Trabeculectomy is a surgical procedure used to treat glaucoma by creating a new drainage pathway for the aqueous humor, which helps lower intraocular pressure. This procedure is typically performed when other treatments, such as medications or laser therapy, have not been effective in controlling eye pressure.

During the surgery, a small section of tissue is removed from the eye to create a drainage hole, allowing the fluid to exit the eye and reducing pressure. The procedure is usually performed under local anesthesia, and recovery time varies depending on the individual.

Trabeculectomy can significantly improve the management of glaucoma, reducing the risk of optic nerve damage and preserving vision.
