A few weeks ago while experiencing a severe migraine i decided to taper from xanax 1mg 3 times a day. In the end stages I got a strand blurry ness in the corner of my left eye and saw an eye doctor who ran a bunch of tests and found nothing (I did not tell him about the withdrawal) it has not gone away and now for the last few days it has been in my right eye too and taking a xanax seems to help it fade. What is this due to? HELP
