− | Aqueous humour is produced by ciliary processes of '''ciliary body'''. It provides nutrients for lens and cornea. It also maintains intraocular pressure (25mm.Hg), and is replaced several times a day (2µl/min). An increase in intraocular pressure can cause glaucoma. | + | Aqueous humour is produced by ciliary processes of '''ciliary body'''. It provides nutrients for lens and cornea.
