This study is testing a new eye imaging device called the VG200D, which uses advanced technology to take detailed pictures of the eye. Researchers want to see if it works as well as a standard device for measuring parts of the eye in people with glaucoma, retina problems, corneal…

This study looks at how the immune system changes with age and how that affects the risk of infections in people 60 and older. Researchers will collect blood, urine, stool, and other samples from elderly patients with infections and healthy older adults. By analyzing immune cells…

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 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 aims to improve how doctors evaluate and manage people who have been exposed to bioterrorism agents (like anthrax) or emerging infectious diseases (like SARS or new flu strains). Up to 200 participants, including patients and healthcare workers, will be monitored and t…

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 long-term study collects data from over 100 eye clinics in Germany to see how corneal transplant surgeries have changed since 2001. Researchers track the number of surgeries, the types of procedures used, and the reasons people need them. The goal is to understand trends, no…

This study tests a new, lightweight ultrasound device called NeoDoppler that can be gently placed on a newborn's soft spot (fontanelle) to continuously measure blood flow in the brain. Researchers will enroll 180 preterm and full-term infants, including those with conditions like…

This study is looking at whether early signs of inflammation in the blood can help identify which patients with infections are at risk for serious complications like sepsis. Researchers will follow 4,200 adults with confirmed or suspected infections, as well as healthy controls, …

This pilot study is measuring prednisolone levels in 120 people with inflammatory diseases like thyroid eye disease, vasculitis, COPD, asthma, and others. Participants take high-dose prednisolone as part of their routine care, and researchers take timed blood samples to see how t…

This study looks at how the antibiotic ceftazidime avibactam behaves in 30 children with severe infections who are in intensive care, some on life support. Researchers will measure drug levels in the blood to understand the right dose. The goal is to improve treatment for life-th…

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 looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…

This study looks at how the antifungal medicine caspofungin behaves in children with severe infections, especially those with liver problems or on life support like ECMO. Researchers will measure drug levels in the blood to understand dosing needs. About 60 children in intensive …

This study will collect data from 2,000 children admitted to pediatric intensive care units (PICUs) with severe infections across major Chinese cities. Over 10 years, researchers will track which germs cause these infections, how they are treated, and patient outcomes. The goal i…

This study looks at two common antibiotic combinations given to hospitalized adults with infections: vancomycin plus piperacillin-tazobactam, or vancomycin plus cefepime. The goal is to see if one is less likely to cause kidney injury than the other, using more sensitive markers …

This study gathers eye scan images from 180 people with healthy eyes or eye diseases like glaucoma and retinal disease. The goal is to collect data using a new optical coherence tomography (OCT) device called A10900. No treatment or medication is given. The information will help …

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…
