Surgery comparison for advanced angle-closure glaucoma
Part of Eyes & vision clinical trials.
This trial compares two types of glaucoma surgery—trabeculectomy versus a different procedure that also opens the drainage angle—for people with advanced primary angle-closure glaucoma. It aims to see which surgery controls eye pressure and preserves vision better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between 45 and 80 years old.
- Have advanced primary angle-closure glaucoma, including blocked drainage angle (PAS) in about 180° or more, and eye pressure higher than 21.
- Have signs of glaucoma damage: optic nerve changes and a specific pattern of visual field loss on standard vision testing.
- Have relatively clear vision (no more than mild cataracts) and good eyesight without correction (meeting a specific chart score).
- Have eye measurements like an eye length of at least 20 mm, and no history of eye injury or eye surgery.

This trial compares two types of eye surgery—one that removes the cataract and opens blocked drainage channels, and another that creates a new drainage pathway. It aims to find which works better for people with both glaucoma and cataracts.
This study tests a new surgery that combines cataract removal with a glaucoma procedure to lower eye pressure in people with primary open-angle glaucoma. It's for people whose eye pressure is controlled with 1 to 4 medications but who also have significant cataracts.
This study looks at how your eye's drainage angle changes after glaucoma surgery. It helps doctors understand what happens to the front part of your eye after procedures like laser or surgery to open the drainage area.
This trial studies a new tube-shunt surgery (SCTSC) against the standard trabeculectomy for people with open-angle glaucoma that is not controlled by eye drops. It is only for people who have already had cataract surgery.
This trial compares two types of glaucoma surgery to see which one works better for people with specific kinds of open-angle glaucoma whose eye pressure isn't controlled by eye drops or laser.
This trial tests a surgery called GATT combined with goniosynechiolysis to treat glaucoma patients whose eye drainage angle is closed due to scarring. It aims to lower eye pressure when medicines alone aren't working.
