Patient's Complete Guide to Uveitis

Overview of Uveitis

The eye has three layers that lie flat against each other and form the eyeball. These layers are:

  1. The outer layer containing the sclera of the eye
  2. The middle containing the choroid
  3. The inner layer containing the retina

Uveitis ( Aankh Ki Darmiani Ta Ki Sujan /آنکھ کی درمیانی تہ کی سوجن)  is the inflammation of the uvea which is also known as the middle layer of the eye. Uveitis causes swelling and destroys the eye tissues. Uveitis can take a turn for the worst very quickly. The symptoms and signs are there for a short time before the infection gets worse.

It can simultaneously affect both eyes and appear in all age groups. It can be mild, or serious leading to permanent blindness.
Sometimes uveitis is not limited to the uvea and can also damage and affect the
lens, retina, optic nerve, etc causing vision problems and blindness.
This disease is more specifically described by which part of the eye is inflamed and based on that known as:

  • Anterior Uveitis
  • Intermediate Uveitis
  • Posterior Uveitis
  • Panuveitis Uveitis

It can be both infectious and non-infectious.
