VISUAL IMPAIRMENT

This study compares a technology-enhanced eye exam to a standard optometric exam for detecting three leading causes of blindness: glaucoma, diabetic retinopathy, and cataracts. About 900 adults at a Federally Qualified Health Center will be randomly assigned to one of the two exa…

This phase 3 trial tests whether two different eye treatments can prevent vision loss in people who have had radiation therapy for a type of eye cancer called uveal melanoma. The study will compare faricimab injections given every 3 months, a fluocinolone acetonide implant placed…

This pilot study tests whether a non-invasive headset that delivers mild electrical stimulation to nerves behind the ear can safely improve sleep in adults who are blind or severely sight impaired. Sixty participants will use the device for 30 minutes a day, five times a week for…

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 is testing a multi-sensory rehabilitation program for people with ultra low vision (visual acuity of 20/1600 or worse). The program includes training to use remaining vision better and to combine input from different senses. Researchers hope this will improve daily fun…

This study looks at how blind people use a white cane to sense the world around them, not just to move. Researchers will test how well users can feel where a touch happens on the cane and measure brain activity during these tasks. The goal is to understand how the cane becomes an…

This observational study seeks 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 in 20 participants to develop a vis…

This study is for people with diabetic macular edema, a condition that causes vision loss. Researchers want to see if certain substances in the blood and patterns on eye scans can predict how well a patient will respond to two common treatments: anti-VEGF injections or a dexameth…
