Disparity Driven Vergence in Mild Traumatic Brain Injury (mTBI)
June 3, 2022 updated by: Michael E. Hoffer, University of Miami
Examining Disparity Driven Vergence as a Potential Diagnostic Test for Mild Traumatic Brain Injury (mTBI)
This study aims to determine the validity and safety of disparity driven vergence using a portable goggle system (I-PAS) using a pseudorandom ternary sequence of frequencies for testing.
