Peripheral Test
This is a test of peripheral vision on the horizontal plane. The lights flash at 85, 70, and 55
degrees temporally and approximately 45 degrees nasally, so a possible total of 1
3
0 degrees
arc can be attained. (Highest temporal reading plus nasal reading).
Caution should be taken because the temples of eyeglass frames could interfere with this
test. The test should be taken with eyeglasses on and again with the glasses off to determine
if the frame interferes with peripheral vision.
To Administer The Test:
1.
FAR Switch ON
2.
RIGHT Eye switch ON
3.
LEFT Eye switch OFF
4.
Dial #
1
at Yellow Indicator
Subject should look straight ahead, through the FAR lens system, with his/her forehead against
the headrest activator. Ask the subject to look at slide #1. Then ask the test subject to point his
finger in the direction he sees the light. The test administrator will then press one of the four
switches, nasal, 55, 70 or 85 degrees on the control panel. The switches can be pressed in any
order and should be held down for two or three seconds. Repeat the test with the left eye by
turning the RIGHT illuminated switch off and turning the Left illuminated switch on.
NOTE: This test can be administered to a one-eyed person. In this case, the nasal test
becomes very important because it will determine if there is peripheral vision on the blind side.
