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.
