questions about Tube Shunt Surgery

Tube shunt surgery is a common surgical approach to treating glaucoma. The procedure aims to reduce the eye pressure to help prevent further loss of vision from glaucoma.

What is tube shunt surgery?

Tube shunt surgery involves placing a small tube implant in the eye. This tube, less than 1mm in diameter, connects the front aqueous fluid chamber of the eye, where pressure usually builds up, to an area underneath the conjunctiva, or ‘superficial layer’ of the eye. Attached to this shunt is a plate which acts like a reservoir, allowing fluid to drain to a space above it.

One of the main advantages of the tube shunt is that it is more resilient to the healing process which can affect other types of glaucoma surgery such as trabeculectomy. The position of the tube and the reservoir tends to be underneath the eyelid, normally the upper eyelid, so it is not usually cosmetically apparent in most positions of eye gaze for somebody’s who’s had this operation.
