no rods or cones to
visual field test corresponds to: receive light impulses. It is, therefore, an area of
a) the macula blindness commonly called the "blind spot."
b) the fovea The macula and fovea are at the center of the
c) the optic disc visual field and are normally the areas of
d) the angle highest sensitivity. The angle refers to the
internal point where the cornea and iris meet.
On the visual field, the average d) 15 degrees temporal to fixation. The average
blind spot is located: blind spot is located 15 degrees temporal to
a) 25 degrees temporal to fixation fixation. (The optic disc is anatomically located
b) 5 degrees nasal to fixation in the nasal part of the retina, which picks up
c) 15 degrees nasal to fixation the temporal field.)
d) 15 degrees temporal to fixation
, Visual nerve fibers terminate at b) Occipital cortex. The visual nerve fibers
the: terminate into the occipital cortex of the brain.
a) brain stem (The eye-related fibers that terminate in the
b) occipital cortex brain stem, only 10% of all the fibers, are
c) thalamus concerned with pupillary action and are not
d) pituitary visual.)
Conversion of the visual field map b) The island of vision profile is a three-
into a three-dimensional dimensional representation of the visual field.
representation results in: An isopter is a boundary. Comparative analysis
a) isopters and threshold gray-tone analysis are
b) the island of vision profile automated perimetry programs.
c) a comparative analysis
d) threshold gray-tone analysis
The peak of the island of vision d) Fovea. The peak of the island represents the
profile corresponds to the: area of highest visual sensitivity, the fovea.
a) optic nerve
b) center of the crystalline lens
c) nerve fiber layer
d) fovea
The blind spot would be a) A bottomless hole. The blind spot is devoid
represented on the island of vision of light receptor cells and would be
profile as: represented by a bottomless hole. A peak is
a) a bottomless hole the point of highest sensitivity. A dip and a pit
b) a peak have a bottom, indicating that a stimulus could
c) a shallow dip be found to which that area would respond.
d) a deep pit
