New study aims to sharpen vision tests for brain injury patients
NCT ID NCT07282691
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is checking how well certain eye tests can measure vision problems caused by mild traumatic brain injury (mTBI). Researchers will test 150 people who had an mTBI within the last 1 to 6 months. The goal is to make these tests reliable for future studies on mTBI-related vision issues.
