Blindness (disorder)

This study tests a gene therapy called Ixo-vec in the second eye of people with wet age-related macular degeneration (AMD) in both eyes. Fifteen adults aged 50 and older will receive a single injection in the second eye and be followed for about 5 years. The goal is to see if the…

This phase 3 study tests a single injection of Ixo-vec gene therapy against standard aflibercept injections in 284 people with wet AMD. The goal is to see if Ixo-vec can maintain or improve vision while reducing the need for repeated eye injections. Participants must be at least …

This study tests whether injecting a person's own bone marrow stem cells into or near the eye can help treat various retinal and optic nerve diseases, including age-related macular degeneration, retinitis pigmentosa, and glaucoma. Participants receive stem cell injections via dif…

This phase 3 trial tests an experimental drug called sepofarsen in 32 people with Leber congenital amaurosis (LCA), a rare genetic condition that causes severe vision loss from birth. The drug is injected into one eye, while the other eye gets a placebo, to see if it safely impro…

This early-stage trial is testing a brain implant designed to create artificial vision in people who are blind. Five participants will have a wireless device surgically placed in the part of the brain that processes vision. The study will check if the device is safe and whether i…

This pilot study is testing a brain implant that uses tiny electrodes to stimulate the visual cortex, aiming to create simple visual perceptions (phosphenes) in blind individuals. Five participants will undergo a small skull opening to receive the implant. The goal is to see if t…

This study tests whether levosulpiride, a drug already used for other conditions, can safely improve vision and reduce retinal swelling in people with diabetic retinopathy and diabetic macular edema. About 120 adults aged 40-69 with mild to moderate eye damage will receive either…

Researchers at the University of Rochester are testing a home-based computer program that trains people to detect visual stimuli in their blind field. The trial enrolls adults who have lost part of their vision because of damage to the brain's visual cortex, often from a stroke. …

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 tests a wearable device that uses directional sound to help people with low vision detect obstacles. Fifty participants with normal vision will wear a blindfold and walk a path with obstacles, once with the device and once without. The device emits tones that get loude…

This study is testing whether a simple vision screening program in general practice can help detect vision loss early in adults over 70 who have at least one chronic condition. Participants will have three vision tests done by their GP or nurse, then visit a collaborating opticia…

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…
