What is the function of the uveal tract?

  1. It is the source of blood flow to the ocular tissues.
  2. It is the source of aqueous humour (fluid that fills the inside of the eye) and maintenance of intraocular pressure.
  3. It constitutes the blood-aqueous barrier and prevents undesired blood products from reaching the eye.
  4. The musculature of the ciliary body plays a role in accommodation (adjustments in the eye for near vision)
  5. Eicosanoids (prostaglandins and leukotrienes) are synthesized in the iris and ciliary body. These are involved in miosis (decrease in the size of the pupil in bright light, accommodation) and control of intraocular pressure.
  6. Uveal tissue plays a role in detoxification and anti-oxidation in the anterior segment of the eye.
