RightEye Concussion Testing and Beyond …


RightEye

As we’ve introduced to you through this blog, our colleagues have become increasingly involved with the impact of concussion on visual function, and the opportunities for improvement through vision therapy.  For a number of years we’ve successfully used infrared sensing technology for recording saccadic eye movements while reading, and we’ve also been using the K-D test which has surfaced as a player in helping to decide when an athlete should be removed from play.  I’ve been intrigued by the possibility of using infrared sensing technology to record pursuit eye movements in a user-friendly way in a more natural setting than sensors in goggles.

When the RightEye company approached me, my eyes widened.  They have introduced their first module called Neuro Vision as related to concussion.  “Neuro Vision” should not be confused with a program that was introduced about 10 years ago as a therapy tool for amblyopia, ultimately repacked as Revitalvision.  This technology is entirely different, and thus far has targeted objective eye movement recording as follows.

Smooth Pursuit

Measures the % of total test time spent in smooth pursuit of target. Smooth Pursuit Eye Movements are voluntary behaviors that become active when a moving target appears in the visual field.

Smooth Pursuit On Target

Measures the % of test time spent on target.

Eye/Target Velocity Error (Degrees)

Measures the error in smooth pursuit of target at target velocity error. The effect of working recall memory load, which requires time-to-attention, on eye tracking.

Horizontal Synchronization

Measures horizontal synchronization of eye movements with the target’s horizontal motion.

Vertical Synchronization

Measures vertical synchronization of eye movements with the target’s vertical motion.

Predictive Smooth Pursuit

Measures eye movements that jump ahead of the target. An indication that there is a phase lead, meaning same velocity range but directionally ahead.

Latent Smooth Pursuit

Measures eye movements that lag behind. An indication that there is a phase lag, meaning same velocity range but directionally behind.

I see opportunities for this technology to inform clinical assessment and monitoring of patient progress for a wide variety of conditions, including strabismus, amblyopia, and visual components of attention deficit.  Plans are in the works for metrics related to dynamic visual acuity and a variety of other performance measures.  By way of full disclosure, I have no financial interest in the company nor any formal relationship as a consultant.  You can view a brief interview about this technology on the Bright Ideas segment of the CNBC video below.  It occurs at the 21:20 mark, and runs for just under 5 minutes.
