What is uveitis?
The basic mechanism of the eye consists of the outermost fibrous membrane (including the sclera and cornea), the middle vascular membrane (uvea), and the innermost neuroectodermal layer (retina and optic nerve) )composition.
The uvea consists of three parts: the iris, the ciliary body (also called the anterior uvea), and the choroid (the posterior uvea).
Uveitis is inflammation of the above sites. It should be noted that the uvea has a large number of blood vessels, which play an important role in maintaining the blood-eye barrier.
Therefore, the etiology of uveitis is various and the mechanism is more complicated.
In addition to mechanical damage, there are also autoimmune diseases, some systemic infections and some tumors. can also cause uveitis.
A considerable part of uveitis is also idiopathic in clinical practice, and the cause is unclear.
Anatomically, the color and size are like a dark red grape, so it is called the uvea.

If uveitis is not treated in time, it may cause cataract, glaucoma, retinal edema and even severe retinal detachment and even blindness.
Summary
In addition to idiopathic, uveitis may also For systemic diseases, detailed physical examinations are required, including blood tests, urine tests, imaging tests, etc.
