Uveitis

Uveitis is a form of eye inflammation. It affects the middle layer of tissue in the eye wall (uvea). Uveitis warning signs often come on suddenly and get worse quickly. They include eye redness, pain, and blurred vision. The condition can affect one or both eyes, and it can affect people of all ages, even children.Possible causes of uveitis are infection, injury, or an autoimmune or inflammatory disease. Many times the cause can't be identified. Uveitis can be serious, leading to permanent vision loss. Early diagnosis and treatment are important to prevent complications and preserve your vision.

Symptoms

The signs, symptoms, and characteristics of uveitis may include:

• Eye redness
• Eye pain
• Light sensitivity
• Blurred vision
• Dark, floating spots in your field of vision (floaters)
• Decreased vision

Although they can appear unexpectedly and worsen quickly, symptoms can also develop gradually. One or both eyes may be affected. The uvea is the middle layer of tissue in the eye's wall. Sometimes there are no symptoms, but uveitis symptoms can be seen during a normal eye checkup. It is made up of the iris, ciliary body, and choroid. The coloured portion of the eye, known as the iris, is found inside the front of the eye. When you look at your eye in the mirror, you will notice the white section of the eye, known as the sclera. The structure behind the iris is called the ciliary body. A layer of blood vessels called the choroid lies between the retina and the sclera.

Depending on which area(s) of the eye are inflamed, you may have one of the following types of uveitis:

•The ciliary body and the interior of the front of your eye (between the cornea and the iris) are both impacted by anterior uveitis. The most common kind of uveitis is known as iritis.
•The retina, the pars plana blood vessels behind the lens, and the gel in the middle of the eye are all impacted by intermediate uveitis (vitreous).
•Posterior uveitis affects the retina or choroid, two layers on the inside of the back of your eye.
•Panuveitis happens when your eye's entire uvea, from the front to the rear, becomes inflamed.
When to consult a doctor: If you believe you are exhibiting the symptoms of uveitis, speak with your doctor. He or she may suggest that you see an eye doctor (ophthalmologist). Seek emergency medical assistance if you experience severe eye pain or if you experience any sudden changes in your eyes
