Blurred vision, light sensitivity, and floating eyes can indicate inflammation in the eye. A visit to an ophthalmologist can reveal multiple causes, including uveitis. Uveitis is inflammation of the uvea, the middle layer of the eye, which is blue or nearly black. The iris, choroid and ciliary body form the uvea. The uvea is a part of the eye with numerous blood vessels. Other names similar to uvea are uvea, uvea and vascular membrane.
Uveitis also affects the lens, retina, optic nerve, and vitreous humor. Inflammation, tissue destruction and the resulting failure of the visual immune system indicate the development of uveitis. As a medical emergency, a thorough examination should be performed by an optometrist or ophthalmologist to determine the extent of the attack. Urgent treatment is needed to control the swelling.
Uveitis can be chronic, but in some cases it is a one-time attack. The disease affects the front, center, or back of the eye. Inflammation of the choroid, ciliary body and iris also leads to panuveitis. There are four types of uveitis.
Inflammation of the iris and ciliary body only leads to anterior uveitis.
The symptoms of anterior uveitis are;
- Blurry sight
- Sensitivity to light
- Eye movement hovering
- Red eyes
- Irregular pupils
Torches in the anterior chamber of the eye
Intermediate uveitis affects the surrounding retina and vitreous humor. Inflammation mainly occurs in the vitreous humor, including vitreitis, posterior cyclitis and vitreitis. Intermediate uveitis is the first manifestation of systemic disease as it is closely related to systemic disease (such as multiple sclerosis). This type of uveitis usually affects children and young people. However, the disease can occur at any age.
Posterior uveitis affects the retina and choroid, so it is called choroiditis. This condition is the least common of these four categories.

Inflammation of the ciliary body, iris and choroid also leads to panuveitis, a disease that severely damages the retina.
Causes of uveitis
The main cause of uveitis is unclear. However, the following factors can contribute.
Autoimmune diseases, such as sarcoidosis, juvenile idiopathic arthritis, sympathetic ophthalmia, spondyloarthritis
Inflammatory diseases, such as ulcerative colitis
Infections such as syphilis, shingles, toxoplasmosis, leptospirosis, Lyme disease, and brucellosis
Side effects of medications such as quinolones and rifabutin
Genetic predisposition factors, such as HLA-B27 and PTPN22 genotypes
Basic condition by blood test
Radiographic X-rays showed coexistence of arthritis, chest X-rays showed sarcoidosis
Extensive fundus research
Uveitis treatment is mainly aimed at reducing inflammation. The ophthalmologist can prescribe the following:
Anti-inflammatory eye drops are usually corticosteroids. If they are inactive, then corticosteroid pills or injections are administered.
Antibiotics and antivirals can treat bacterial and viral infections that can cause uveitis. In some cases, medications that do not contain corticosteroids can be administered effectively.
When uveitis occurs in both eyes and does not respond to corticosteroids, immunosuppressants may be used.
