H21.9: Disorder of iris and ciliary body, unspecified
The area around the iris of the eye has changed.
The colored iris is located in the center of the eye. There is a black opening in the center of the iris. This is the pupil. The iris also controls how big the pupil is. The ciliary body is located in the eye on the edge behind the round iris. There is a spherical muscle in the ciliary body. This muscle is connected to the lens of the eye by a lot of threads of connective tissue all around it. The muscle can use these threads to change the shape of the lens. The ciliary body also produces the fluid for the inside of the eye.
The area around the iris and the ciliary body can change in various ways. The changes can affect the iris itself, the surrounding area or blood vessels.
An increased amount of fluid can accumulate in the iris, for example. There may also be bleeds or adhesions, for example. It is also possible for the color or shape of the iris to change.
