Eye Recovery Automation for Post Injury Dysfunction (iRAPID)
Trial Parameters
Brief Summary
This study will test a portable virtual reality (VR) system with integrated eye tracking called Virtual Eye Rotation Vision Exercises (VERVE). The proposed VERVE platform will deliver vergence therapy in an automated manner. This research will involve 30 non-traumatic brain injury (TBI) binocularly normal (BNC) Veterans and 50 post-traumatic convergence insufficiency (PTCI) Veterans who will undergo Active and Sham therapy (equally divided groups) to determine the effectiveness of VERVE vergence therapy.
