Ciliary body (the muscle which changes the change of the crystalline lens to bring focus to both near and far objects and produce aqueous humor which bathes the inner structures of the anterior segment of the eye). choroid (the middle layer of the eye between the retina and the sclera) 
 Inflammation can occur in any of these parts. The symptoms, treatment and long term effects will vary to the type of uveitis present. 

Uveitis can be classified in a number of ways. A common classification used is according to location of the inflammation.

Anterior: affects the anterior structures of the eye (cornea, anterior chamber, iris and crystalline lens). This is the most common type of uveitis. Intermediate: affects a region of the eye called the pars plans. It is the least frequent type of uveitis.

Posterior: affects the choroid and retina.

The ophthalmologist will examine your eyes and a perform a thorough past medical history. The ophthalmologist will also dilate your pupils and check the retina and inner part of the eye.

It is sometimes necessary to perform several diagnostic tests such as blood work to help diagnose the problem.

The treatment is focused at reducing inflammation in the eye(s). Reducing the inflammation reduces the risk of long term complications. When uveitis is caused by bacteria, parasites, or fungi, the treatment will be focused and eliminating the infection.

Corticosteroid (cortisone) is usually used as the mainstay of treatment. This type of medication requires strict medical supervision as these drops are asssociated with side-effects such as glaucoma, cataracts or even an infection. They should not be used without supervision.

If corticosteroid treatment is not effective in controlling inflammation, immunosuppressive drugs may be required to help control inflammation.

When inflammation is controlled, the ophthalmologist will slowly reduce the amount of medication and finally withdraw it completely.

Dilating drops are frequently used to help relax the iris and the muscles within the eye to help remove pain or discomfort associated with the uveitis.

It is always helpful to maintain a healthy diet and normal working hours. But when uveitis occurs is important to seek medical attention quickly.
