H30.2: Posterior cyclitis

Your eye is inflamed in the ciliary body area.

The ciliary body is located in the rear edge around the iris. The iris is a round, colored layer with an opening in the middle. This round opening is called the pupil. Behind the pupil is the lens. The ciliary body holds the lens in its place and controls how spherical it should be. For this purpose, threads from the ciliary body are attached around the lens. The ciliary body also produces fluid and uses it to control the pressure inside the eye.

The rear part of your ciliary body is inflamed. The inflammation may also be affecting the adjacent retina.

If your ciliary body is inflamed, your vision might be worse. You may perceive black spots in your field of vision. The eye may turn red. You may have pain in your eye, or find bright light unpleasant. The inside of the eye can also change.
