Labelled Diagram of the Eye

The orbiculus ciliaris is an older (now lesser-used) name for the ciliary ring which is located in each eye in the human body. This is one of the three "zones" of the ciliary body (connecting the choroid with the iris).

The orbiculus ciliaris (or 'ciliary ring') is an area approx. 4 mm wide in which the ciliary body is connected to the anterior (front) part of the choroid. It is primarily a connecting component and as such does not have as active a role as the ciliary muscle, for example.
