Mosaic trisomy 13

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…

Researchers are collecting blood samples from pregnant women at higher risk of having a baby with a chromosomal condition. The goal is to develop a noninvasive prenatal test that looks at cell-free DNA in the mother's blood to detect Down syndrome. Participants give blood between…

This study is testing a new blood test that looks for fetal cells in the mother's blood to detect genetic conditions like Down syndrome. The test will be compared to standard diagnostic methods such as amniocentesis or newborn testing. The study involves 1,000 pregnant individual…

This study tests a new eye imaging device (VG200D OCT) that takes detailed pictures of the retina. It compares these images to standard dye-based images (FA/ICGA) to see if the new device works just as well. About 30 adults with retina problems will take part. The goal is to see …

This study tests a special camera that takes detailed images of the retina using many wavelengths of light. Researchers hope it can find early signs of eye diseases like age-related macular degeneration, diabetic retinopathy, and glaucoma. About 1,000 adults in Melbourne, Austral…

This study uses a special camera (adaptive optics) to take detailed pictures of the back of the eye in people with inherited retinal diseases. Researchers want to see how individual cells change over time and after treatments. About 200 participants aged 5 to 70 will be observed,…

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 …
