Ciliary processes of the eye. Coloured Scanning Electron Micrograph (SEM) of ciliary processes of the eye. This view looks outwards from the inner eye chamber. At top is the ciliary body (yellow); it is attached to the iris and supports the eye lens. The eye lens (not seen) would be positioned at lower left. Ciliary processes (blue) appear grape-like and are attached to the ciliary body. Ciliary processes form radial ridges (6 seen here) around the eye lens, are attached to the lens, and when moved by ciliary muscles they control the shape of the lens and so focus images onto the retina.
