The glaucoma valve acts as an alternative pathway for the ophthalmic fluid to exit from the inside of the eye to the outside of the eye.

It is used in advanced cases of glaucoma or after the failure of traditional surgeries to reduce high intraocular pressure, or in some special cases such as: unresponsive pediatric glaucoma, glaucoma after corneal transplantation, or glaucoma associated with the formation of foreign blood vessels inside the eye.

Glaucoma Valve Surgery:

The operation is performed under local anesthesia by installing the main part of the valve on the wall of the eye and then inserting the valve tube into the anterior cabinet of the eye. Intraocular fluid filtering occurs through the valve to the back of the eye ball to obtain safe degrees of intraocular pressure

Types of glaucoma valve:

Pressure Sensitive Glaucoma Valve

The valve opens when the intraocular pressure reaches a certain limit so that the pressure does not exceed this limit and is characterized by a quick response of intraocular pressure to it immediately after the operation

Non valve Glaucoma Shunt:

The valve tube is closed during the operation for a period of three months until the entire parts of the eye tissue heal after surgery, then the valve is opened to disturb the intraocular pressure. This method is characterized by greater success rates
