Uveitis Frequently Asked Questions
What is meant by Uvea?
This is the middle layer of the eye, comprised of Iris, Ciliary body and Choroid. It is a vascular layer that nourishes the eye with nutrients.
Why it is called so?
Uvea in Greek means "Grape". The deep purple color of the Choroid is giving the eye a grape like appearance, hence the name.
What is Uveitis?
Uveitis is inflammation of the uvea or in other words it is swelling of internal eye structures.
What is the importance of Uveitis?
Disease of the uvea affects nutrition of vital structures: the cornea, lens, retina and vitreous, thus causing a breakdown in the function of these structures. Uveitis may be sight threatening and more serious than other common eye disorders.
Are there different types of Uveitis?
There are different types of Uveitis depending on which part of the eye it is affected, depending upon the cause etc (may get recurrence in most of the types of uveitis)
- When the uvea is inflammed near the front part of the eye it is called anterior uveitis.(from cornea to lens) It usually has a sudden onset and may last for 6-8 weeks
- If the uvea is inflammed in the middle of the eye, it is called intermediate uveitis. It can affect vision by causing floaters. Inflammation in the back of the eye is called posterior uveitis,(from lens to optic nerve) which has a slower onset and may last longer.
- When the inflammation affects anterior, intermediate and posterior zones it is called Panuveitis
