Glaucoma is an eye disease that can be treated mainly via the administration of pharmaceuticals. If despite the use of drugs, or Laser (SLT Laser) the intraocular pressure is not sufficiently regulated, and there still exists the risk of deterioration of the optic nerve, it should be treated surgically.
The traditional surgical procedure for glaucoma is called "trabeculectomy". The surgery is performed under local anesthesia and is intended to create a new path for the permanent removal of the aqueous humor. A successful trabeculectomy involves the creation of a bubble (filter cartridge) in the upper part of the eye, where liquid is temporarily retained prior to absorption by the surrounding vessels.
In addition, there is the trabeculectomy and the implantable artificial valve mechanisms of various materials (Ahmed valve, Express, etc.) to the controlled outflow of aqueous humor.
The type of glaucoma, the state of the tissues, and previous procedures performed, will provide the criteria by which the surgeon will decide which surgical method he will use to regulate intraocular pressure.
