Uveitis

Inflammation of the uvea, a layer of the eye, is what causes Uveitis. The inflammation of retina and its vessels besides uvea is also included in Uveitis. Presence of blood vessels in aforementioned region makes the condition highly dangerous for eye health. Cell deaths occur due to damaged blood vessels and undernourishment of the region, which results in blindness. Besides this, other conditions include cataracts, glaucoma, cystoid macular edema, endothelin decompression.

Causes of Uveitis

There are three main causes of this disease:

  1. Infections: an infection occuring within the eye or in other parts of the body caused by bacteria, fungus, virus or parasite.
  2. Autoimmune disorder: An attack from the body’s own immune system. Symptoms of behcet disease, ankylosing spondylitis, herpes, rheumatoid arthritis may also appear in the eye.
  3. Idiopathic/Unknown cause:  % 40 of the patients are in this group. The specific cause of it isn’t clear.

Symptoms of Uveitis

Earlier diagnosis help  achieve  more successful and effective results since Uveitis may even cause blindness if left uncontrolled. Therefore the symptoms of this disease should not be ignored. Symptoms might change based on the region it emerges.

  • Anterior uveitis: the part of the eye  where the light enters and the lens exists. Cataracts and blurry vision are main complaints of the patients.
  • Intermediate uveitis:  %15-20 of the patients belong to this category. Most of them are children and adolescents. The patient may see floating images.
  • Posterior uveitis: emerges along with such diseases as behcet,sarcoidosis. Tiny dots and floating images are also the main complaints of this type. Lessened or blurry vision might also be included in the symptoms.

Treatment for Uveitis

Proper treatment of this disease changes based on symptoms of the patient. If the cause of Uveitis is infection, medications include antibiotics and antivirals are prescribed;however, the disease should be treated first if uveitis has emerged along with another disease. The infected part plays a key role in choosing the right medication. Eye drops can be effective only on the front of the eye so it can be used just for anterior uveitis. Another way is surgery for its treatment. Surgical procedures are vitrectomy, cryotherapy, laser therapy. No matter where or why Uveitis emerges, the other disease should be cured first if Uveitis arises along with another disease. It is critical for the patient not to delay his eye exam every three months as it can reoccur even if the patient has been fully cured.
