What is a revision of trabeculectomy?

Revision trabeculectomy is used to describe any surgical intervention subsequent to an existing trabeculectomy. Mostly, it is used to describe resurgery for failure of trabeculectomy, as defined by inadequate pressure control. Revision may also be performed for unsafe, uncomfortable or leaking blebs.

What is a bleb procedure?

Aug 23, 2011. 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.

Do eye blebs go away?

“In most cases, you can leave them alone. You can just simply control the elevated intraocular pressure [IOP] with anti-glaucoma medication, particularly aqueous suppressants, and the bleb will gradually resume functioning in most cases.”

What happens after a bleb needling?

Your eye may be sore for the next few days. Immediately after the procedure, your eyesight is usually not very clear. However, your eyesight usually recovers over the days and weeks that follow. Rarely, the needling treatment can make the pressure in your eye very low permanently.

What is 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.

Can trabeculectomy be repeated?

Repeat trabeculectomy with MMC has high success and low complication rates in patients with previously failed trabeculectomy in spite of the need of higher number of anti-glaucoma medications.

How long is vision blurry after trabeculectomy?

Your eyes may be blurry for up to 6 weeks after surgery. As this goes away, your vision will probably be as good as it was before surgery. But you may need to change your glasses or contact lenses.

How many times can a bleb needling be done?

Normally, we see him every 1 to 2 weeks until a stable, well-functioning bleb is present. We repeat needling with MMC if necessary up to three times, depending on the initial response. In most if not all studies, success was achieved with more than one needling procedure.

What causes eye blebs?

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.

How can I fix my bleb?

What does an eye bleb look like?

The bleb typically has a milky-white appearance with loss of clarity, and you may observe a pseudohypopyon within the bleb. A positive Seidel’s test is common. Some pa-tients may have hypotony, and even a flat anterior chamber.

What is an encapsulated bleb?

Encapsulation of the filtering bleb occurs as a complication of glaucoma filtering surgery in 8.3-28% of all eyes filtered, often between 2-4 weeks after surgery. It has a characteristic clinical appearance–highly elevated localized bleb, prominent surface vessels and patent sclerostomies on gonioscopy.
