I agree with Selma, speak to a neurologist. I have had about 8 MRIs and they all show that my condition has flattened the optical nerve on my left eye. What's funny is that I had an eye exam a few months ago and the optometrist stated that nothing is wrong with my eye, yet my vision becomes blurred then doubled as my activity increases. My vision is ok when I'm well rested.
Hi and welcome to the Chiari forum.
Many of us with Chiari do have issues with our eyes and it would be in your interests to also have a neuro optho inspection of your eyes.....
There are also related and non related conditions that should be ruled out as well...Lymes, Lupus and MS since they have similar symptoms as well as conditions that have similar symptoms and are related like syringomyelia, ICP, POTS,IIH,,,CCI,,,Ehlers-Danlos and tethered cord.....
Do talk with a neuro optho and see if they will get you in for a check up....
