Which group of structures comprises the uvea?

The uvea is the vascular, pigmented middle layer of the eye that sits between the outer sclera and the inner retina. It comprises three structures: the iris, which controls how much light enters by adjusting the pupil; the ciliary body, which produces aqueous humor and contains muscles that change the lens shape for focusing; and the choroid, a rich blood supply that nourishes the outer retina. The retina is the innermost neural layer, not part of the uvea. Therefore, the group that includes iris, ciliary body, and choroid is the correct one.
