Optec 5000PG 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 170 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:
FAR Switch ON
RIGHT Eye switch ON
LEFT Eye switch OFF
Dial #6 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 the slide. Then ask the test subject to point a finger in the direction of the light. The test
administrator will then press one of the four switches, one yellow, and three blue, 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 occluder OFF and the LEFT occluder 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.
