What causes the rear uveitis?
Rear uveitis is an inflammatory condition that affects the deep layers of tissue in the eye, including the retina and choroid. This can cause blurred vision, floating stains, painful eye pain and possibly blindness. The rear uveitis can be caused by several different disorders, injuries and infections. Many cases are related to parasitic and bacterial infections, including toxoplasmosis and syphilis, but some of them are the result of autoimmune conditions such as lupus. In about half of the cases, doctors cannot be detected by the true basic cause of uveitis symptoms.
Toxoplasmosis is a type of parasitic infection that is the main cause of the rear uveitis in young and medium age adults. It can be obtained by consuming non -acted vegetables, insufficiently cooked meat or contaminated water. A person may also develop symptoms after contact with animal feces, especially a dirty cat litter. In addition to problems with discomfort and vision, toxoplasmoónfection can result in fever, confusion and major headaches.
nA number of types of fungi, bacteria and viruses can also cause rear uveitis. Very common fungal infection called histoplasmosis can cause eye problems for several months or even years after contact with pathogen. Infections Syphilis, Herpes zoster and mononucleosis may have all symptoms of painful eye inflammation. People who are positive about HIV, patients with chemotherapy and others with weaker than average immune systems are exposed to an increased risk of uveitis because their bodies are less able to fight pathogens.
Other potential causes of the rear uveitis include chronic autoimmune disorders and eye trauma. Lupus and rheumatoid arthritis are present in a large number of people who develop uveitis. If the eye is pierced or scraped very deeply, dirt and bacteria of the state in the layer of choroids may lead to symptoms of swelling, inflammation and vision loss. Finally, it is possible to make backUveitis has developed without any recognizable cause.
To determine the best treatment of rear uveitis, doctors examine all possible basic causes. The careful eye test that reveals visible spots helps to diagnose toxoplasmosis or histoplasmosis, while blood tests are useful in detecting bacterial or viral infections. The patient may also be asked to provide a complete medical history to reveal all existing autoimmune conditions. Oral anti -inflammatory steroids, antibiotics or drugs designed to block nerve signaling in the eye may be prescribed to help with symptoms. Most cases of rear uveitis can be well controlled if treatment is searched in time.
