Ask the experts

I have been diagnosed with Erythema Nodosum, Strep and Pneumonia. Now I have Iritis in both eyes with the left being worse. This has all happened in the last 25 days. Is there any connection between Erythema Nodosum and Iritis?

Doctor's response

Absolutely. A number of the conditions that can lead to erythema nodosum can also feature inflammation of the iris of the eye (iritis). These illnesses include sarcoidosis, Behcet's disease, and inflammatory bowel diseases (Crohn's disease and ulcerative colitis), as well as systemic lupus erythematosus. Further evaluation by your doctor will be necessary to determine what is causing your symptoms.
