The pressure within the eye that helps to maintain the shape of the eyeball, due to the balance between the rate of production and removal of aqueous humour. Aqueous humour is continually produced from the ciliary body and exits from the drainage angle (a network of tissue between the iris and cornea). If drainage is impeded, intraocular pressure builds up (a condition known as glaucoma). If the ciliary body is damaged (as a result of prolonged inflammation), less fluid is produced and the eye becomes soft.
