Iris disorder

This study tests a personalized treatment for advanced melanoma using a patient's own immune cells, called tumor-infiltrating lymphocytes (TIL), which are boosted with a protein called CD40L. After a short course of chemotherapy to make room, the enhanced cells are infused back a…

This study compares two devices used during cataract surgery to treat open-angle glaucoma. About 194 adults with mild to moderate glaucoma and cataracts will receive either the ELIOS device or a competitor device. The main goal is to see which one lowers eye pressure more effecti…

This study compares two FDA-approved laser treatments for open-angle glaucoma: the standard SLT and a newer, non-contact version called DSLT. Both aim to lower eye pressure and prevent vision loss. About 172 adults with glaucoma or high eye pressure will be randomly assigned to o…

This study compares two small implants (XEN-63 and PRESERFLO) placed during a quick surgery to lower eye pressure in adults with open-angle glaucoma. About 166 participants will be randomly assigned to one implant and followed for 2 years. The goal is to see if PRESERFLO works as…

This study compares three types of glaucoma surgery (Hydrus Microstent, incisional goniotomy, and excisional goniotomy) done at the same time as cataract surgery. About 243 adults with mild to moderate open-angle glaucoma will take part. The goal is to see which surgery lowers ey…

This study is testing a special laser called ELIOS to treat glaucoma at the same time as cataract surgery. The laser creates tiny channels in the eye to help fluid drain and lower eye pressure. About 46 adults with both cataracts and open-angle glaucoma will take part. The goal i…

This study tests whether a tiny drainage device called the Preserflo MicroShunt can lower eye pressure as well as the standard trabeculectomy surgery in adults with open-angle glaucoma. One hundred participants will be randomly assigned to receive one of the two procedures and wi…

This study tests whether a weak electrical current applied to the eye's surface can improve vision in people with open-angle glaucoma. Fifty adults with worsening vision loss will receive either real or sham stimulation over several sessions. The goal is to see if this safe, non-…

This study tests a device called the Tran cannula, used during cataract surgery to clean away debris from the eye's drainage system in patients with pseudoexfoliative glaucoma. The goal is to see if it lowers eye pressure better than standard irrigation. Fifty-eight adults with b…

This trial tests a tiny device called the VisiPlate shunt to help drain fluid and lower eye pressure in people with open-angle glaucoma that hasn't responded to other treatments. About 165 adults will receive the implant and be followed to see if their eye pressure drops by at le…

This study tests a device called the Calibreye System, a small implant placed in the eye to help drain fluid and lower pressure in people with open-angle glaucoma. Researchers will check if it is safe and works well over 12 months in 60 adults. The goal is to see if the device ca…

This study tests if two devices placed in the eye can safely lower eye pressure in people with moderate to severe open-angle glaucoma. Participants have not responded well to drops or laser and are considering surgery. The goal is to see if these implants can be a less invasive a…

This study tests a smartphone app that uses artificial intelligence to detect 16 different eye diseases from photos taken with the phone. The AI works entirely on the device, so no internet is needed. Researchers will compare its accuracy to eye doctors and see if non-medical use…

This study looks at whether a laser treatment called DSLT can reduce the natural ups and downs of eye pressure throughout the day in people with glaucoma. Researchers will measure eye pressure at three times during one day before the laser and again six months after. The goal is …

Infectious uveitis is a serious cause of blindness, but current tests often miss the culprit. This study uses a broad panel of molecular tests to detect bacteria, viruses, and fungi in eye fluid from 100 patients with suspected infectious uveitis in China. The goal is to map whic…

This study follows 800 children born with eye malformations like microphthalmia, anophthalmia, aniridia, or anterior segment defects. Researchers will track their vision, brain development, and overall health for up to 10 years to better predict outcomes. No new treatments are be…

This study aims to find biological markers (biomarkers) in blood, tears, and eye cells from 110 adults with seven rare eye diseases. Researchers will compare these markers between patients and healthy controls to see if they differ and if they relate to disease symptoms. The goal…

This study follows 60 children aged 7-12 for three years to measure their daily visual environment, including how far they look, light brightness and color, and eye movements. Researchers want to find which factors most influence the development and worsening of nearsightedness (…

This study aims to collect DNA samples and detailed eye exam data from 1,000 people with rare inherited eye diseases like aniridia, Best disease, and albinism. Participants provide a saliva or blood sample and share their eye health records. The goal is to expand a research repos…

This study uses a one-time survey to learn about the eye and body symptoms of people with congenital aniridia, a rare genetic condition that affects the iris. Researchers want to see how much patients understand about their own disease. About 100 patients of all ages will take pa…

This study takes skin or blood cells from 20 people with eye malformations and turns them into stem cells, which are then grown into tiny 3D eye-like structures (organoids) in a dish. Researchers will study these mini eyes to understand what goes wrong during development and test…

This study follows 132 adults having glaucoma surgery to see how their quality of life changes over six months. Patients fill out a questionnaire about vision-related daily activities before and after surgery. The goal is to compare different surgical techniques from the patient'…

This study aims to uncover genetic mutations or variations linked to uveitis, an inflammatory eye disease. Researchers will collect blood samples from 1,500 patients with uveitis (including infectious types) and analyze their DNA. The goal is to better understand what causes the …

This study compares two common inhaled anesthetics, sevoflurane and desflurane, in 50 adults undergoing robotic-assisted abdominal surgery. Researchers will measure airway pressure to see which drug better protects lung function. The goal is to find the safer option for patients …

This study looks at two treatments made from patients' own blood—autologous serum and growth factor-rich plasma—to see which helps heal the cornea better in people with aniridia, a rare eye condition. Researchers will test these treatments on corneal cells in the lab, using blood…

This study looks at whether blood backing up in the veins during heart surgery can predict acute kidney injury. Researchers will monitor 114 adults having elective heart surgery, using ultrasound to check for venous congestion. The goal is to find an early warning sign to prevent…

This study uses a special eye scan called OCT angiography to look at iris tumors in 100 people. Researchers want to see if this scan can tell the difference between harmless and cancerous growths better than current methods. Participants include people with iris tumors and health…
