Hypopyon in anterior uveitis, seen as yellowish exudation in lower part of anterior chamber of eye In the United States uveitis accounts for about 10%-20% of cases of blindness. While initial treatment is usually successful, complications include other ocular disorders, such as uveitic glaucoma, retinal detachment, optic nerve damage, cataracts, and in some cases, a permanent loss of vision. Any underlying disease, for instance herpes zoster ( shingles) will also require treatment. Treatment usually involves the use of steroids, most commonly as eye drops. Further procedures may be required to identify any underlying disease. Urgent treatment is required to control the inflammation. Uveitis is an ophthalmic emergency and requires a thorough examination by an ophthalmologist or optometrist, including dilation of the pupil to allow better visualisation. The incidence is approximately 1:4500, most commonly between the ages of 20вЂ“60. While the eye is a relatively protected environment, its immune mechanisms may be overcome resulting in inflammation and tissue destruction associated with T-cell activation. Uveitis may arise spontaneously and associated with some genetic factors, or be associated with a wide range of conditions including autoimmune disease and infections. Symptoms include pain, floaters and blurred vision, and clinical examination may show redness and an irregular pupil, while ophthalmic examination shows dilated ciliary blood vessels and the presence of cells in the anterior chamber. In the panuveitic form, all parts are involved. Uveitis is described anatomically, by the part of the eye affected, as anterior, intermediate or posterior, from front to back. The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid. Uveitis ( / ЛЊ juЛђ v ЙЄ aЙЄ t ЙЄ s/) is the inflammation of the uvea, the pigmented layer that lies between the inner retina and the outer fibrous layer composed of the sclera and cornea.
