-Test patient *with correction,* if worn (and note this)
-Test each eye separately, then together (OD/OS/OU)

Have patient read the smallest line in which they can identify more than half the letters -
ANS-20 feet
14 inches

Record as a notation, e.g. 20/20
-__: distance from chart (feet)
-__: distance a normal eye can read the line
-eg; 20/40 means the patient can read at 20 feet what a normal eye can at 40 feet -
ANS-N

D

If a visual acuity of 20/20 is achieved, then a refractive error is present. If not, _______
must be considered. Any child with a visual acuity in either eye of 20/__ or worse at
*age three to five* years or 20/__ or worse at *six years or older,* *or a two-line
difference in acuity between the two eyes,* should be referred to an ophthalmologist for
further evaluation - ANS-Amblyopia

20/40

20/30

What if patient cannot see largest letter?

What if they cannot see the big E at 3 feet? - ANS-Walk the patient toward the chart
until they see the big E.
Record as 10/200 (the 20/200 letter at 10 ft)

If patient unable to see big E at 3 feet, try:

, -Count fingers
-Hand motion
-Light perception
->20/200: legal blindness

-Purpose is to screen for visual field defect
-A visual field is the entire area seen by an eye when it looks at a central point
-Visual fields normally limited by the brows above, the cheeks below, and the nose
medially
-A lack of ______ _______ at the optic disc produces an oval blind spot in the normal
field of each eye, 15 degrees temporal to the line of gaze. - ANS-Visual Fields by
Confrontation, Retinal Receptors

-Imagine the patients visual fields projected onto a glass bowl that encircles the front of
the patients head
-Ask them to look with both eyes into your eyes.
-While you return the patients gaze, place your hands about 2 feet apart, lateral to the
patients ears
-Instruct the patient to point to your fingers as soon as they are seen
-Then slowly move the wiggling fingers of both your hands along the imaginary bowl
and toward the line of gaze until the patient identifies them
-Usually a person sees both sets of fingers at the same time - ANS-Visual Fields by
Confrontation

-If you find a defect, try to establish its boundaries
-Test one eye at a time several times and try to define the border of the defect
-Review different patterns of visual field defects (Table 6-4, pg. 212). Give three
examples: - ANS--Homonymous hemianopsia
-Bitemporal hemianopsia
-Quadratic defects

*A lesion at the Optic chiasm* may involve only fibers crossing over to the opposite
side. Since these fibers originate in the nasal half of each retina, visual loss involves the
temporal half of each field. - ANS-Bitemporal Hemianopsia

*A lesion of the optic tract* interrupts fibers originating on the same side of both eyes.
Visual loss in the eyes is therefore similar (homonymous) and involves half of each field
(hemianopsia). - ANS-Homonymous Hemianopsia (Right Optic tract)
