What Happens In UVEITIS?
Uveitis (pronounced U’VE-I’TIS) means “inflammation of the uveal tract”, or the middle layer of the eye. It is an immunologically mediated reaction in the uveal tract leading to its inflammation. It is important to clarify that there is no infection in uveitis. Uveitis may be an isolated problem or may be associated with inflammation in other parts of the body. It may be a single episode in some patients while in others it may have a tendency to be chronic and recurrent. We therefore thoroughly investigate a patient of uveitis to find a possible cause for this inflammation and its prognosis. To understand about uveitis and its seriousness, it may also be helpful to know the basic anatomy of this tissue of the eye.
Different Kinds Of Uveitis
When any part of the uvea becomes inflamed, the condition is labeled as uveitis. This may be further subdivided depending upon the exact structures involved in the inflammation. Thus, if only the iris is inflamed it is called Iritis. Similarly Cyclitis is inflammation of the ciliary body. Anterior uveitis or iridocyclitis is inflammation of both the iris and ciliary body. Choroiditis or posterior uveitis is inflammation of the choroid. Intermediate uveitis is inflammation of the middle part of the uvea and is commonly also referred to as pars planitis. If all structures (iris, ciliary body and choroid) are inflamed then it is called panuveitis. These are medical terms but are helpful for you to know.
Treatment For Uveitis
Uveitis treatment depends on which areas of the eye are affected and what has caused the condition. A comprehensive eye exam is required to check what kind of uveitis along with a whole battery of tests, like blood tests, X-rays, CT scans, etc. Uveitis treatment involves medication through drops, injections or oral medications.

Frequently Asked Questions
Depending on which part of the eye is inflamed in uveitis different combinations of symptoms may be present. These include redness of the eye, pain, light sensitivity, blurring of vision and floaters. Uveitis may come on suddenly with redness and pain, or it may be slow in onset with little pain or redness, but gradual blurring of vision. These symptoms may also come on suddenly, and you may not experience any pain. The symptoms described above may not necessarily mean that you have uveitis. However, if you experience one or more of these symptoms, contact your ophthalmologist (eye doctor) for a complete exam. Early detection and treatment is necessary, as inflammation inside the eye can permanently affect sight due to glaucoma (high pressure in the eye), cataract (clouding of the lens of the eye), or retinal damage, and rarely, lead to blindness
An ophthalmologist will use instruments to examine the inside of the eye and often can make a diagnosis on that basis. In some circumstances, blood tests, skin tests (Mantoux test), x-rays, and CT scans, and sometimes, even specimens taken surgically from the eye, may assist in establishing the diagnosis and finding its cause. Since uveitis can be associated with disease in some other part of the body, an evaluation and understanding of the patient’s overall medical health is important. This may involve consultation with other medical specialists, including pulmonologists, immunologists or rheumatologists.
The uvea contains many of the blood vessels, which nourish the eye. Inflammation of the uvea can affect the cornea, the retina, the sclera, and other vital parts of the eye. Since the uvea borders many important parts of the eye, inflammation of this layer may be sight threatening and more serious than the more common inflammations of the outer layers of the eye. Also, due to its rich blood supply, the uveal tract is a natural target for diseases originating in other parts of the body. Because the cornea is normally clear, signs of disease may be seen inside the eye, often before signs develop elsewhere in the body.
