That's an interesting connection. I am reading lots of women complaining that low estradiol can impact eyesight. So I don't doubt it. Let me know if you find anything more about this.
One last comment:
I would consider going to his colleague who will take care of your estradiol. If you do that for a few months, then you can back to another doctor closer to you and say, "Look! I was on this protocol and felt good and would like to continue." Once you are on a protocol from another doc, I think you'll find they are more open-minded.
