Investigating how color vision is affected in veterans with mild traumatic brain injury
Official title: Individual Differences in Color Vision Assessed with Chromatic Textures
Funded at VA Loma Linda Healthcare System · NIH-11266146 · Data updated 2026-11-12
This study is looking at veterans with mild brain injuries who have trouble seeing colors, even when regular tests say their vision is fine, to create a new test that helps understand their visual problems better and find ways to help them.

Who could benefit from this research
✓Could help
Ideal candidates for this research are veterans who have experienced mild traumatic brain injury and report visual problems.
✕Less likely to help
Patients without a history of mild traumatic brain injury or those who do not report visual issues may not benefit from this research.
What this research studies
This research focuses on veterans who have experienced mild traumatic brain injury (mTBI) and often report visual issues despite normal clinical test results. The study aims to develop a new test for assessing color vision that considers both low-level (retinal) and high-level (cortical) visual processing changes. By examining how color vision is impacted, the research seeks to better understand the sensory deficits associated with mTBI. This could lead to improved diagnostic tools and interventions for affected individuals.
Why it matters
Potential benefit: If successful, this research could provide a more accurate assessment of visual function in veterans with mTBI, leading to better-targeted therapies and support.
How similar studies have gone: While the approach of assessing color vision in relation to mTBI is relatively novel, previous research has indicated that sensory processing can be affected by brain injuries, suggesting potential for success.
