Glaucoma. Artwork showing glaucoma arising from the drainage system of the eye becoming blocked (bottom right) and a normal eye (top right). Glaucoma is an increased pressure in the eyeball due to an excessive amount of aqueous humour (the fluid that fills the eyeball). The increased pressure compresses the optic nerve and blood vessels in the eye, impairing vision. Treatment is with eye drops and in some cases surgery. If left untreated glaucoma can cause total blindness.
