VISUAL IMPAIRMENT

This study compares a technology-enhanced eye exam done remotely (telemedicine) with a standard in-person eye exam to see which detects three leading causes of blindness—glaucoma, diabetic retinopathy, and cataracts—more effectively. About 900 adults who speak English, Spanish, A…

This study tests two treatments—faricimab eye injections or a fluocinolone acetonide implant—to see if they can prevent vision loss in people who had radiation therapy for eye cancer. About 600 participants will be randomly assigned to receive one of the treatments or just be obs…

This study tests whether viewing images on a PowerPoint slideshow can help people with hemianopsia (blindness in half the visual field) after a stroke or brain injury see more of their surroundings. Researchers will measure changes in the visual field using a standard eye test. T…

This study tests a new rehabilitation program that uses multiple senses (like touch and hearing) to help people with ultra low vision. The goal is to improve visual ability, hand-eye coordination, and quality of life. The program is for people with very low vision (20/1600 or wor…

This study tests a new rehab method for people who lost part of their vision after a stroke. It combines gentle electrical brain stimulation with moving visual exercises, sometimes using virtual reality, to try to speed up recovery. The goal is to see if this approach can shrink …

This observational study aims to define a new concept called 'visual frailty' in people aged 60 and older with advanced age-related macular degeneration (AMD). Researchers will measure vision, reading ability, mental health, and daily function to see how these factors relate. The…

This study looks at how blind people use a white cane to sense the world around them, like feeling for curbs or obstacles. Researchers will test touch perception on a rod and measure brain activity with EEG and MRI. The goal is to understand how the brain treats the cane as an ex…

This study involves 150 people with diabetic macular edema (DME) who are either starting treatment with anti-VEGF injections or a dexamethasone implant, or have not been treated before. Researchers will measure various substances in the blood and use eye scans to see if these mar…
