If you think you may be developing Graves' ophthalmopathy, you may need to see both an endocrinologist (a doctor who specializes in problems with hormones) and an ophthalmologist (eye doctor). If you know you have Graves' disease, your doctor should be able to find out if you have the eye problem with a standard eye exam.
In some cases, you may need blood tests, or imaging tests like a computerized tomography (CT) scan or a magnetic resonance imaging (MRI) scan. With a CT scan, X-rays are taken from different angles and put together to make a more complete picture. An MRI uses powerful magnets and radio waves to make detailed images.
If you haven't been diagnosed with Graves' disease, step one probably will be to get your thyroid hormone levels checked with a simple blood test.
