Trabeculectomy
Trabeculectomy
Trabeculectomy (pronounced tra-beck-u-LEK-toe-me) is a surgical procedure often used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures.
Etymology
The term "trabeculectomy" is derived from the Latin word "trabecula," which means "small beam," and the Greek word "ektome," which means "excision."
Procedure
During a trabeculectomy, a small piece of tissue in the drainage angle of the eye is removed to create a new channel for the aqueous humor to drain from the eye. This helps to lower intraocular pressure. The procedure is typically performed under local anesthesia and can be done as an outpatient procedure.
Risks and Complications
Like any surgical procedure, trabeculectomy carries some risks. These may include infection, bleeding, and low or high eye pressure. In some cases, the new drainage opening can become scarred and closed, causing eye pressure to rise again.
