An autoimmune condition where the eye muscles, tear glands, eyelids and fatty tissues are inflamed. The disorder happens when the immune system attacks the thyroid gland instead of fighting off infections. Since certain proteins found in the thyroid are also found in the eyes, the immune system attacks them too. When that happens, the eyes turn red and swell, causing them to be pushed forward/bulge. The eye muscles also stiffen up, meaning the eyes don’t move together.
