|Uveitis is inflammation
of the uvea, the middle layer between retina and sclera.
The uvea contains many of the blood vessels, the veins
and arteries, that carry blood flow to the eye. Inflammation
of the uvea can affect the cornea, the retina, the sclera,
and other vital parts of the eye, thus causing damage
for your sight.
Uveitis has various different causes such as
a virus, a fungus, or a parasite. In most cases, the cause
remains unknown. Inflammation in one eye can lead to a
severe injury to the other eye.
Uveitis may occur suddenly with redness and pain, or slowly
with little pain or redness, but gradually with blurring
There are 3 types of uveitis
1. Iritis or anterior uveitis
When the uvea is inflamed near the front of the eye in
the iris-the anterior part of uvea, it is red and painful.
2. Intermediate uveitis
It affects the muscle that focuses the lens. It is the
inflammation of ciliary body,the middle part of uvea.
An inflammation is located in the posterior part of uvea
and may affect the retinal vessels. It may be called posterior
uveitis or chorioretinitis.
Eye drops such as steroids and pupil dilators
are used to reduce inflammation and pain. Moreover, oral
medication or/and injections is used to treat deeper inflammation.
These drugs prevent adhesion or scar formation or attachment
of iris to lens that causes to secondary glaucoma and
