Uveitis is inflammation that occurs in the uvea or the middle layer of the eye. This condition is characterized by one or both eyes looking very red, which can be accompanied by pain in the eyes and blurred vision.
The uvea is the middle layer on the inside of the eye consisting of the iris (iris), the lining of the eye blood vessels (choroid), and the connective tissue between the iris and the choroid (ciliary body). The uvea is located between the white part of the eye (sclera) and the light-absorbing part of the eye (retina).
Based on the location of inflammation, uveitis is divided into several types, namely:
1. Uveitis in the front of the uvea (iritis or anterior uveitis), which is inflammation that occurs in the iris.
2. Uveitis in the middle of the uvea (uveitis intermedia or cyclitis), which is inflammation that occurs between the iris and the choroid.
3. Uveitis in the back of the uvea (choroiditis or posterior uveitis), which is inflammation that occurs in the choroid
4. Uveitis throughout the uvea (panuveitis), which is when the entire lining of the uvea becomes inflamed
Uveitis is also divided based on the duration of this disease. Here is an explanation. Acute uveitis, which is a type of uveitis that develops quickly and improves in less than 3 months, while chronic uveitis, which is when inflammation occurs continuously for more than 3 months
Symptoms of uveitis may appear suddenly or develop gradually over a period of several days. Symptoms of uveitis include red eyes, pain in the eyes, blurred vision, eyes become sensitive to light, black spots appear in the field of vision, decreased visual function.
