Uveal tract

The uveal tract is a group of three interconnected structures within the eye that provide nourishment, control eye color, and regulate blood flow. These structures are the iris (the colored part), the ciliary body (which helps focus the eye and produces fluid), and the choroid (a layer of blood vessels supplying nutrients to the retina). Together, they play essential roles in maintaining eye health, vision clarity, and the coordination of eye movements. Since they are highly vascular, the uveal tract is also a common site for certain eye diseases, including tumors and inflammation.
