What causes iritis?
Disease description:
My eyes have been slightly painful today. When I looked in the mirror, I noticed they were a bit red, although not severely so. After a hospital examination, I was diagnosed with iritis. I'm currently using eye drops, and I would like to know what causes iritis?

The causes of iritis can be summarized as follows:
1. Infectious factors: Common infectious pathogens include bacteria, viruses, fungi, and parasites. These pathogens may enter the eye through direct contact or the bloodstream, leading to the development of iritis.
2. Autoimmune factors: Inflammatory autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus may cause the immune system to mistakenly attack iris tissue, resulting in iritis.
3. Trauma: Direct ocular injury or surgical procedures may damage the iris and subsequently trigger iritis.
4. Other systemic diseases: Conditions such as gastrointestinal disorders and systemic infections may also contribute to the onset of iritis.
