What is uveitis?
Uveitis is an eye disorder characterised by the inflammation of the uvea, a vascular layer located below the sclerotica (the soft part of the eye) which consists of three structures:
- Iris: pigmented area that gives your eyes their colour.
- Ciliary body: just below the iris, it reaches the retina and is responsible for generating the fluid that maintains the correct pressure in the eye.
- Choroid: also known as the posterior uvea, it is located below the retina. This layer is formed by blood vessels and connective tissue, and is basically responsible for feeding the intraocular tissues.
Uveitis can affect some of these parts or all of them (panuveitis), either acutely or chronically. This disease is also often recurring and reappears intermittently, with periods in which there are no symptoms.
