What is Uvea?
The human eye is composed of three layers of which, Uvea is the middle one. Uvea is not a common term we get to hear often. However, it is one of the complex structures in the eye that’s critical to proper vision. In this section, let’s quickly understand a little more about Uvea and the diseases that could affect its functioning.
Uveitis is one of the most common diseases affecting the Uvea. It refers to inflammation of the Uvea and could occur due to an infection from a virus or bacteria. It could also be a secondary condition that develops due to some other illness present in your body like rheumatoid arthritis, tuberculosis or syphilis and is called as systemic Uveitis.
Uveal tumors, cysts, and uveal trauma are some of the other issues arising in the uveal tissue.
Uvea Problems Continued….
Uvea is the biggest pigmented part of your eyes; the other one being the macula (on the retina). All the other parts are colourless.
Your doctor would perform a series of tests on your eyes like visual clarity, eye pressure and even dilate your eyes to check the inside health of it. If your doctor suspects Uveitis, he/she would perform more tests to identify any underlying problem that’s causing this. You would be asked to share your medical history. Tests like an X-Ray to check for tuberculosis and blood work would be done to identify any autoimmune diseases/other conditions. These tests will help rule out systemic Uveitis.
In the case of systemic Uveitis, the primary disease would be treated and Uveitis would subside on its own. However, if the infection is restricted only to the Uvea, treatment may involve administration of eye drops or treatment involving antibiotics or corticosteroids.
