New here but already 3rd post today because as I continue to read, I CONTINUE to Relate! I too have had vision changes during flares....although not yet diagnosed with masto, yet given the meds like gastrocrohm I did NOT use and recently threw away due to expiration....stupid thing I did, will try and get whatever tests now because the more I read the more I am hoping THIS time this will be something they can relate Everything else to, anyway as far as the eye problems. I have always had perfect vision, even after 50, until about 3 to 4 years ago, then I had noticed that when I felt bad my vision and clarity would change, and then go back, now it just gets worse but doesn't ever go back as good as it was...20-20, they used to say I had Eagle Vision! No more though. Also when they dialate My eyes, I get the same Reaction! They Hurt SO bad and I look like an Alien, and it takes DAYS for them to go back down...this can't be right? Yet whenever I've complained about this happening they ignore me...haven't been in a while, when I go back I'm going to mention it....again. Thanks for reminding me...Debbie Ciolli

I just wanted to note here that the eyes are full of Mast cells. I have had a lot of issues with my vision. I think this may have lead to my Wet macular degeneration before my diagnosis. When I saw my specialist at Mass Eye and Ear in Boston this past winter for my yearly checkup his assistant told me she was doing research with mice and the stabilizing effect of cromolyn sodium on the mast cells in the eyes!! I know I may sound like a broken record in my posts but I can not stress enough what a difference the Low Histamine diet has had including stabilizing my vision. Of course staying on top of medications, keeping the stress low (yeah right ) and doing my best to avoid those triggers! I have also started to try the rotation diet noted in another post and this has been great! I thought my diet may be getting even more limited but I think this is change is working.
This doesn't mean that I still don't have focus issues but I have not had another ocular migraine since my diet change (I went 3/4 blind while at work for an hour - with no pain, so I was a bit panicked with what was happening  !) You need to try and keep those histamine levels as low as possible. I hope this helps.

Can you give any more detail on the Optoman eye testing?  I don't know if it was done on me or not.
