How do you describe a trabeculectomy bleb?

How do you describe a trabeculectomy bleb?

Trabeculectomy is a filtering surgery where an ostium is created into the anterior chamber from underneath a partial thickness scleral flap to allow for aqueous flow out of the eye. The aqueous flows into the subconjunctival space, usually leading to an elevation of the conjunctiva, referred to as a filtering bleb.

What is Encysted bleb?

In the first 2 months after trabeculectomy, elevated intraocular pressure (IOP) associated with a high bleb develops in some patients. This has been referred to as an encysted bleb, and some have recommended surgical techniques to repair it and to restore controlled IOP.

How would you describe bleb?

In general, bleb appearance can be classified clinically as diffuse, cystic, encapsulated and flattened. Good intraocular pressure (IOP) control (<21 mm Hg) after filtration surgery was commonly found to be associated with low lying diffuse blebs.

What is a bleb in glaucoma surgery?

With traditional glaucoma surgery (trabeculectomy), a blister-like fluid collection (called a “bleb”) must be present on the surface of the eye for the surgery to work. Aqueous fluid (the fluid inside the eye) flows through the fistula into this bleb where it then finds its way out of the eye.

What are the different types of glaucoma surgery?

What Are the Different Types of Surgery for Glaucoma?

• Laser Surgery.
• Electrocautery.
• Drainage Implant Surgery.
• EX-PRESS® Mini-shunt.
• Ahmed Glaucoma Valve.
• Contact Transcleral Laser Cycloablation (CTLC)

What is bleb failure?

Blebs can fail because the internal ostium is blocked by the iris, a membrane or fibrin and vitreous. Episcleral fibrosis can cause closure of the flap margins lining the bleb and can cause an encapsulation. Collagen within the bleb occurs in 10% to 14% of cases.

How do you get rid of blebs?

Popular treatments include:

1. Saline solution. To remove the blockage, soak the nipples in a solution of salt and warm water.
2. Nipple massage. Gently massage the nipple to release the blister.
3. Warm compress.
4. Olive oil.
5. Expressed milk.
6. Frequent breast-feeding.
7. Hospital-grade breast pump.
8. Soothing ointment.

What causes an eye bleb?

There are various factors which can cause this, which include having a bleb leak, suffering from conjunctivitis or blepharitis, wearing contact lenses, having a previous bleb related infection, having had a second operation on the bleb, using antibiotics, and having diabetes.

What are the different types of trabeculectomy?

One variation of trabeculectomy is trabeculectomy performed with the addition of an EX-PRESS shunt. This is a small metal shunt that is inserted into the eye wall to allow fluid to drain from the inside of the eye and underneath the “trapdoor,” thus creating a “bleb.”

What are the risks of a trabeculectomy bleb?

Trabeculectomy blebs can leak, which is dangerous because of the risk of infection. A leak can also cause hypotony maculopathy and blurred vision. Furthermore, blebs can some-times expand across the globe in ways that irritate the patient’s eye or cause a cosmetic problem.

What is the role of functional filtering bleb after trabeculectomy?

In early stage after trabeculectomy, the maintenance of functional filtering bleb can make the patients’ intraocular pressure be controlled well, which can improve the surgical results.

How effective is trabeculectomy for lowering eye pressure?

When successful, trabeculectomy is very effective at lowering eye pressure and is considered one of our “gold standard” procedures, especially for patients with moderate to advanced glaucoma. Often, the “trapdoor” or “bleb” may scar over as part of the body’s natural healing process.
