Ophthalmologists can order any type of test because they are licensed medical doctors. Certain autoimmune conditions such as Sjogren’s syndrome, multiple sclerosis, Bechet’s disease, Grave’s disease, Reiter’s syndrome, and others, are associated with eye problems. Thus, an ophthalmologist may order a blood test to diagnose autoimmune diseases, which is faster. Further, an ophthalmologist can use an optical coherence tomography (OCT) test to detect an autoimmune eye disease. Ophthalmologists also work with autoimmune specialists for coordinated comprehensive care.
