Question: I have recently recovered from iritis, and the doctor told me that it was my own immune system attacking my eye. Why does this happen?

  1. This sounds like Yashar’s speciality! But as a matter of interest…whenever you see “itis” on the end of a word, it means “inflammation of” (from Ancient Greek and more modern Latin). So appendicitis is inflammation of the appendix. Bronchitis is inflammation of the bronchi (the air passages to the lungs). Otitis is inflammation of the ear! Inflammation is pretty non-specific though…it can be caused by all sorts of things, including dust, bacteria, viruses, and your own immune system getting out of control.

  2. Well i hope it is all better now!!

    Definitely a question for Yashar, but there’s lots of instances when your body attacks itself and we still don’t know why it happens, mostly!

    They are called “auto immune disorders” and some that you might have heard of are Grave’s Disease, Lupus, Rheumatoid arthritis, Chron’s disease and Type 1 diabetes.

    Here’s a huge list of them, and some more information from wikipedia!

  3. I had to look this up for a second, as I’d never heard of iritis, inflammation of your iris!
    So iritis is a type of Uveitis. Carina is right when she says anything with “-itis” on the end of a word means “inflammation of”. So in this case you had an inflammation iris, the “muscle” at the front of your eye that determines how much light is focused into the eye, also referred to as your eye colour. A quick search gave me this:
    “The most common form of uveitis is anterior uveitis, which involves inflammation in the front part of the eye. It is often called iritis because it usually only affects the iris, the colored part of the eye. The inflammation may be associated with autoimmune diseases, but most cases occur in healthy people. The disorder may affect only one eye. It is most common in young and middle-aged people”.

    So the thing I’d take away from this is that you’re not alone, it can occur in many people. It isn’t always linked with autoimmune disease, but even if it is, you shouldn’t freak out! You should listen to your doctor, and can even see an ophthalmologist (eye doctor – specialist). He probably gave you steroid anti-inflammatory eye drops or something alike to decrease inflammation around that area.

    There are a lot of things that can cause iritis. Anything from an injury and infections all the way to autoimmune disease can cause iritis. But look, don’t go picking the worst of these and worrying about it. The treatment worked. Let’s hope it doesn’t come back

    Hope that helps ๐Ÿ˜€

  4. Really nice responses from our excellent scientists!

    Hey jacob – I wondered how did you discover it? Was your eye itchy or painful? And yeah hope it’s all cleared up now!

  1. Hey Mel,
    One day when I got off the bus my eye was sore and red. I have grass allergies, so my parents just thought it was a reaction, but it just got worse and worse by the minute, eventually becoming scarlet and so sensitive to light that I couldn’t look at the sky – on an overcast day! So I was rushed to hospital and then to my ophthalmologist, and he told me it was iritis!

    But in your 1st message it sounded like everything’s fine now.
    Hope this is the case ๐Ÿ˜€
