Many studies have shown that diabetes is related to idiopathic anterior uveitis[8]; while the mechanism has not been fully elucidated, it may be related to autoimmune factors and destruction of the blood-eye barrier or eye ischemia caused by diabetes.[9] Recently, some scholars have proposed that it is related to the cross reaction of serum insulin antibodies in patients with diabetes.[10]. This evidence concerns the gene INS and idiopathic anterior uveitis.
