PRIMARY OPEN ANGLE GLAUCOMA

This study tests a gel stent implant designed to lower eye pressure in people with glaucoma. About 130 adults aged 45 and older will receive the stent through one of two surgical methods. Researchers will check safety and how well the stent reduces eye pressure over 12 months.

This study is checking whether a small metal implant called the Hydrus Microstent stays in the right place after being placed during cataract surgery. The implant is designed to help drain fluid from the eye and lower pressure in people with open-angle glaucoma. Researchers will …

This study tests a small implant called the PRESERFLO™ MicroShunt XI in people with primary open-angle glaucoma whose eye pressure remains high despite maximum medication. The implant is placed under the eye's surface to drain fluid and lower pressure. Researchers will check if i…

This study looks at whether adding a combination of two eye drops (netarsudil and latanoprost) after laser treatment works better than adding just one drop (latanoprost) for lowering eye pressure in people with glaucoma. About 36 adults with mild to moderate glaucoma will take pa…

This study tests whether adding a physical activity program to standard care can improve health in older women who have three conditions: underactive thyroid (hypothyroidism), glaucoma (high pressure in the eyes), and fatty liver. Researchers will measure changes in eye pressure,…

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 tests whether a quick laser treatment called DSLT can help people with glaucoma or high eye pressure use fewer daily eye drops. Sixty adults whose eye pressure is already controlled with 1-3 types of drops will receive the laser in one or both eyes. Researchers will ch…

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 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 looks at whether lifestyle changes (diet and exercise) plus CPAP therapy can reduce eye pressure in people with glaucoma, sleep apnea, and obesity. Forty participants will be split into two groups: one gets CPAP alone, the other gets CPAP plus lifestyle changes. The ma…

This study tests a new tool called the MIST device to lower eye pressure in people with primary open-angle glaucoma. About 25 adults aged 40 and older whose eye pressure is not well controlled with eye drops will receive the procedure. Researchers will check how safe the device i…

This study tests a device called the OMNI 3.1 Surgical System to see if it safely lowers eye pressure in people with primary open-angle glaucoma. About 25 adults aged 45 and older will take part. The main goal is to check if eye pressure drops by at least 20% three months after s…

This study tests whether metformin, a drug used for diabetes, can protect the optic nerve and slow vision loss in people with glaucoma. 125 participants with worsening glaucoma will take either metformin or a placebo for 24 months. The goal is to see if metformin can slow the thi…

This study tests a new smart contact lens that measures eye pressure continuously for 24 hours, compared to standard spot checks. It involves 12 adults with glaucoma or high eye pressure. The goal is to see if the lens provides accurate readings day and night, which could lead to…

This study is testing whether measuring blood flow in the retina can help detect early glaucoma. Researchers will use special dyes and imaging to see how blood vessels respond to oxygen. The goal is to find a reliable early warning sign for the disease. About 90 adults with early…

This long-term study is looking for the best methods to detect glaucoma and track its worsening over time, especially in people with nearsightedness (myopia) and those of African or European descent. Researchers will use advanced eye imaging to monitor changes in the back of the …

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 …

This study will use advanced eye scans (OCT and OCTA) to compare the structure and blood flow of the choroid and retina in people with two main types of glaucoma: primary angle-closure disease and primary open-angle glaucoma. Researchers aim to better understand how these conditi…

This study looks at how glaucoma affects sleep, mood, alertness, and thinking by changing how the eye responds to light. Researchers will compare 120 adults with glaucoma to healthy volunteers aged 45-75. Participants will wear a sleep tracker and visit a lab to test their thinki…

This study aims to understand the natural bacteria living on the surface of the eye in both healthy people and those with certain eye conditions. Researchers will collect eye swabs from 500 adults in middle Tennessee to build a database of what a normal eye microbiome looks like.…

This study looks at whether damage to the glycocalyx, a protective lining inside blood vessels, is linked to glaucoma. Researchers will compare 50 people with glaucoma to 50 without, using a non-invasive device to measure this lining under the tongue. The goal is to see if blood …

This study looks at how vision loss from glaucoma affects how often and how far older adults get out and about, known as 'life space.' Researchers will use questionnaires and vision tests to compare people with glaucoma to those without. The goal is to understand the real-world i…

This pilot study is testing whether a non-contact imaging technique called Brillouin microscopy can measure corneal stiffness in people with glaucoma. Researchers will compare these measurements between patients with high-tension glaucoma, normal-tension glaucoma, and healthy con…
