This test
has anecdotal proof-of-concept validation, but is strictly EXPERIMENTAL
and has not yet been
clinically or academically validated.
We are seeking assistance to have this test clinically
validated.

The eye has a preference for motion detection. Conditions of visual impairment such as
alcohol and marijuana intoxication, dementia, post-traumatic stress, or
concussion injuries MAY result in
a measurable reduction of cognition and motor skills. That associated reduction in motor and
cognition skills MIGHT be
quantitatively indicated by an impairment in motion detection as either a
delayed response or an increase incidence of errors in locating and
identifying the location and spinning direction of selected Dyop® rings. The Dyop® Visual Impairment Test requires a person
to identify the location and spinning direction of a Dyop® ring out of the
five Dyop® rings on the screen, four of which are static.
After the spin direction
selection, that spinning Dyop® ring becomes static and a different Dyop® ring
starts spinning until there have been 10 spinning ring trials with each of
the 5 Dyop® rings spinning twice. The program is intended for use on an
iPad or other 10 inch tablet.
The "normal"
non-invasive screening response has all 10 of the Dyop® ring spinning
sequences properly identified in approximately 14 to 20 seconds with no
errors, and should take 30 seconds or less if there is NO visual
impairment. Visual impairment (such as
from one glass of wine or 1 joint of marijuana) should slow the 10 sequence
test response to 30 or more seconds with 1 or more errors. Concussion
errors or other sources of dementia should have the same delayed and
increased errors response, as alcohol or marijuana. The more visual (and mental) impairment
there is, the longer it takes to complete the test with an increasing number
of errors.
We are seeking assistance to have this test clinically
validated. Letter from Governor Tom McCall Note: Dyop®
vision tests are for screening
purposes only and
are NOT a
substitute for an examination by a licensed vision care professional.
