For other uses, see Iris (disambiguation) . The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.he iris develops from the anterior two layers of an embryonic neuroectoderm structure called the optic cup. The optic cup also produces the iris sphincter and dilator muscles.
The sphincter pupillae is situated in the posterior part of the iris, near the pupil, and consists of smooth muscle. The sphincter pupillae is supplied by parasympathetic fibers by way of the short ciliary nerves, and its contraction results in constriction of the pupil (miosis) (fig. 46-7).nflammation of the cornea (keratitis) or of the iris and ciliary body (iridocyclitis) causes dilation of the anterior ciliary arteries (from muscular branches of the ophthalmic, fig. 46-10), resulting in a rose-pink band of ciliary injection.
