I know Nanners, I didn't think it was associated with UC either but virtually any of the extra-intestinal manifestations that are seen with CD are also seen with UC....
Extra-intestinal symptoms that are not directly related to the inflammation in the colon and include eye inflammation, joint pains, skin rashes or lesions, and mouth ulcers. Scientists are unsure why symptoms outside the colon occur, but they often decrease in severity along with flare-ups.
Eye conditions that can occur with UC include conjunctivitis, episcleritis, uveitis, and iritis. Most eye conditions will improve when progress is made in treating the underlying UC, but some may require treatment. Conjunctivitis, or “pink eye,” is an inflammation of the tissue covering the eye and inner surface of the eyelid and may be treated with antibiotics. Uveitis is the inflammation of the middle layer of the eye wall and symptoms include light sensitivity, pain, redness, blurred vision and headaches. Uveitis is commonly treated with corticosteroids; if left untreated it could result in glaucoma or detached retina. Inflammation in the white of the eye is called episcleritis, symptoms include pain and reddening, and treatment is with a vasoconstrictor or corticosteroid. Iritis is inflammation in the iris and symptoms include pain, light sensitivity, blurred vision, redness, decreased pupil size, and floaters. Steroids and antibiotics may be used to treat iritis.

What shocks me even more is that some UCers can get fistulas too, I still have a hard time believing that one.
