Uveitis refers to the inflammation of the middle layer of the eye that consists of the choroid, ciliary body and iris, states MedicineNet. Uveitis can be caused by an injury to the eye, virus infection, inflammatory diseases, parasites or bacteria, notes WebMD.
There are four major types of uveitis: diffuse uveitis, anterior uveitis, intermediate uveitis and posterior uveitis, indicates Marilyn Haddrill for AllAboutVision.com. Diffuse uveitis, also called panuveitis, is the inflammation of all areas of the uvea. Anterior uveitis affects the iris, or the ciliary body and iris. Intermediate uveitis affects the ciliary body, while posterior uveitis is the inflammation of the choroid and retina, explains Medical News Today.
Symptoms of uveitis may include eye pain; blurred vision; irritation and eye redness; and floating spots before the eyes, according to WebMD. Different tests are carried out to diagnose uveitis, including eye tests, blood tests and X-rays. The doctor may also review any existing medical conditions and family history of medical disorders, states MedicineNet.
Since uveitis is serious, treatment begins right away. Eye drops containing steroids may be prescribed to reduce swellings as well as drugs to relieve the pain. Dark glasses may also be recommended to reduce sensitivity to light, indicates WebMD. If uveitis is caused by an infection, an anti-infective medication may be used to treat the underlying infection, explains MedicineNet. It is important that uveitis is treated early since it has numerous serious complications that can result in permanent vision loss, according to WebMD.
