The circular colored portion of the eye is called iris with dark pupil in the center. Inflammation of the iris is called iritis. The muscular fibers of iris controls the light entering the pupil so that we can see clearly, this is done by making the pupil smaller in bright light and big in dim light.
Basics: There are genetic, infectious or traumatic causes of iritis. Inflammatory process is triggered following injury and contaminated by microbes and accumulation of necrotic products at the site of injury. In infectious cases the immune system reacts against molecules and injures the uveal tract vessels and cells.
