Hi, Yes I have had years of 'odd' results - mostly after fasting and glucose tolerance tests too. But, hang in there you need a correct diagnosis, and one that you are going to be happy with. I have had visual problems too - but it seems that these could be visual migraines - have to see the doctor. But, I have damage behind one eye, so like I said, I would recommend you hang in there for a correct result. The HbA1c seems to be the most reliable, finger prick tests are what your glucose levels are at that moment which vary from meal to meal, and any exercise. So take care, and ask to see a Endocrinologist at your local hospital.
