Uveitis & Ocular Inflammation

What is Uveitis & Ocular Inflammation?

Ocular inflammation is swelling and inflammation of the eye tissue as a result of inflamm. The part of the eye that is commonly affected is the middle layer of the eye known as the uvea which consists of the iris, ciliary body and choroid. Inflammation of the uvea is known as uveitis. Uveitis can occur in the front, middle, back and the whole of the eye as well.

Types of Uveitis

Uveitis may be differentiated based on the part of the uvea that is affected:

  • Iritis: Also known as anterior uveitis, iritis affects the iris, the coloured part of the eye that surrounds the pupil.
  • Cyclitis: Also known as intermediate uveitis, cyclitis affects the ciliary body, a circular structure behind the iris that changes the shape of the lens to focus your vision.
  • Choroiditis: Also known as posterior uveitis, choroiditis affects the choroid, a thin layer in the posterior part of the uvea that contains many tiny blood vessels.
  • Diffuse uveitis: This type of uveitis affects all parts of the uvea.
