The Ciliary Ring is located in each eye
in the human body.
It is the modern name for one of the three "zones" of the ciliary
body (connecting the choroid
with the iris).
The ciliary ring is also know as the orbiculus ciliaris,
another descriptive term that is used is older textbooks and medical papers.
The ciliary ring (or "orbiculus ciliaris")
is an area approx. 4 mm wide in which the ciliary body is connected to
the anterior (front) part of the choroid.
This is primarily a connecting component and as such does not have as
active a role as the ciliary
muscle, for example.
The subject of visual (also known as "physiological") optics
is a key component of many courses within the fields of both biology and
physics. It is also an essential consideration in the design of displays
and control units used in many applications from televisions and mobile
telephones to advanced aircraft. In the context of engineering "visual
optics" is one of several medical and psychological topics in the
important area of "Human Factors".
