### Patient: I'm having trouble with my eyes, doctor. My pupils seem to be unequal in size. And also, I've been experiencing some back pain recently. Can you tell me what's wrong with me?
### Doctor: Based on the symptoms you've given me, it's possible that you might have an autonomic nervous system disorder. This can affect the muscles in your eyes, causing your pupils to be unequal in size, and may also cause back pain as well. We'll need to run some tests to confirm the diagnosis.
