**Trial Summary: Screening Instruments for Measuring Visual Symptoms in Victims of Concussion**
This clinical trial is focused on understanding vision problems that can occur after a mild traumatic brain injury (mTBI), commonly known as a concussion. Many people with mTBI experience visual difficulties, but these issues often go unnoticed for a long time. The researchers aim to develop tools that can help identify these visual problems more effectively. They will create a questionnaire for patients to express their visual complaints and use eye-tracking technology to measure how well their eyes are functioning. By comparing patients' reports with actual eye measurements, the study hopes to improve the diagnosis and treatment of visual symptoms related to mTBI.
To participate in this study, individuals must be between the ages of 18 and 67 and have been diagnosed with mTBI by a doctor. They should have ongoing visual symptoms for at least two months but not more than 24 months after their injury. Participants will be asked to fill out questionnaires about their vision, undergo eye tests, and participate in eye-tracking assessments. Those who have certain serious medical conditions or other specific eye problems will not be eligible. This research is crucial for finding better ways to support individuals recovering from concussion and ensuring they receive the appropriate care for their visual challenges.
