PAVE System for Visual Field Loss
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called the PAVE System, which uses virtual reality to improve vision problems caused by stroke, brain injury, or brain surgery. The goal is to determine if this therapy can expand the visual field (the area a person can see) more effectively than a placebo. Participants will attend weekly therapy sessions, with regular checks on their vision progress. Ideal candidates for this trial are individuals experiencing long-term vision loss due to these brain conditions, diagnosed at least 6 months ago. As an unphased trial, this study offers a unique opportunity to explore innovative therapy for vision improvement.
Will I have to stop taking my current medications?
You may need to stop taking certain medications that could affect the therapy, like amphetamines or dopamine. It's best to discuss your current medications with the trial team to see if any changes are needed.
What prior data suggests that the PAVE System is safe for treating visual field loss?
Research has shown that the PAVE System, which uses a virtual reality headset to assist people with vision loss, has been generally well-received in past studies. This system aims to improve vision through visual exercises, and research has examined its effects on sight and quality of life.
No specific side effects have been reported, and the treatment is expected to be low-risk. Virtual reality technology is widely used and generally safe, making the PAVE System a promising option for those considering joining a trial to improve their vision. Potential participants should discuss any concerns with the trial team to ensure the treatment is suitable for them.12345Why are researchers excited about this trial?
Researchers are excited about the PAVE System for visual field loss because it introduces a novel approach using virtual reality technology. Unlike standard treatments like vision therapy exercises or magnification aids, the PAVE System uses a unique parallactic visual-field enhancement technique. This method aims to improve visual field awareness by providing a dynamic and immersive experience through a virtual reality headset. This innovative approach could offer a significant advantage in enhancing visual perception more effectively and engagingly.
What evidence suggests that the PAVE System is effective for visual field loss?
Research has shown that vision problems can improve by helping the brain reorganize itself, a process known as neuroplasticity. In this trial, participants in the test arm will use the PAVE System, which employs a virtual reality headset to provide visual exercises that might expand a person's field of vision. Previous studies have found that patients notice improvements in their vision after similar visual training methods. This suggests that the PAVE System could potentially help people with vision loss due to stroke or brain injury. While specific data on PAVE is limited, the concept is supported by research on the brain's ability to recover and enhance vision.12678
