What is uveitis?
Uvea is a layer of the eyes that includes the ciliary body, choroid and the iris. Uveitis is the condition of inflammation (swelling) of uvea. The choroid is responsible for supplying blood flow to retina and its layers. Often uveitis occurs when there is swelling of iris. Uveitis is likely to develop due to eye infection or due to autoimmune disorders. It is necessary to get early treatment for uveitis failing which it can lead to permanent loss of vision.
Some of the common signs of uveitis are redness of eyes, swelling, and pain in the eyes. It can also cause blurred vision or decreased vision. For some people, the eyes become sensitive to light. You can also feel dark floaters in the field of vision.
Uveitis can occur in the iris or choroid layer or on the ciliary body of the eyes. For some people all the three layers of the uvea develop swelling. There is gel like substance in the eyes which can also develop inflammation. All the above symptoms can occur either in one of the eye or both. And it can develop gradually or suddenly.
Exact cause of uveitis is not known. It is believed to develop due to autoimmune disorders like Behcet’s disease or spondylitis. In some cases it can occur due to infectious diseases like syphilis, herpes or tuberculosis. Certain types of cancer like lymphoma can affect your eyes causing uveitis.
Who are at risk?
Individuals who have autoimmune disorders for long period, individuals who have genetic predisposition, who often get infections like syphilis or herpes, or individuals who develop sudden eye injury are prone to develop uveitis. In rare cases uveitis can cause complications like damaging the optical nerve or causing retinal problems, or cataract and very rarely permanent loss of vision.
Your eye specialist can easily detect uveitis by closely looking at your eye through device. Your ophthalmologist would diagnose the root cause of the problem before treating it.

Your doctor may recommend corticosteroid for easy healing of inflammation of the eyes. Anti inflammatory eye-drops or oral pills are also effective in treating uveitis. For those with posterior uveitis, a special device is implanted into the eye which would release fixed amounts of corticosteroids into the eye.
In case uveitis is due to viral infection, antiviral drugs are prescribed. For treating autoimmune disorders cytotoxic agents are given. Surgery is the last option for uveitis. The surgeon would remove jelly like substance from the affected eye. Healing of the wound depends on the location of uveitis. Inflammation on the posterior portion of the eye would take more time for healing than in any other part.
Uveitis gets cured most of the time, but it may recur for many times. Chronic treatment measures are to be taken to prevent recurrent flare ups. Once diagnosed with uveitis, it is good to take treatment early, since it can cause irreversible loss of vision if the inflammation is aggressive.
