Diabetes And The Eye By Dr. Iyami Nathan
Diabetes is caused by an autoimmune disease which affects the islets of Langerhans (type 1) leading to little or no production of insulin (which helps in mopping up excess sugar in the bloodstream); or by the inability of insulin to do its job of mopping up excess insulin due to resistance of insulin at the cells (usually common in obese people) or even during pregnancy (gestational diabetes).
