This study tests a bone marrow transplant from a family donor for children under 21 with severe non-cancer blood disorders like sickle cell disease, bone marrow failure, or immune problems. The goal is to see if the transplant can replace the diseased cells with healthy donor cel…

This study looks at children with suspected or confirmed genetic and metabolic disorders to find new disease-causing gene mutations. Researchers will analyze blood samples for DNA and metabolites, and in some cases take a small skin sample. The goal is to better understand these …

This study screens people with eye diseases to see if they can join other research studies at the National Eye Institute. No treatment is given. Participants undergo eye exams, blood tests, and other procedures to diagnose or evaluate their condition. The goal is simply to determ…

This study enrolls up to 15,000 children with known or suspected endocrine or metabolic disorders, along with their family members. Researchers will collect medical records, blood, saliva, and other samples to identify genetic changes linked to these conditions. The goal is to be…

This study is creating a large collection of blood, urine, stool, and heart tissue samples from 10,000 people with and without heart or metabolic conditions. The goal is to store these samples along with medical information to speed up future research into what causes these disea…

This study tests a special camera that takes super-detailed pictures of the back of the eye (the retina). The goal is to see if this technology can find eye diseases earlier than standard methods. Up to 1,000 people aged 12 and older, with or without eye disease, will have their …

This study tests a new communication tool called 'Let's Get REAL' that helps children and teens (ages 8-17) and their families talk together about stem cell transplant or cellular therapy decisions. The goal is to see if the tool is easy to use and helpful for families. About 60 …

This study aims to learn more about eye diseases by observing and providing standard care to up to 1,000 people over 5 years. Participants receive regular eye exams, tests, and treatments as needed. The goal is to better understand how eye diseases progress and are inherited, not…

This study tests whether artificial intelligence can create simple summaries of eye doctor notes that are easier for patients to understand. About 460 English-speaking adults receiving eye care will get either standard notes or notes plus an AI-generated plain language summary. P…

This study uses MRI scans to look for brain differences in people with metabolic diseases compared to healthy volunteers. Researchers will track changes over time and link them to body fat and other health measures. About 126 adults will take part at Ulm University Hospital. No d…

This study tests a new 4D microscope-integrated OCT system for the first time in people during eye surgery. Researchers want to see if the system is easy to use, safe, and can clearly show eye structures. Five adults having eye surgery will take part. The goal is to improve imagi…

This study gathers standard eye movement and pupil data from 200 healthy volunteers, children, and people with eye or brain conditions using a VR headset called neos™. The headset shows images and tracks where participants look, how their pupils react, and how their eyes move. Th…

This study tests a new, more comfortable eye camera (WiSLO) designed for children and adults. Researchers want to see if it takes better pictures and is less bothersome than current cameras. About 42 people with or without eye disease will have their eyes photographed with both t…

The SMILE study is tracking 10,000 adults aged 18 and older to see how sarcopenia (age-related muscle loss) and metabolic diseases like diabetes influence overall health and lifespan. Researchers will collect data from medical records, tests, and surveys over time. This is an obs…

This study follows 100 children under 18 who are already on a ketogenic diet for conditions like drug-resistant epilepsy, autism, chronic migraine, or brain tumors. Researchers want to see if the diet supports healthy growth, improves symptoms, and boosts quality of life. The die…
