H21.5: Other adhesions and disruptions of iris and ciliary body

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 pupil can change in different ways. It is possible for parts of the iris to become attached to the surrounding tissue. It is also possible for the iris to be ripped from its root, for example. These changes can alter the shape of the pupil. You may also find that your vision is worse than usual. The pressure inside the eye can also increase.

Increased pressure in the eye can lead to a person not being able to see as well as they normally can or their eye becoming very sore.
