Asking Science for a Refund

On our recent trip to the opthamologist, who after another 2+ hour wait remains confused about why Elliot's eyes made such a dramatic downturn three months post-op, we were encouraged to have another MRI done.

And exactly WHY would I subject that child to another MRI?
Deny him food, put him under, and have him put in a machine that makes the smoke monster on Lost sound sheepish because he might have some kind of flare up that causing these changes?
Can you DO anything about these changes?
Can we prevent these flareups?

If you're just fucking curious, you'll have to poke around on some other CMV kid, because my child is not a science experiment, and we have not donated his body to your cause.

Why can't doctors of children with a host of specialists coordinate care and actually TALK to each other? A quick call to his Infectious Disease doc and/or neurologist would tell him all he needs.

So what to do now? I'll wait two weeks (and hold my son down while I put on his glasses), then wait two hours to see this doctor again, and ask him if he thinks my son has a brain tumor or some other legitimate reason for an MRI. And I'll wait to see him again because I have no choices on who to see. He is, all at once, the best and worst doctor in the city.
