Study Summary
This trial will test a new virtual reality headset that shows 3D images of oncoming pedestrians to help people with visual field loss improve their mobility.
Who is the study for?
This trial is for people with visual field loss, such as hemianopia or tunnel vision. Participants must have binocular vision within normal limits, at least partial peripheral vision, and a visual acuity of no worse than 20/100 in the weaker eye. They should be over 14 years old, healthy enough for sessions up to 3 hours, understand English, consent voluntarily, and move independently.Check my eligibility
What is being tested?
The study is testing a new virtual reality (VR) system designed to help individuals with visual field loss detect obstacles while walking. It involves wearing a VR headset that simulates real-world environments and oncoming pedestrians in three dimensions.See study design
What are the potential side effects?
While not explicitly stated, potential side effects may include discomfort from wearing the VR headset, motion sickness due to virtual reality exposure, eye strain from prolonged use of the device or temporary disorientation after using the VR system.

Other Research
The most common treatments for Homonymous Hemianopia include visual field expansion techniques, such as the use of prisms and virtual reality (VR) head-mounted displays. Prisms work by shifting images from the non-seeing side to the seeing side, thereby expanding the visual field.
VR head-mounted displays create a simulated 3D environment that helps patients practice and improve their visual-motor coordination and hazard detection in a controlled setting. These mechanisms are crucial for Homonymous Hemianopia patients as they enhance their ability to navigate their environment safely and independently, improving their overall quality of life.
