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.
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.
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 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.
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 is the function of corneal scissors?
corneal scissors are used as follows: 1). to enlarge the corneal and corneoscleral incision in cataract surgery and keratoplasty. 2). trabeculectomy (cutting trabecular tissues)
What is a trabeculectomy?
A trabeculectomy involves removing a tiny piece of the eyeball right at the place where the cornea connects to the sclera (the white part), and creating a flap to allow fluid to escape the anterior chamber without deflating the eye.
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 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
