Home-Based Vision Training Using Brain Imaging to Improve Visual Field Loss After Brain Injury or Stroke

What this Trial Is About

Researchers are evaluating home-based vision training guided by brain imaging to improve visual field loss in individuals with focal brain damage caused by conditions such as stroke, traumatic brain injury, or brain tumors. This study uses a prospective, randomized crossover design combining visual behavioral testing, neuroimaging, and home-based interventions to explore brain pathways supporting visual plasticity and compare different types of visual training. Participants will undertake two types of at-home online perceptual learning-based training one using high-level visual stimuli targeting higher-order visual processing, and the other using low-level visual stimuli targeting basic visual processing. Each training phase lasts three weeks, with participants completing both training types in a randomized order to assess their effects on visual performance. During the study, participants will complete behavioral visual tests and brain imaging to measure changes in visual discrimination performance after each training phase. The primary outcomes focus on improvements in both high-level and low-level perceptual discrimination between weeks 2-4 and 7-9, depending on the training sequence. The total participation involves these two training periods with assessments to monitor visual function and brain activity changes over time.
