So when I was at my oncologist's office last week I finally asked him about the problems I have been having with my eye since my large RAI treatment. I go to a thyroid support group and two woman in the group have had to have tear duct surgery as a result from RAI. When I asked my doctor about it he agreed that it was probably related to the RAI and I would need to see a doctor to have my tear duct "reopened". Has anyone had this happen? I don't think it's completely clogged, but I do believe it is at least partially clogged. Anyone have this happen?
