How do you classify uveitis?

Uveitis may be classified according to anatomical location into 4 subtypes, depending on which part of the uvea is primarily affected: anterior, intermediate, posterior, and panuveitis. Based on the duration of symptoms it may be further sub-classified as acute or chronic.

Can sunlight cause uveitis?

It may sound like a condition caused by the sun’s UV rays, but uveitis (yoo-vee-eye-tis) is actually an inflammation or swelling of the eye’s uvea. The uvea is located in the center of the eye, between the sclera and the retina, and is responsible for supplying blood to the retina.

What is AC cells?

The anterior chamber (AC) is the aqueous humor-filled space inside the eye between the iris and the cornea’s innermost surface, the endothelium. Hyphema, anterior uveitis and glaucoma are three main pathologies in this area.

What is Vitritis?

Vitreous inflammation, or vitritis, may result from many causes, including both infectious and noninfectious, including rheumatologic and autoimmune processes. Vitritis is commonly vision threatening and has serious sequelae.

What are the main causes of uveitis?

Possible causes of uveitis are infection, injury, or an autoimmune or inflammatory disease. Many times a 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.

Is Iridocyclitis and uveitis the same thing?

When the inflammation is limited to the iris, it is termed iritis. If the ciliary body is also involved, it is called iridocyclitis….Background.

What triggers uveitis?

Uveitis is caused by inflammatory responses inside the eye. Inflammation is the body’s natural response to tissue damage, germs, or toxins. It produces swelling, redness, heat, and destroys tissues as certain white blood cells rush to the affected part of the body to contain or eliminate the insult.

What are the signs and symptoms of uveitis?

Various signs and symptoms can occur in different types of uveitis. There is a new grading system of anterior chamber inflammation and vitreous inflammation by SUN working group. There is also an anatomic and an etiological classification of uveitis.

Which is the best description of toxic uveitis?
