RightEye version 5.8 will be released on August 1, 2023 for all RightEye systems. This update includes our much anticipated, new Antisaccades Test.
New Antisaccades Test Features
The RightEye Antisaccade Test consists of:
- A battery of four (4) Testing Blocks, each containing fourteen (14) Antisaccade Trials. The entire Antisaccade Test will take 2-3 minutes to complete and includes a comprehensive output report. <link to Antisaccades page> <screen shot of testing screen with stimuli>
- New report includes the following metrics: Saccadic latency (ms), Saccadic amplitude (degrees), Target accuracy (millimeters), Antisaccade number (#), Prosaccade number (#), and Saccadic onset (ms). <link to Antisaccades page> <screen shot of results table(s)>
Antisaccades is a gross estimation of injury or dysfunction of the frontal lobe, by assessing the brain’s ability to inhibit the reflexive saccade (toward a visual stimuli) and “override” that movement leading to a saccade in the opposite (mirrored) direction.  Saccadic eye movement is primarily controlled by the frontal cortex.
To perform the anti-saccade trial, an individual is asked to fixate on a motionless target (the starting cross “+”) in the center of the screen. A stimulus (“X”) is then presented to one side of the target. The individual is asked to perform a saccadic movement in the direction away from the stimulus and then return back to briefly fixate on the starting cross and await the appearance of the next stimulus. For example, if a stimulus is presented to the left of the starting cross, the patient should rapidly move their eyes toward the right. Failure to inhibit a reflexive saccade is considered an error.
