4. Conjunctivitis
Another surface of your body that is affected in a number of cases of Sweet syndrome is the white of your eye, which in medicine is called the cornea. If you have Sweet syndrome, you might feel that your eyes are itchy and tender and that they have a pink or reddish color. This is caused by a reaction that increases the blood flow to the white of your eyes.
Inside your eyeballs, there are small blood vessels that irrigate the tissue of your eyes, and when more blood flows through them, they distend and become bigger. When we see a pink eye, what we are seeing is the blood that is flowing right under the surface of our eyes. The technical term for this phenomenon is conjunctivitis, and it can happen as a part of an immune response that is typical of the Sweet syndrome. This is not contagious.
