About the Study
Every year, hundreds of thousands of people experience a mild traumatic brain injury (mTBI), often called a concussion. Most recover within 2 to 4 weeks, but about 30% continue to have symptoms that can last for weeks, months, or even years.
Research shows that vision problems are common after a concussion. These issues can make it harder to return to normal activities, such as work, school, sports, or daily tasks.
The most frequent vision problems after a concussion are:
- Difficulty focusing on near objects (convergence insufficiency) – affects about 30% to 42%
- Trouble adjusting focus between near and far (accommodative dysfunction) – affects about 22% to 47%
Because these vision problems are so common and can seriously affect daily life, we need better ways to assess and treat them.
Our Research Projects
Project 1:
We want to learn which areas of life are most affected by vision problems after mTBI. This will help us create a set of questions for a new survey that measures how these problems impact quality of life.

Project 2:
We are testing vision exams to see which ones work best for tracking progress in people with mTBI-related vision problems.
