Trabecular meshwork bypass is a surgical procedure used to treat glaucoma by creating a new drainage pathway for the aqueous humor in the eye. This bypass technique aims to improve fluid drainage from the eye, thereby lowering intraocular pressure (IOP) and preventing further damage to the optic nerve.

The procedure involves implanting a stent or shunt into the trabecular meshwork, the part of the eye responsible for fluid drainage. This allows the fluid to bypass the natural drainage system, reducing IOP. Trabecular meshwork bypass surgery is typically performed on patients with open-angle glaucoma who have not responded to other treatments, such as medication or laser therapy.

This surgery offers an effective solution for managing glaucoma, providing long-term IOP control with fewer complications than traditional surgeries.
