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 three sets of ciliary muscles in the eye, the longitudinal, radial, and circular muscles. They are near the front of the eye, above and below the [[lens (vision)|lens]]. They are attached to the lens by [[connective tissue]] called the [[zonule of Zinn]], and are responsible for shaping the lens to [[focus]] [[light]] on the [[retina]].

When the ciliary muscle relaxes, it flattens the lens which, generally improvesimproving the focus for farther objects. When it contracts, the lens becomes more convex which, generally improvesimproving 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 of 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]].
