  • Anterior Uveitis or iritis – this mainly affects the iris and is the most common type of Uveitis
  • Intermediate Uveitis – this mainly affects the ciliary body (a part of the eye that controls the shape of the lens), although it may also affect the retina (a thin layer of tissue that lines the back of the eye on the inside)
  • Posterior Uveitis – this affects the back of the eye
  • Panuveitis – this affects the middle layer of the eye.
