Did the MRI show anything such as possible scar tissue?
First surgery does not cure you of Chiari it only helps slow progression and may help with some symptoms......it is possible jumping rope may be ok for you.....but we are all different so some of us can not jump rope.....so if you try jumping rope and have no effects then it is ok for you.....if your symptoms increase or are triggered then it is not the right activity for you.
Have you had a recent MRI...and when did the eye issues start?
Hi and welcome to the Chiari forum.
May I ask how long since your surgery? If you continue to have eye issues you should go to to a neuro optho.......
As for the jumping jacks it will depend on how long since your surgery and what the neuro optho has to say about your eye.
