Retained nonmagnetic old foreign body in iris or ciliary body – http://id.who.int/icd/entity/475371982

This refers to retained (non-magnetic) (old) foreign body in the 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. The color of the iris is often referred to as "eye color." It is also of the circumferential tissue inside the eye composed of the ciliary muscle and ciliary processes. It is triangular in horizontal section and is coated by a double layer, the ciliary epithelium.
