Study of Visual Stimulation to Improve Peripheral Vision Loss in Adults with Hemianopsia After Stroke or Brain Injury

What this Trial Is About

Researchers are evaluating whether visual stimulation using images displayed on a computer screen can help improve peripheral vision loss in patients with hemianopsia caused by stroke or brain injury. This study aims to understand if stimulating the visual field can aid in recovering peripheral vision by examining changes after using visual programs. The research is important as many stroke survivors experience visual field deficits, impacting daily life and safety. Participants are assigned to one of two groups based on their birth year. One group will watch 15 minutes of online news three times a week for two months, serving as a control. The other group will view a 15-minute PowerPoint program containing moving objects and targets designed to stimulate the visual field with the goal of improving vision. After two months, the groups switch treatments for another two months, with participants able to opt out if they prefer to continue the PowerPoint program. During the study, participants undergo visual field testing using Humphrey automated perimetry at the start, after two months, and after four months. This test measures the visual field index to assess any changes in vision. Researchers also collect detailed patient information including stroke history, neurological diagnosis, and lifestyle factors. The study monitors visual recovery progress and compares the effects of the PowerPoint stimulation against the control viewing activity over time.
