A trabeculectomy is a surgical procedure used to treat glaucoma by creating a new drainage channel in the eye to lower intraocular pressure. This procedure involves creating a small hole in the white part of the eye to allow excess fluid to drain out, reducing pressure and preserving vision. It is often recommended when other treatments, such as medications or laser therapy, have not been effective in controlling intraocular pressure.
only after medications and laser trabeculoplasty have failed to alleviate IOP.

What means the definition trabeculectomy?
The trabeculum is a piece of the eye. A trabeculectomy is the removal of this piece from the eye. Glaucoma patients sometimes have to get this procedure done.
What is trabeculectomy surgery?
The purpose is to lower intraocular pressure in the treatment of glaucoma.
What risks are involved with a trabeculectomy?
Infection and bleeding are risks of any surgery. Scarring can cause the drainage to stop. A third of patients with trabeculectomies will develop cataracts.
When is a trabeculectomy done?
It is used only after medications and laser trabeculoplasty (less invasive procedure that uses a laser to open the blocked trabeculum) have failed to alleviate the pressure.
What does a trabeculectomy involve?
removing a tiny piece of the eye-ball where the cornea connects to the sclera, to create a flap that allows fluid to escape the anterior chamber without deflating the eye.
What is the preparation for a trabeculectomy?
The procedure and its benefits and possible complications are fully explained. Antiglaucoma drugs are prescribed before surgery. Added pressure on the eye caused from coughing or sneezing should be avoided.
What measures are prescribed as aftercare for trabeculectomy patients?
Antibiotic and anti-inflammatory eye drops must be used for at least six weeks after surgery. Additional medicines may be prescribed to reduce scarring.
What surgical filtration technique besides Seton tube surgery is used to treat glaucoma?
Trabeculectomy surgery is performed by making a flap in the sclera of the eye, which serves as an alternative drainage site for aqueous fluid.
Under what circumstances are Seton tube implants employed?
in patients with elevated IOP despite aggressive medical treatment. They are also used when other types of surgery, such as conventional filtration, or trabeculectomy , have not been successful
What does the aftercare for a trabeculectomy involve?
Eye drops, and perhaps patching, will be needed until the eye is healed. The pressure inside the eye will still be monitored. Immediately following the procedure, the patient may experience blurred vision.
What are alternatives to trabeculectomy?
Lasers are now used to treat both closed-angle and open-angle glaucoma. Peripheral iridectomy is used for people with acute angle-closure glaucoma attacks and chronic closed-angle glaucoma
