Ciliary body

 

The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. The ciliary body produces the fluid in the eye called aqueous humor. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on a near object. This process is called accommodation.

A type of tumor called melanoma can develop in the iris. Most eye melanomas form in the part of the eye that you cannot see in the mirror and therefore they can be difficult to detect. Early melanomas do not cause any symptoms making them hard to diagnose.
