Blindness (disorder)

This study compares two types of weight-loss surgery (gastric bypass and gastric banding) with an intensive diet and exercise program for controlling type 2 diabetes in moderately obese adults aged 25 to 55. The goal is to see which approach works best for improving diabetes and …

This Phase 3 trial tests a single injection of Ixo-vec gene therapy in 311 people with wet age-related macular degeneration (AMD). The goal is to see if it can maintain or improve vision as well as standard aflibercept injections, but with fewer follow-up treatments. Participants…

This study tests whether a device called Sonablate can safely use high-intensity focused ultrasound (HIFU) to treat vein problems like varicose veins, leg ulcers, and certain birth defects. About 30 adults with these conditions will receive the treatment, which does not involve c…

This study follows 23 people with wet age-related macular degeneration who received a single dose of ADVM-022 gene therapy in an earlier trial. Researchers are checking how safe the treatment is over time and whether it continues to control the disease, potentially reducing the n…

This study tests whether an AI-assisted screening tool can detect visual impairment more accurately and efficiently than traditional methods in community settings. About 400 adults aged 50 and older will undergo vision screening and provide feedback. The goal is to see if the AI …

This study tests whether phentolamine eye drops can improve vision in low light for people who had laser eye surgery and now see glare, halos, or starbursts at night. About 200 adults will use the drops or a placebo every evening for two weeks. The main goal is to see if more peo…

This study tests whether wearing a virtual reality headset during laser treatment for varicose veins can lower anxiety and pain. About 100 adults will use VR during the procedure, and researchers will measure their heart rate, blood pressure, and comfort levels. The goal is to se…

This study tests a device that uses real-time sound feedback to help people with vision loss fix their gaze on a target. Participants hear sounds that guide their eyes back to center when they drift. The goal is to improve the quality of eye imaging by reducing blur from eye move…

This study looks at whether traditional exercises like Tai Chi and Baduanjin can help visually impaired university students improve their balance, mood, and quality of life. Ninety participants will be split into three groups: Tai Chi, Baduanjin, or regular physical education cla…

This study aims to find the genes that cause inherited hearing loss by analyzing DNA from 24,000 people in large Pakistani families. Researchers will compare affected and unaffected family members to identify new deafness genes. The goal is to improve genetic testing and counseli…

This study aims to help adults aged 40 and older in Upper Manhattan get better eye care. It will offer free eye screenings at local health centers and senior centers, and provide support like scheduling appointments and transportation. The goal is to see if this extra help leads …

This study aims to find better ways to measure how retinitis pigmentosa (a genetic eye disease that causes vision loss) progresses over time. Researchers will use advanced imaging and vision tests in 40 people with specific genetic forms of the disease. The goal is to identify re…

This study looks at how to better check vision in older adults (65+) who come to the hospital after a fall. Falls are common and costly, and poor eyesight can double the risk of falling again. Researchers will talk to patients, carers, and health professionals to develop a practi…

This study looks at how the brain changes and adapts after losing central vision, which happens in conditions like macular degeneration. Researchers are testing different training tasks in 120 healthy adults aged 18-30 to measure improvements in eye movements and focus. The goal …

This study tests a new computer-based visual training task for people who have lost part of their vision due to a stroke. Participants watch moving patterns on a screen and learn to detect motion direction, with the goal of improving visual abilities. The study first checks if th…

This study tests whether stimulating the visual part of the brain can create visual sensations in blind volunteers. Five adults who are blind will have a device implanted in their skull to deliver tiny electrical pulses. The goal is to learn where and how much stimulation is need…

This study follows 61 people who previously used the REVISYON SDS 100 device for mild-to-moderate cataract. Researchers will check for side effects and measure vision changes over about 20 months. No new treatment is given; the goal is to see if the device stays safe and works we…

This study offers free vision screenings to underserved adults over 40 living in affordable housing in Harlem and Washington Heights. The goal is to find eye problems like glaucoma, cataracts, and diabetic retinopathy early and connect people with follow-up care. About 749 partic…

This study is working to create a simple screening test to find cerebral vision impairment (CVI) in babies and young children. CVI is a leading cause of vision problems in kids, often linked to brain injuries or conditions. Researchers will study 600 children to better understand…

This study reviews the medical records of 2,000 people in Upper Egypt who applied for visual disability certification between 2020 and 2024. Researchers will analyze eye exams and tests to find the most common diseases causing severe vision loss. The goal is to understand which c…
