Not all doctors are guilty of overstating their precautions and suggestions for a procedure to be done before surgery. The mystery is that after being at the clinic for almost 6 hrs. (they are very popular and many people waiting to have their eyes checked), the two doctor's at the clinic did not indicate what they expect might be the problem. When I got home I began my research. I found out many patients did not undergo an MRI (you realize how powerful these machines are ?) . Several friends indicated this has become widespread in protecting the corporate members in owing the clinic for lawsuits. I am trying to protect my hearing and how damaging an MRI can be. The ears are vulnerable to the powerful sounds the MRI gives off. There is another test that looks at the blood lines in the brain and then there is a CT Scan that does help the doctors. I've told them about my hearing buzzing. It falls on deaf ears. What is interesting is that after I saw the eye doctor's, I went to see my new General Practioner for another issue. Never told him about the eye clinic. Out of his mouth he says he wants an MRI of me from the neck down. That's when I realize that two different doctor's were pushing an MRI for their office files within a 2 mos. period of my having seen them. One for the head and the other for the neck down. I withdrew from their services immediately. What about my ears ?? No response. Thank you for your response. It is valuable to me.
