4. Absolute contraindications for MRI. Any patient that indicates on the MR safety questionnaire that they have or suspect they may have metal in their eye(s) will require an x-ray prior to their MRI scan confirming that their eye(s) are free from metal. This will be verified using previous x-ray records. Any patient whose previous records indicate that they may have had metal in their eye(s) or any patients without any x-ray records will be x-rayed for the purposes of this study. Any patient having current metal in their eye(s), will not be given an MRI scan and therefore will not be recruited into the study.
