The '''ciliary body''' is the part of the [[eye]] containing the [[ciliary muscle]] and [[ciliary processes]]. It is part of the uveal tract -the layer of tissue which provides most of the nutrients in the eye. There are
When the ciliary muscle relaxes, it flattens the lens which generally improves the focus for farther objects. When it contracts, the lens becomes more convex which generally improves the focus for closer objects.
The ciliary body has three functions: accommodation, aqueous humor production and the production and maintanence of the lens zonules.
One of the most eseential roles for the ciliary body is the production of the aqueous humor, which is responsible for providing most of the nutrients for the lens and the cornea and involved in waste management of these areas. It is the main target of drugs against Glaucoma, as the ciliary body is responsible for aqueous humor production; lowering aqueous humor production will cause cause a subsequent drop in the intraocular pressure.
