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 rotation direction of selected Dyop® images. The Dyop® Visual Impairment Test requires a
person to identify the location and rotational direction of the rotating
Dyop® on the screen out of five Dyop® images, four of which are
static.
After
the rotation direction selection, that rotating Dyop® image becomes static and
a different Dyop® image starts rotating until there have been 10 rotating
image trials with each of the 5 Dyop® images rotating 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®
image rotation 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. The Dyop® computer tests are
in an Adobe Flash Graphic format and may be viewed using Google Chrome or Internet Explorer (with
ActiveX enabled) or Firefox or
Safari or other graphic viewers
such as Irfanview
with the Flash Graphic
plug-ins with the free Adobe Flash Graphic Viewer enabled. |
The Dyop® (Dynamic
