I agree with Pam

Since cidp is a disease of the nerves couldn’t it just as well be that and not the ivig? Had you had previous infusions without the eye issues. are you diabetic? I think this cidp takes over my health thoughts so much, I sometimes forget a headache could be just a headache and not related to ivig or cidp. Either way its your eyes they are extremely important so definitely get to the bottom of it and figure out what is causing it—-Best wishes Lori
