Posterior polymorphous corneal dystrophy

This study tests whether giving a laser treatment (transscleral cyclophotocoagulation) to lower eye pressure before a Boston keratoprosthesis (a plastic cornea implant) can prevent or slow glaucoma. Twenty adults who need the implant will receive one of two laser types 4-8 weeks …

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 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 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 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 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…

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…
