The uvea contains a large number of blood vessels, so they supply significant blood irritation to the eye, especially in the retina; so if there is a process of Uveitis, it can produce alterations in vision since the retina is the part in charge of the transformation of images to nerve signals.
There are different types of Uveitis, depending on the area where the inflammation occurs:
- Iritis: it is the most common type of Uveitis, and it is the one that affects the front part of the eye. It is also called anterior Uveitis due to the area of inflammation. The duration can be approximately eight weeks, and they can be recurrent.
