Hi @lisalucier , it’s early days really so hard to tell. On mri there has been no improvement, but no worse so that is good. I have had a visual evoked potentials test before starting chelation and after 6 months and that has improved dramatically. I have just been approved for funding for a second year of chelation, so the hospital must believe it’s worth pursuing. I’m hopeful there will be a visual improvement on mri after the second year
