Trabeculectomy is a surgical procedure in which part of the trabeculum in the eye is removed to relieve pressure caused by glaucoma. It is the most common conventional surgery performed for glaucoma. A partial thickness flap is made in the scleral wall of the eye, and a window opening made under the flap to remove a portion of the trabecular meshwork. The scleral flap is then sutured loosely back in place. This allows fluid to flow out of the eye through this opening, resulting in lowered intraocular pressure. Scarring can occur around or over the flap opening, causing it to become less effective or lose effectiveness altogether.
