WebGlaucoma is caused by the build-up of fluid in the eye (called aqueous humour, or just aqueous). This causes pressure in the eye (called intraocular pressure or IOP) to increase, which damages the optic nerve and leads to vision loss. An aqueous shunt is a device which is implanted into the eye and improves the drainage of the fluid out of the eye.
