The cornea and lens are also responsible for focusing incoming light on to the retina to create a clear image. To work properly, the cornea needs to be perfectly curved, like the surface of a football. However, in astigmatism the cornea is shaped irregularly, like the surface of a rugby ball.
Celiac disease. Celiac disease is an autoimmune disease in which people canât eat gluten because it will damage their small intestine. If you have celiac disease and eat foods with gluten, your immune system responds by damaging the small intestine. Gluten is a protein found in wheat, rye, and barley.
The Gluten and Diabetes Connection. Celiac disease and type 1 diabetes are autoimmune diseases, and research shows they may have a similar genetic basis. It is recommended that a person with type 1 diabetes be fully tested for celiac disease and gluten sensitivity prior to starting a gluten-free diet.ype 2 diabetes is not autoimmune in nature, and to date, there has not been a connection between type 2 and gluten intolerance. The American Diabetes Association recommends screening children for celiac disease shortly after the diagnosis of type 1 diabetes.
