Eyes (Central Nervous System) and Skin (Integumentary System)
About 10 percent of people with IBD have eye problems. The most common of these is inflammation of the uvea (uveitis), which is the middle layer of the eye wall. This can cause symptoms such as pain, blurry vision, light sensitivity and redness. These symptoms will ease up if you are treating your Crohn’s properly.
With Crohn’s comes an increased risk of developing erhthema nodosum [8] or pyoderma gangrenosum [9] on the ankles, shins, or arms. Pyoderma gangrenosum is when you develop pus and deep ulcerations on the skin. Erhthema nodosum is when red bumps appear on the skin. They are usually temporary and will most likely clear up under the right treatment.
