Uveitis

Types of Uveitis Uveitis is classified based on the part of the uvea that is affected:

• Anterior Uveitis (Iritis): Inflammation of the front part of the uvea, primarily the iris. This is the most common form of uveitis.
• Intermediate Uveitis: Inflammation that occurs in the middle part of the uvea, including the ciliary body and vitreous.
• Posterior Uveitis: Involves inflammation of the back part of the uvea, including the retina and choroid.
• Panuveitis: Affects all parts of the uvea, leading to inflammation throughout the eye.

Causes of Uveitis Uveitis can be caused by a variety of factors, including:

• Autoimmune Disorders: Conditions such as rheumatoid arthritis, sarcoidosis, and ankylosing spondylitis can trigger uveitis.
• Infections: Bacterial, viral, fungal, and parasitic infections, such as herpes, tuberculosis, or toxoplasmosis, can cause uveitis.
• Eye Injuries: Trauma to the eye can lead to uveitis.
• Inflammatory Disorders: Conditions like Crohn’s disease and ulcerative colitis are sometimes associated with uveitis.
• Unknown Causes: In many cases, the exact cause of uveitis remains unknown.
