Cortical blindness

This study tests whether a training program that pairs sounds with visual cues can help people who have lost part of their vision due to brain damage (cortical blindness). Participants will do 12 sessions where they see and hear stimuli in their blind area, plus virtual reality t…

This study tests a caregiver-led digital program called VIPPSTAR designed to improve vision and brain development in infants at risk of or with visual impairment. The program provides personalized activities integrated into daily routines, supported by remote coaching. Researcher…

This trial tests a new device called the enVVe system, a catheter-based artificial valve placed in leg veins to treat chronic venous insufficiency. The study will enroll 220 people with severe symptoms like skin changes or leg ulcers. Participants are randomly assigned to receive…

This study tests a training technique that uses repeated flashes of light and bursts of sound to help people who have lost part of their vision after a stroke. The goal is to see if this training can improve how much they can see and how their brain responds. The study will inclu…

This study tests a 3-week digital program delivered through the VIPPSTAR app, designed to help children and adolescents with visual impairment build a healthier body image and become more critical of social media content. Participants aged 10-18 will complete daily exercises and …

This study tests a 12-week adapted physical activity program for children and adolescents aged 10-17 with visual impairment. The program includes supervised school-based exercise sessions and home-based activities, along with peer-group meetings to promote social inclusion. Resea…

This study explores how visual impairment affects movement and daily activities, and tests a wearable system called VIS4ION that provides audio and touch cues to help users navigate. Researchers will enroll 150 adults with visual impairment and healthy controls to see if the devi…

This study tests whether Meta AI glasses, connected to the Be My Eyes network, can help people with permanent vision loss walk and move around more easily. The glasses describe scenes and objects in real time. Fifty participants will use the glasses and report changes in their qu…

This study looks at whether a common procedure for varicose veins—called endovenous ablation—can also reduce knee pain in people aged 80 and older. The researchers will follow 50 participants for one year after treatment, measuring pain and knee function. The goal is to see if im…

This observational study will track 87 people who are already scheduled to receive treatment with the Recana Thrombectomy Catheter System for blocked veins in their legs. The goal is to see how safe the device is and how well it works at clearing the blockages during the procedur…

This study investigates whether people with central or peripheral vision loss develop heightened senses of taste and smell. Researchers will measure brain responses to sweet and vanilla flavors in 50 visually impaired adults and compare them to sighted controls. The goal is to un…

This study looks at whether shifting text to a different part of the eye can help people with central vision loss read faster and more accurately. Researchers will test 100 participants with conditions like macular degeneration using various reading tasks. The goal is to find bet…

This study at Stanford University will test how the brain responds when visual information is turned into patterns of sound or touch. Two hundred blind and sighted participants will use special devices (BrainPort and AI Sight) for 5 weeks. Researchers will use brain scans and per…

This study looks at children born prematurely who had retinopathy of prematurity (ROP), a disease that can cause blindness. Some were treated with laser, others with injections, and some had ROP but no treatment. Researchers will compare their vision and retina structure to see w…

This study will follow 50 adults with varicose veins and chronic knee pain who are scheduled for standard vein treatment (laser or radiofrequency ablation). Researchers will measure changes in knee pain, stiffness, and function before and after the procedure. The goal is to see i…
