During trabeculectomies, doctors create new openings in the drainage angle of the eye to allow fluid to drain, notes WebMD. They cover the opening with tissue taken from other parts of the eye, and as fluid passes through this new opening, the tissue forms a bleb, or a bubble, through which fluids can drain while avoiding clogged drainage channels.Continue Reading
Doctors use trabeculectomies when other treatments and medications fail to reduce the symptoms of conditions that put pressure on the eye and damage eyesight, such as open-angle and chronic closed-angle glaucoma, states WebMD. Some people need to have multiple surgeries, and trabeculectomies do not cure glaucoma. People who have diabetes, previous eye surgeries, African-Americans and children with congenital glaucoma do not see the same success rate after trabeculectomies as other patients.
Doctors continue to monitor the drainage from the eyes in patients who have had trabeculectomies, and may prescribe antibiotics that are applied to the eyes, according to WebMD. People sometimes have to wear shields to protect their eyes while sleeping for up to a month, and doctors may prescribe corticosteroid medications to prevent inflammation. While some pain is normal after the procedure, people who suffer severe pain after trabeculectomies should contact their doctors immediately.Learn more about Vision
