AV-Stimulation in VR for Vision Impairment
Toronto, Ontario
The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments.
The main questions it aims to answer are:
1. Can the 6-week IVR stimulation program help improve driving performance?
2. Will participants experience improvement in visual detection and perception after training?
Study Design Summary:
* Participants will be randomized into a waitlist group or intervention-first group
* The VR-based intervention will consist of training every 2 days for six weeks
* Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7)
* Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint
* Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study
Researchers will analyze data for changes from baseline in outcome measures.

Why Other Patients Applied
I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me.

I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials.
WR
Obesity PatientAge: 58
I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me.

Virtual Reality Visual Field Testing for Eye Diseases
Durham, North Carolina
The purpose of this study is to test a new way of measuring the peripheral vision (called a visual field test) using a device which can be worn as goggles rather than being a large instrument the patient must sit at. This new visual field test (called VisuALL) is an FDA-approved virtual reality system which has been used in adults and children. This study will compare the performance of the VisuALL to the standard testing for peripheral vision, which is called the Humphrey Visual Field (HVF) test.
The study will recruit both healthy children, as well children and young adults who have eye conditions which require visual field testing as part of their standard care. The test will be performed on a day when the child or young adult already has a scheduled eye appointment as standard care. The test does not touch the eyes or require any eye drops to be given, and there is no known risk associated with the test itself. There may be a risk of loss of confidentiality. Participating in this study will require approximately 30 minutes, has no extra cost associated with it, and will be compensated by a parking pass for the day of the visit. There are no direct benefits for participants.
Selected participants will be also be given training and then loaned a home VisuALL system to allow home visual field testing. If your child is selected, additional information would be provided.

Virtual Reality Navigation for Partial Vision Loss
Rochester, New York
The purpose of this research is to better understand the impact of cortically-induced blindness (CB) and the compensatory strategies subjects with this condition may develop on naturalistic behaviors, specifically, driving. Using a novel Virtual Reality (VR) program, the researchers will gather data on steering behavior in a variety of simulated naturalistic environments. Through the combined use of computer vision, deep learning, and gaze-contingent manipulations of the visual field, this work will test the central hypothesis that changes to visually guided steering behaviors in CB are a consequence of changes to the visual sampling and processing of task-related motion information (i.e., optic flow).

Focused Ultrasound + Virtual Reality for Visual Field Loss After Stroke
Durham, North Carolina
This research will explore if brain stimulation combined with virtual reality therapy improves visual impairment. The stimulation technique is called low-intensity focused ultrasound stimulation (LIFUS). The treatment uses ultrasound to stimulate vision specific parts of the brain. Before this therapy, the participants will get structural brain imaging. Functional brain imaging will be performed before and after the study's completion to measure brain activity response to therapy.
The purpose of this research study is to evaluate patients who have had a stroke between 6 and 24 months ago with a visual field impairment. The duration of active participation in the study is 1.5 months.

Visual Retraining for Stroke-Related Vision Loss
Rochester, New York
This project is intended to collect data using standard clinical tests and psychophysics to quantify the effect of visual cortical damage on the structure of the residual visual system, visual perception, spatial awareness, and brain function. The investigators will also assess the effect of intensive visual retraining on the residual visual system, processing of visual information and the use of such information in real-world situations following damage. This research is intended to improve our understanding of the consequences of permanent visual system damage in humans, of methods that can be used to reverse visual loss, and of brain mechanisms by which visual recovery is achieved.

Vision Training for Cortical Blindness
Rochester, New York
This project aims to develop a novel visual training paradigm for use in visually-intact participants and those sufferings from stroke-induced visual impairments. Our task design is built upon theories of statistical learning to reduce the overall training burden while still producing profound improvements to visual abilities. Efficacy will be first established in visually-intact controls before testing in stroke survivors to assess the feasibility of this form of learning in the damaged visual system.

Frequently Asked Questions
How much do Visual Field Defect clinical trials pay?
Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.How do Visual Field Defect clinical trials work?
After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Visual Field Defect trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Visual Field Defect is 12 months.How do I participate in a study as a "healthy volunteer"?
Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.What does the "phase" of a clinical trial mean?
The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.Do I need to be insured to participate in a Visual Field Defect medical study ?
Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.What are the newest Visual Field Defect clinical trials ?
Most recently, we added Focused Ultrasound + Virtual Reality for Visual Field Loss After Stroke, AV-Stimulation in VR for Vision Impairment and Vision Training for Cortical Blindness to the Power online platform.Popular Searches
