Home-based Vision Rehabilitation for Visual Field Loss
This study, called BRIGHT, is looking at how well home-based vision training can improve vision for people who have lost part of their visual field due to brain damage like a stroke or brain injury. Researchers are testing two types of training: "High-level perceptual learning-based training" and "Low-level perceptual learning-based training." These involve repeated computer tasks to help your brain process what you see. The study wants to see if these trainings improve your ability to tell the difference between visual things. You could be eligible if you are at least 18 years old, have visual field loss from brain damage that happened at least three months ago (or a stable brain tumor within the last year), and can safely have an MRI. The study aims to enroll 100 participants.
- Study design
- This study uses a crossover design, meaning participants will likely try both types of training. It involves visual testing, brain imaging, and home-based training.
- What's involved
- You would participate in computerized visual discrimination tasks at home. Your visual performance will be measured at Week 2-4 or Week 7-9 of the study.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your visual performance will be measured at Week 2-4 or Week 7-9 of the study, depending on the order of interventions.

What this trial measures
- Change in high-level perceptual discrimination performanceWeek 2-4 or Week 7-9 of the study (depending on the order)
Change in performance on an online computerized high-level perceptual discrimination task. Participants complete a computerized high-level perceptual discrimination task during a 3-week training period (5 days per week). Task difficulty is adaptively adjusted using a 3-up/1-down staircase procedure to estimate perceptual discrimination thresholds corresponding to approximately 75% accuracy.
- Change in low-level perceptual discrimination performanceWeek 2-4 or Week 7-9 of the study (depending on the order)
Change in performance on an online computerized low-level perceptual discrimination task. Participants complete a computerized high-level perceptual discrimination task during a 3-week training period (5 days per week). Task difficulty is adaptively adjusted using a 3-up/1-down staircase procedure to estimate perceptual discrimination thresholds corresponding to approximately 75% accuracy.
