2024年5月20日 · A bleb is a small fluid-filled blister that forms on the surface of the eye after glaucoma surgery and serves as a drainage site for excess fluid. Proper post-operative care is crucial for the success of a bleb, including avoiding eye rubbing and following medication and follow-up appointment schedules.

2018年10月31日 · After this point—and during nor­mal follow-up—common signs of bleb leakage include a newly tearing eye, a noticeable change in vision, redness, or a drop in intraocular pressure (IOP) from baseline.

2024年7月3日 · A trabeculectomy bleb is a surgical intervention for treating glaucoma, an eye condition that damages the optic nerve and can result in vision loss. The procedure involves creating a small, fluid-filled pocket, or bleb, on the eye’s surface to …

2022年4月19日 · Bleb needling is generally considered a safe outpatient procedure performed in the doctor's office. When conventional glaucoma surgery called a trabeculectomy (a type of microsurgery) is performed, in essence your doctor is making a new drain pipe so fluid from the inside of the eye can be directed to the outside of the eye, thus relieving ...

2024年12月3日 · Glaucoma surgery bleb refers to a small, fluid-filled blister that forms on the surface of the eye following glaucoma surgery. It acts as a drainage system to help lower the intraocular pressure and prevent further damage to the optic nerve.

2024年1月12日 · The bleb needling (and bleb revision) procedure cuts the scar tissue and frees the trap door and bleb, thus re-establishing aqueous flow into the bleb. Doing so decreases the eye pressure, which in turn reduces the risk of further optic nerve damage from glaucoma.

Trabeculectomy is a type of glaucoma surgery performed on the eye that creates a new pathway for fluid inside the eye to be drained. This is an outpatient procedure performed in the operating room. It is used to prevent worsening of vision loss due to glaucoma by lowering eye pressure.

Bleb leaks are part of all surgical glaucoma practices and can occur after any filtering surgery, during both the early and late postoperative periods. Because bleb leaks can lead to serious complications, proper detection and successful management are paramount.

2012年11月19日 · Trabeculectomy surgery for glaucoma results in the creation of a drainage “bubble” under the upper eyelid. Aqueous fluid flows from the eye into this bubble, which is called a bleb. The aqueous fluid is absorbed into tiny blood vessels, keeping eye pressure low.

Bleb related infections (BRI) are a common problem and will be encountered by both comprehensive ophthalmologists and glaucoma specialists alike. BRI may develop days to years after surgery and can be a devastating complication of glaucoma filtering surgery leading to permanent visual loss.
