My son visited an ophthalmologist after a routine visit to the optometrist showed possible swelling in both optic nerves. The ophthalmologist called today and said that he needs to get an MRI because there are indications of increased pressure on his brain. We are in the beginning stages of scheduling the MRI and need to consider whether he should be sedated. He is very calm and can be still for periods of time, but I am worried that this is critical and if he moves the MRI would have to be repeated. I have no experience with MRIs. I am going to talk the pedi as well, but some real world experience is helpful to hear. Thanks.
