Glaucoma

The number of people with glaucoma was estimated to be 76 million worldwide in 2020, and expected to rise to 112 million by 2026¹. Glaucoma is often caused by a build-up of intraocular pressure (IOP) within the eye. This happens when drainage of the aqueous humour (a watery fluid that fills the space between cornea and lens and helps maintain normal pressure in the eye) is blocked. This excess pressure can damage the optic nerve at the point where it leaves the eye to carry visual information to the brain. It can lead to vision loss and cause blindness, which is irreversible.^2,3
