ClinConnect Summary

This clinical trial, called "Home-based Vision Therapy," is focused on helping U.S. Military Veterans who have experienced traumatic brain injuries (TBI) and are struggling with near vision problems. Many Veterans find it difficult to see things up close, which can lead to issues like double vision, trouble reading, and challenges with tasks that require good hand-eye coordination. The goal of this study is to explore new virtual-reality tools and training games that could help improve near vision diagnosis and provide rehabilitation that can be done at home. By restoring normal near vision, this therapy may significantly enhance Veterans' ability to succeed in school, work, and daily life.

To take part in this trial, participants need to be U.S. Military Veterans, live near Cleveland, OH, and have had a recent eye exam showing they can see well (20/25 vision or better). They also need to have a specific condition called convergence insufficiency, which affects how well their eyes work together when looking at things up close. Unfortunately, individuals with certain neurological conditions or prior eye issues may not be eligible. This trial is currently not recruiting participants yet, but it offers a promising opportunity for Veterans seeking to improve their vision and overall quality of life.
