Hi and welcome to the Chiari forum,
We do have info on Chiari , how to prepare for surgery....and a list of Drs....the list of Dr is not a referral and all may not be true Chiari specialists but a member here has been to, treated by and liked the Dr and added them....,use this list as a tool to help you start researching Drs to find the right one for you....in the meantime educate yourself on ALL related conditions to Chiari and Chiari itself....
Know you are not alone <3
Problems with vision can definitely be a symptom of Chiari. If you want, check out CSFinfo.org. There are some videos on there regarding vision/optic nerves, etc and Chiari. There will also be a symptom list there.
I believe there is a post within this forum of doctors who specialist in Chiari. I recommend scheduling an appointment with one of them.
