TRABECULECTOMY Meaning and
Definition
-
Trabeculectomy is a surgical procedure performed to treat glaucoma, a condition characterized by increased pressure within the eye that can damage the optic nerve and lead to vision loss. The procedure involves creating a small hole or flap in the sclera (the white outer layer of the eye) to create a new drainage pathway for the aqueous humor, the fluid that circulates in the front part of the eye.
During a trabeculectomy, the surgeon removes a small piece of tissue from the eye, particularly the trabecular meshwork and the adjacent structures, which are responsible for draining the aqueous humor. This creates a new opening for the fluid to leave the eye and lowers the intraocular pressure. The surgeon may also use an antimetabolite medication, such as mitomycin C or 5-fluorouracil, to inhibit the growth of scar tissue and improve the success rate of the surgery.
Trabeculectomy is typically performed under local anesthesia, and the patient may be prescribed eye drops or medications to prevent infection and reduce inflammation following the procedure. Regular follow-up visits are necessary to monitor the eye's healing process and ensure the success of the surgery.
Trabeculectomy is considered a standard surgical intervention for glaucoma when medical treatment and other less invasive procedures have failed to adequately control intraocular pressure. It can effectively lower eye pressure and halt the progression of glaucoma, thereby preserving the patient's vision.

Etymology of TRABECULECTOMY
The word "trabeculectomy" is derived from two components: "trabecula" and "ectomy".
1. "Trabecula" comes from the Latin word "trabēcula", which means a small beam or bar. In medical context, it refers to a small fibrous network or meshwork of tissue.
2. The suffix "-ectomy" is derived from the Greek word "ektomē", which means excision or removal of a specified part.
Therefore, "trabeculectomy" combines these components to refer to the surgical removal or excision of the trabecula or trabecular meshwork in the eye. Trabeculectomy is a surgical procedure used to treat glaucoma by creating a new drainage channel to relieve intraocular pressure.
