Visual field defect, peripheral

This study compares a new virtual reality goggle device (VisuALL) to the standard Humphrey Visual Field test for measuring peripheral vision in children. Researchers will enroll 1000 healthy children and those with eye conditions, testing them during a routine eye appointment. Th…

Researchers at Georgetown University are testing whether a mild electrical brain stimulation called transcranial random noise stimulation (tRNS) can boost the effects of visual training in people who have lost part of their vision from brain damage. The study includes 30 adults w…

This study tests whether a simple PowerPoint program that shows moving images in the blind part of a person's vision can help expand their visual field. The trial enrolls 40 adults with hemianopsia (partial blindness) after stroke or brain injury. Participants will watch slides w…

This study tests a new rehabilitation method for people who lost part of their vision after a stroke. It combines gentle electrical brain stimulation with visual exercises, sometimes using virtual reality, to try to speed up recovery of sight in the blind area. The study involves…

This study tests special glasses with high-power prisms that shift images from blind spots into the wearer's remaining vision. Researchers will try different designs to see which best expands the field of view and helps people detect obstacles while walking. The trial involves ab…

This study tests whether a home-based computer training program can improve vision in people who have lost part of their visual field due to stroke, traumatic brain injury, or brain tumor. Researchers will use brain scans to understand how the brain changes with training. The stu…

This study uses a virtual reality driving simulator to see how people with vision loss from a stroke steer a car. Researchers will compare driving accuracy between 40 participants with and without vision loss. The goal is to understand how the brain adapts to missing parts of the…
