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.
The purpose is to lower intraocular pressure in the treatment of glaucoma.
Infection and bleeding are risks of any surgery. Scarring can cause the drainage to stop. A third of patients with trabeculectomies will develop cataracts.
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.

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.
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.
Antibiotic and anti-inflammatory eye drops must be used for at least six weeks after surgery. Additional medicines may be prescribed to reduce scarring.
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.
what are alternatives for food additives?
