The combining form cycl/o refers to which part of the eye?

Explanation:
cycl/o points to the ciliary body, the ring-shaped tissue just behind the iris that contains the ciliary muscle and ciliary processes. This part of the eye controls lens shape for focusing (accommodation) and helps produce the aqueous humor that nourishes the front of the eye. The iris is named with irid/o, the retina with retin/o, and the cornea with kerat/o, so cycl/o specifically refers to the ciliary body. Terms built from this root include cycloplegia (paralysis of the ciliary muscle) and cyclitis (inflammation of the ciliary body).
